Comprehensive and Detailed Explanation From Exact Extract:

An MSDS (Material Safety Data Sheet), now commonly referred to as SDS (Safety Data Sheet), is a document that provides detailed information on the properties of a particular substance. It includes safety guidelines and emergency procedures related to handling, exposure, fire hazards, and first aid—not installation or configuration instructions.

For a battery backup (UPS device), the MSDS would include emergency procedures such as what to do in case of a chemical spill, exposure to battery acid, or fire hazard due to overheating or chemical leakage. This ensures the safety of personnel and complies with hazardous materials handling regulations.

Comprehensive and Detailed Explanation From Exact Extract:

The issue described—“domain cannot be found” despite the ability to ping the server and access the internet—indicates aDNS resolution problem, not a network connectivity issue. The workstation is currently usingpublic DNS servers (8.8.8.8 and 1.1.1.1)whichcannot resolve internal domain names, such as the ones used in Active Directory environments. To resolve this, the technician needs tochange the DNS settings to point to the internal DNS server, which in most domain setups is thedomain controller itself (likely 192.168.1.10 in this case).

Here’s the breakdown of the incorrect options:

B. Assign a static IP address: The IP is already assigned and functioning; the device can ping and reach the network and internet.

C. Configure a subnet mask: The subnet mask is appropriate for the network range (Class C /24).

D. Update the default gateway: The gateway is valid and allows internet access; this is not the issue.

CompTIA A+ 220-1102 Core 2 Objective Reference:

Objective 1.8 – Given a scenario, use features and tools of the operating system.

Under this objective, candidates must know how to troubleshoot OS-based network configurations, includingproper DNS settings in domain environments.

Issue: Limited network connectivity

Resolution: Refresh DHCP

Verify/Resolve: ipconfig

Issue (drop-down)

Limited network connectivity

Why this matches:

“Internet Down” most commonly indicates the workstation has lost valid Layer 3 connectivity (bad/expired DHCP lease, APIPA address, wrong gateway, etc.). In CompTIA A+ terms, this aligns best with limited connectivity symptoms (can’t reach internet resources).

Resolution (drop-down)

Refresh DHCP

Why this is the most efficient fix:

If the client has:

an expired lease

an APIPA address (169.254.x.x) because DHCP failed

an incorrect IP/gateway from a bad lease

…then the fastest first remediation is to renew DHCP to obtain a correct IP address, default gateway, and DNS servers. This is a standard CompTIA A+ troubleshooting action (quick, low-risk, high-success).

Verify/Resolve (drop-down)

ipconfig

Why this is the correct verification tool:

ipconfig is the primary Windows CLI tool to:

check current IP settings (ipconfig /all)

release/renew DHCP (ipconfig /release and ipconfig /renew)

confirm you received a valid IP + gateway + DNS , which is required for internet access.

What you would do (mapped to those choices)

Using ipconfig to complete “Refresh DHCP” and confirm the fix:

Check current addressing

ipconfig /all

Look for:

Valid IPv4 (not 169.254.x.x )

Valid Default Gateway

DNS servers present

Refresh the DHCP lease

ipconfig /release

ipconfig /renew

Verify outcome

Run ipconfig again to confirm:

You now have a correct IP for the network

Default gateway is populated

If the gateway/DNS populate correctly, internet access typically returns.

The correct answer is C. XDR (Extended Detection and Response) , which is designed to provide holistic security visibility across endpoints, networks, servers, cloud workloads, and email systems . Unlike traditional endpoint-only solutions, XDR correlates data from multiple security layers to detect and respond to advanced threats.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , XDR expands upon EDR by integrating telemetry from network traffic, firewalls, identity systems, and cloud platforms. This enables detection of threats that move laterally or originate outside a single host.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that XDR is specifically designed to detect attacks that bypass endpoint protections by analyzing network-level behavior , command-and-control traffic, and cross-system activity.

The Mike Meyers / Mark Soper Lab Manual contrasts XDR with other options: RADIUS is an authentication protocol, UAC is a local Windows privilege control, and antivirus focuses only on known malware signatures at the host level. None of those provide network-wide visibility and coordinated response.

Because the question explicitly mentions traffic outside the host and at the network level , XDR is the only technology designed to meet that requirement, making C the correct answer.

Thepowercfg commandis a built-in utility for controlling power settings including hibernation. It can be used in scripts and does not require domain access.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“The powercfg command provides granular control of power settings, useful for scripting and configuring systems without Group Policy access.”

Comprehensive and Detailed Explanation From Exact Extract:

Group Policyis the standard administrative tool for enforcing security and configuration settings across domain-joined systems, including disabling guest accounts.

FromQuentin Docter – CompTIA A+ Study Guide:

“Disabling guest accounts and applying consistent security policies across multiple machines is best achieved through Group Policy on a Windows domain.”

The correct answers are E. Set the view extensions to " on " and F. Check the box to view hidden files , because folders located in the root directory are often hidden or protected system folders by default in Windows operating systems. Windows hides certain files and folders to prevent accidental modification or deletion, especially those critical to system functionality.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , File Explorer includes view options that control whether hidden files, protected operating system files, and file extensions are visible. If these options are disabled, users will not see many system-level folders, even when browsing the root of the drive (such as C:\).

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that enabling “Show hidden files, folders, and drives” allows technicians to view directories that are normally concealed, such as configuration or application folders. Additionally, turning on file name extensions helps identify system folders and files more accurately, especially when troubleshooting or guiding users remotely.

The Mike Meyers / Mark Soper Lab Manual reinforces that simply opening File Explorer or adjusting display resolution does not affect file visibility. The correct fix is to modify File Explorer view settings , specifically enabling hidden items and file extensions.

Therefore, enabling hidden files and file extensions is required, making E and F the correct answers.

The user needs to deliver a project status presentation to external stakeholders , which implies hosting a meeting with screen sharing, invitations, and attendee management. Quentin Docter defines videoconferencing as screen-sharing software that allows more than one person to share screens and includes “additional functionality, such as calendar invite, call-in numbers, and attendee management.” He lists Microsoft Teams, WebEx, Zoom, and GoToMeeting as examples and states these tools “are often used to present ideas and collaborate between groups of people.” That exactly matches presenting to external stakeholders.

The other options don’t fit the requirement: WinRM is a Windows remote management protocol (administration, not presentations), RMM is used by IT providers to manage many systems remotely (not stakeholder presentations), and secure file transfer is for moving files rather than delivering a live presentation. Since videoconferencing platforms commonly provide screen sharing, chat, and meeting controls designed for external audiences, Videoconferencing (C) is the correct software type.

Comprehensive and Detailed Explanation From Exact Extract:

At large events such as music festivals, cellular towers may become congested due to the high volume of users attempting to connect simultaneously. This congestion causes slow or failed data connections, which explains the email application being unable to sync or connect. This is a common real-world mobile connectivity issue in crowded areas.

A. Lack of storage would prevent saving attachments, not prevent connection attempts.

B. Company firewalls usually don’t affect mobile access unless specific device restrictions are enforced.

D. Organizers do not have the ability to block the internet signal; only carriers manage mobile bandwidth.

The correct answer is B. Create and assign a security group with adequate permissions , because group-based permission management is the most efficient and scalable way to control access to shared resources. By assigning permissions to a group rather than individual users, administrators reduce administrative overhead and simplify future changes.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , security groups are a best practice for managing access to files, folders, and repositories. Permissions are assigned once to the group, and users inherit those permissions by being members of the group.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that granting administrative permissions is excessive and violates the principle of least privilege. Applying permissions individually increases complexity and the risk of configuration errors, especially as team membership changes.

The Mike Meyers / Mark Soper Lab Manual further clarifies that mapping a network folder does not control permissions; it only provides access to a resource that is already governed by permissions. Group-based access ensures consistency, security, and minimal effort.

Because the requirement is to allow specific actions while preventing deletion—and to do so with the least amount of effort —creating and assigning a properly permissioned security group is the optimal solution, making B the correct answer.

The correct answer is A. Reinstalling the application , because the issue appears to be application-specific rather than system-wide. The problem only affects one game, the operating system is fully updated, and there are no storage constraints. These indicators strongly suggest corrupted application data or a faulty app installation.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , when a single application crashes repeatedly, the first recommended troubleshooting step is to remove and reinstall the app. This clears corrupted files, resets application settings, and ensures the latest compatible version is installed.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that factory resets should only be used as a last resort, as they are disruptive and erase user data. Disabling background applications may help performance issues but does not typically resolve persistent crashes tied to one specific app.

The Mike Meyers / Mark Soper Lab Manual further clarifies that date and time misconfiguration usually affects authentication or certificate validation, not game stability.

Because the symptoms are isolated to a single application and basic system factors have already been ruled out, reinstalling the application is the most appropriate first troubleshooting step, making A the correct answer.

The correct answer is A. DLP (Data Loss Prevention) , because DLP solutions are specifically designed to detect, monitor, and prevent unauthorized transmission of sensitive data outside an organization. Information exfiltration occurs when confidential data is improperly transferred, leaked, or stolen, either intentionally or accidentally.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , DLP technologies enforce policies that restrict how data can be shared via email, cloud services, removable media, or network transfers. DLP systems can block, quarantine, or alert administrators when sensitive data patterns—such as credit card numbers or personal identifiers—are detected leaving the organization.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that DLP focuses on data protection , not user authentication or device management. While IAM controls access to resources and MDM manages mobile devices, neither directly prevents data from being exfiltrated once access is granted.

The Mike Meyers / Mark Soper Lab Manual reinforces that SAML is an authentication framework and does not monitor data movement.

Because the question specifically addresses information exfiltration , the security control designed to prevent it is Data Loss Prevention , making A the correct answer.

The correct answer is A. Check for malicious applications , because excessive data usage, device overheating, and rapid battery drain are classic indicators of mobile malware or spyware running in the background.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , malicious applications can continuously transmit data, mine cryptocurrency, or monitor user activity, all of which cause increased network usage and battery consumption—even when the device appears idle.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that the first step in mobile troubleshooting is identifying whether unauthorized or malicious apps are present. Reviewing installed applications and running a mobile security scan can quickly confirm the root cause.

The Mike Meyers / Mark Soper Lab Manual explains that disabling networks or enabling airplane mode only masks symptoms temporarily and does not remove malware. Factory resets are effective but should be used after confirming malware or if other remediation steps fail.

Because the symptoms strongly suggest malicious background activity , the most appropriate first action is to check for malicious applications , making A the correct answer.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“Applying a BIOS password adds a pre-boot security layer. Screensaver locks help protect logged-in sessions during idle times.”

Comprehensive and Detailed Explanation From Exact Extract:

Background applications can significantly drain a smartphone’s battery, even when the device is idle. A technician should first review which apps are running in the background and consuming power through the battery usage section of the OS. Disabling or restricting power-hungry apps often resolves poor battery life.

A. Storage usage doesn’t significantly affect battery life.

B. End of software support is unrelated to battery performance unless it ' s causing inefficient processes, which would still be secondary.

C. Charger wattage affects charging speed, not battery life after charging.

Comprehensive and Detailed Explanation From Exact Extract:

If unauthorized or non-standard applications are appearing on systems and users are receiving licensing prompts, it’s likely users are installing software themselves. Removing users from the local administrators group will prevent them from installing software without approval and reduce the likelihood of introducing unapproved or malicious programs.

A. Deploying a PKI helps with secure communications but doesn’t address user software installation rights.

C. Blocking suspicious websites is helpful but doesn’t prevent local installations.

D. Stricter UAC may add prompts but can still be bypassed by admin users.

The correct answer is D. Chain of custody process , because chain of custody ensures that evidence collected during an incident response is tracked, preserved, and legally defensible . It documents who collected the evidence, when it was collected, how it was stored, and who accessed it throughout the investigation.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , chain of custody is essential when evidence may be used in disciplinary actions, audits, or legal proceedings. Any gap in documentation can render evidence inadmissible.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that chain of custody provides accountability and prevents claims of evidence tampering. Each transfer of evidence must be logged and verified.

The Mike Meyers / Mark Soper Lab Manual clarifies that while order of volatility determines the sequence of data collection, it does not track ownership or handling. Data integrity best practices ensure evidence is not altered, but they do not provide a record of custody.

Because the question focuses on handling and accountability , the required process is chain of custody , making D the correct answer.

When a spreadsheet becomes very large, opening and processing it requires more memory (RAM). If the system doesn ' t have sufficient memory, it may fail to load the file properly. Upgrading or increasing the available RAM can resolve performance and loading issues with very large files.

A. Restore points roll back system settings, not individual file content.

C. Defragmentation optimizes disk performance but won’t help with memory issues.

D. Network speed has no effect if the file is stored and opened locally.

Comprehensive and Detailed Explanation From Exact Extract:

High battery drain is often due to apps running in the background or using GPS during travel. Thefirst stepshould always be tocheck battery usage statisticsto see if an application is misbehaving.

FromAll-in-One Exam Guide:

“Travel conditions can increase app activity, especially navigation or social media. Check app battery usage before assuming hardware faults.”

Comprehensive and Detailed Explanation From Exact Extract:

User offboarding involves disabling the departing user ' s access to company systems and facilities. Two key tasks typically include:

Deactivating physical access credentials (e.g., key fobs or badges) to prevent unauthorized entry (B).

Suspending or disabling the user’s email account to prevent future use and to retain business communications (D).

A. Quarantining a hard drive is not standard unless malware or legal issues are involved.

C. Purging PII must follow legal retention policies; it ' s not typically an immediate offboarding task.

E. Disabling network ports may be relevant in some cases but is not a standard offboarding step.

F. Blocking MAC addresses is not typical unless the device is considered a security threat.

The correct answer is A. Detailed guides for resolving common issues , because effective deployment documentation must support ongoing troubleshooting and support , not just initial installation. Including known issues and resolution steps allows future technicians to resolve problems efficiently and consistently.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , high-quality technical documentation should include error conditions, common failure points, and step-by-step remediation procedures. This information significantly reduces mean time to resolution (MTTR) and improves service quality.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that help desk documentation should evolve over time, incorporating lessons learned from previous incidents. Troubleshooting guides turn deployment documentation into a practical reference rather than a static record.

The Mike Meyers / Mark Soper Lab Manual further clarifies that email logs are informal and unstructured, vendor contact information is supplementary, and end-user manuals are not intended for technical troubleshooting. None of these provide actionable guidance for technicians resolving future issues.

Because the goal is to ensure long-term supportability and effective troubleshooting , the most important inclusion is detailed guides for resolving common issues , making A the correct answer.

A cable run under a carpet is vulnerable to compression, bending, and repeated physical stress from foot traffic, which can damage the cable jacket, distort the twists, loosen terminations, or partially break conductors—often showing up as intermittent connectivity . Quentin Docter notes that on a wired network, “other wired issues can include bad or poorly connected cables,” and you should check cabling and connections as a cause of intermittent problems. Putting a cable where people walk on it increases the chance it becomes “bad” over time or develops poor connections, producing the intermittent symptoms described in the answer option.

From a safety/professional practice perspective, Mike Meyers emphasizes that unmanaged cables are “dangerous tripping hazards” and that in business environments cables should be “carefully tucked away… or placed under cable runners,” using “proper cable management.” While that supports hazard reduction, the best reason in this question’s choices focuses on network reliability: repeated walking over the cable can cause intermittent issues. So the correct answer is D.

Comprehensive and Detailed Explanation From Exact Extract:

To prevent external access, the technician should avoid exposing the surveillance system’s port to the public internet. Port mapping (also known as port forwarding) is the method used to control which internal devices and ports are accessible from the outside. By not configuring port forwarding for the device, external login attempts are effectively blocked.

B. Subnetting organizes IP addresses but doesn ' t directly restrict access.

C. A static IP ensures consistent addressing but does not secure access.

D. Content filtering is used to restrict web content, not to block access to a web interface.

Aclean installensures all malware is eliminated by completely wiping and reinstalling the OS. System restore or repair may leave traces.

Apps like GPS or roaming services often drain battery during travel.Checking app utilizationhelps identify battery drain sources.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“Monitoring app activity can reveal high-power usage apps running in the background, especially when mobile data or GPS is active.”

The most likely reason a legacy tablet cannot run the latest version of an app is that the tablet’s operating system is end-of-life (EOL) or otherwise too old to meet the app’s supported OS/version requirements. Quentin Docter explains that an OS life cycle ends when it is no longer supported, and that an OS at end-of-life will no longer receive updates (including feature updates), making it increasingly incompatible with modern software that expects newer OS frameworks and APIs. The All-in-One guide reinforces this by noting that apps may fail to launch or install when they are not compatible with the device’s OS version (or related vendor customizations).

While insufficient storage can also prevent an update, that typically produces an “update failed/not enough space” condition rather than a consistent inability to use the latest version due to platform support; Mike Meyers’ Lab Manual specifically calls out free space as a common cause of update failures. MDM restrictions and malware are possible but are less “most likely” for a personal legacy tablet.

Comprehensive and Detailed Explanation From Exact Extract:

PXE (Preboot Execution Environment) allows workstations to boot over the network and download an OS image from a server. It is ideal for automating mass deployments using baseline images across many machines without the need for physical media.

A. An ISO is a disk image file but requires mounting or physical media.

B. Secure Boot is a security feature, not a method of deploying OS images.

C. USB requires manual installation and is not suitable for automated deployment at scale.

Comprehensive and Detailed Explanation From Exact Extract:

When a technician exhausts all troubleshooting steps within their knowledge and the issue remains unresolved, the best practice is to escalate the issue to a higher-level technician or team. Additionally, the technician should clearly communicate the next steps to the customer to maintain transparency and reduce frustration. This ensures continuity of support and upholds customer satisfaction.

B. Dismissing the customer is unprofessional and violates proper customer service protocols.

C. Interrupting the customer and providing excuses escalates the tension and is inappropriate.

D. Continuing to ask questions without new troubleshooting steps wastes time and increases frustration.

Linux is the best choice for a low-cost home lab built from used PCs because it is free/open source and widely used in server environments, making it ideal for practicing server administration and scripting. Quentin Docter explains that Linux was created as a free, open source OS and that it can function as both a workstation OS and a server OS depending on installation and configuration—exactly what a lab for “managing servers” needs. The All-in-One guide also highlights that Linux was made “freely available for everyone,” reinforcing why it fits a low-cost requirement (no licensing cost). Mike Meyers’ Lab Manual similarly describes Linux as a “popular, free, open source” OS and emphasizes the importance of the command line—critical for scripting and automation in admin tasks.

By comparison, macOS requires Apple hardware, Windows typically requires licensing costs, and ChromeOS is designed as a cloud-based/stateless OS centered on web apps and Google Drive, making it less suitable for broad server scripting labs.

In emotionally sensitive situations, it is critical that the technicianprojects confidenceand maintains a calm, positive demeanor to reassure the customer.

FromAll-in-One Exam Guide:

“Confidence and empathy are key when working with distressed users. Demonstrating competence can help ease the customer ' s anxiety.”

MDM hardening often includes enforcing stronger authentication on mobile devices. The phrase “unique to each user” points to something inherent to the individual— biometrics —rather than something the user knows (password/pattern) or something they have (PIV/smart card). Quentin Docter explains: “ Biometric devices use physical characteristics to identify the user. This type of authentication is considered something that you are ,” and lists common implementations including “ fingerprint… scanners .” This exactly matches a fingerprint, which is unique per person and commonly enforced via device policies in MDM environments.

Docter also notes mobile devices increasingly implement biometrics for access control, specifically citing “ fingerprint access control ” adopted by manufacturers. A drawn pattern and a password are knowledge factors and can be shared/observed, while a PIV card is a possession factor (something you have) and can be lost or loaned. Because the question specifies a hardening technique “unique to each user,” the best match is the biometric factor: fingerprint (B) .

The first step the CFO should take is to verify the VPN status . When working remotely, access to internal resources such as databases, file servers, and accounting systems typically requires a secure Virtual Private Network (VPN) connection. Without an active VPN tunnel, the application cannot reach internal database servers, resulting in connection errors.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , database connectivity issues during remote work are most commonly caused by missing or disconnected VPN sessions. Internal applications are often restricted to private IP ranges that are inaccessible over the public internet.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide highlights that VPNs are designed to extend the corporate network securely to remote users. If the VPN is disconnected, authentication to internal services will fail even if the application itself launches correctly.

The Mike Meyers / Mark Soper Lab Manual further explains that restarting the PC or updating the application does not resolve network-path issues. Returning to the office is unnecessary if secure remote access is functioning as designed.

Because the error specifically indicates an inability to connect to a database—and not a corrupted application—the most logical and efficient first troubleshooting step is to confirm that the VPN is connected and authenticated .

A low-level format (also referred to as a zero-fill or full format) writes over every sector on a storage device, effectively destroying the existing data and making recovery nearly impossible. Unlike degaussing, which renders the drive unusable, a low-level format maintains the integrity of the device, allowing it to be repurposed or reused.

A. Deleting partitions does not fully erase data; it only removes references in the partition table.

B. EFS (Encrypting File System) encrypts files but does not securely wipe them.

D. Degaussing destroys the magnetic structure of a drive, making it inoperable and not reusable.

Ticket #8675310

Issue: Limited network connectivity

Resolution: Refresh DHCP

Verify/Resolve: ipconfig /renew

For the Low priority ticket #8675310 (“ A small yellow triangle appeared in the taskbar. I am no longer able to access network resources. ”), the Windows yellow triangle on the network icon is the classic indicator of limited connectivity (often caused by a bad/expired DHCP lease, APIPA address, missing default gateway, or DNS info not being assigned).

Correct PBQ Selections (Ticket #8675310)

Issue

Limited network connectivity

Why (CompTIA logic):

That yellow warning triangle means the NIC is connected at Layer 2 (link is up), but the system likely doesn’t have valid Layer 3 config (IP/gateway/DNS), so it can’t reach network resources.

Resolution

Refresh DHCP

Why this is the most efficient fix:

When a Windows PC can’t access network resources and shows “limited connectivity,” the fastest, lowest-risk fix is to renew DHCP so the PC can pull:

a valid IP address

default gateway

DNS servers

This directly resolves the most common root cause behind that icon.

Verify / Resolve

ipconfig /renew

Why this is the correct verification/remediation command:

ipconfig /renew is the direct command to request a fresh DHCP lease . After renewal, the user should regain access to network resources if DHCP was the issue.

What this fixes (what you’d expect to see)

Before the fix, the attachment ( Output.txt ) in these PBQs typically shows symptoms like:

169.254.x.x (APIPA) → DHCP failed

Missing/blank Default Gateway

DNS not present or incorrect

After ipconfig /renew, you should see a normal private IP (like 192.168.x.x / 10.x.x.x / 172.16-31.x.x ) and a valid gateway/DNS.

1st CLI Resolution

copy " C:\Program Files\Testing\msvcp100.dll " " User-PC02\C$\Windows\System32 " /v /y

2nd CLI Resolution

regsvr32 msvcp100.dll

Why These Are the Correct Choices (Exam Logic)

Why the COPY command is first

The error explicitly states MSVCP100.dll is missing

Other users can run the app → the DLL exists on another system

The fastest, least disruptive fix (preferred by CompTIA) is to:

Copy the known-good DLL into C:\Windows\System32

The /v switch verifies the copy, and /y suppresses prompts — both are enterprise-safe defaults

This restores the missing runtime dependency immediately.

Why REGSVR32 is second

After copying a DLL, Windows may not recognize or properly load it

regsvr32 registers the DLL with the operating system

This ensures:

The Testing application can properly call the runtime library

The fix persists after reboot
