Q101) A user reports that their Windows 10 laptop intermittently disconnects from Wi-Fi, while other devices on the same network remain connected. Which of the following should the technician check FIRST?

1. A) Wireless adapter driver
   B) ISP service outage
   C) Ethernet cable
   D) Screen resolution

Answer: A) Wireless adapter driver

Explanation:

 Intermittent Wi-Fi disconnections on a Windows 10 laptop, while other devices remain connected, are most commonly caused by issues with the wireless adapter or its driver. The wireless adapter is responsible for managing Wi-Fi connectivity, handling network authentication, maintaining signal stability, and managing data transmission to and from the router. If the driver is outdated, incompatible with the current Windows build, or corrupted, it can lead to frequent connection drops, failed reconnections, or weak signal handling.

Option A) is correct because the wireless adapter driver directly controls how the laptop communicates with Wi-Fi networks. The technician should first access Device Manager, locate the wireless adapter under “Network adapters,” and check for warning icons. If a driver warning or error is present, it indicates that the driver may be corrupted, missing, or outdated. Updating the driver from the manufacturer’s website or reinstalling it using Windows Update often resolves connectivity issues. Additionally, verifying that the adapter is enabled and not disabled through hardware switches or function keys is important, as some laptops have physical toggles that can disable Wi-Fi functionality.

Once the driver is verified, other settings such as power management should be checked. Windows 10 may have a feature enabled that allows the system to turn off the wireless adapter to save power. This option can be found in the adapter properties under Device Manager. Disabling this feature ensures the adapter remains active and prevents unnecessary disconnects. Network settings such as forgetting the Wi-Fi network and reconnecting, checking the IP configuration, or using the Windows Network Troubleshooter can help further isolate issues.

Option B) ISP service outage would affect all devices on the network. Since the problem occurs on only one laptop and other devices remain connected, the ISP is not the root cause, and troubleshooting external connectivity is unnecessary at this stage.

Option C) Ethernet cable connectivity is irrelevant because the user is experiencing Wi-Fi issues. While physical cable problems can impact wired connections, they do not affect the functionality of a wireless adapter unless a configuration prioritizes Ethernet over Wi-Fi, which is uncommon in consumer devices.

Option D) Screen resolution settings affect visual display but have no impact on network connectivity. Adjusting resolution will not improve Wi-Fi performance or prevent intermittent disconnections.

After confirming that the driver is updated and configured correctly, the technician can test the laptop on multiple Wi-Fi networks to ensure that the issue is not router-specific. Other potential troubleshooting steps include updating Windows to address known wireless compatibility issues, checking for interference from nearby wireless devices, or replacing a malfunctioning adapter if connectivity problems persist. Proper management of wireless drivers and adapter settings ensures stable connectivity, reduces user frustration, and maintains productivity for the affected laptop.

Q102) A user reports that their Windows 10 laptop is extremely slow when opening applications and browsing files. Task Manager shows unusually high disk usage by the process “Windows Modules Installer Worker.” Which of the following is the MOST likely cause?

1. A) Windows is installing or checking for updates
   B) Hard drive failure
   C) Malware infection
   D) Outdated display driver

Answer: A) Windows is installing or checking for updates

Explanation:

The “Windows Modules Installer Worker” (TiWorker.exe) is a legitimate Windows process responsible for installing, modifying, or removing Windows updates and system components. High CPU and disk usage by this process is expected during update scans, installations, or servicing operations. When this process runs, the system may appear slow, applications may open slowly, and file browsing may become sluggish. This is because TiWorker.exe can consume significant CPU, memory, and disk resources while performing file integrity checks, analyzing system updates, and preparing installations.

Option A) is correct because high resource usage by this process indicates that Windows is performing background update-related tasks. These can include checking for new updates, downloading updates, installing updates, or cleaning up old update files. Task Manager will show spikes in CPU, memory, or disk usage that correlate with the operation of Windows Modules Installer Worker. In most cases, the slowdown is temporary and will resolve once the update process is complete. Technicians can monitor the progress using Resource Monitor or Event Viewer to identify update activity. Scheduling updates for off-peak hours or enabling active hours in Windows Update settings can prevent performance degradation during critical work times.

Option B) Hard drive failure can cause slow performance, file corruption, and read/write errors. However, if Task Manager specifically identifies high resource usage by Windows Modules Installer Worker, the bottleneck is likely software-driven rather than hardware-related. Signs of a failing hard drive include unusual noises, repeated errors accessing files, and slow access across all processes, not just during updates.

Option C) Malware infection can also cause abnormal CPU or disk usage, but in this scenario, the process in question is a known, legitimate Windows service. While a malware scan is recommended as a precaution, the observed behavior aligns with expected Windows Update activity.

Option D) Outdated display drivers may impact GPU-intensive tasks or graphics performance but do not typically consume significant disk or CPU resources associated with system-wide update operations. Performance slowdowns during updates are unrelated to video drivers.

Additional steps for troubleshooting include ensuring that sufficient free disk space exists for update operations, verifying that Windows Update services are running, and checking logs for update errors. Educating users about the expected behavior of Windows Modules Installer Worker helps prevent unnecessary concern during update processes and ensures they understand that temporary slowdowns are part of normal system maintenance.

Q103) A user reports that their Windows 10 laptop cannot print to a shared network printer, even though other users on the same network can print successfully. Which of the following should the technician check FIRST?

1. A) User permissions on the printer
   B) Printer toner levels
   C) Hard drive free space
   D) BIOS version

Answer: A) User permissions on the printer

Explanation:

When a single user cannot print to a shared network printer while other users can, the most likely cause is insufficient user permissions. Windows controls access to shared printers using security settings that determine which users or groups can print, manage printer properties, or see the printer on the network. If the affected user does not have the “Print” permission, print jobs will fail even though the printer is fully operational and accessible to others.

Option A) is correct because verifying user permissions is the first logical step in troubleshooting. The technician should navigate to the host computer or print server, access the printer’s properties, and review the Security tab to ensure the user or group has the correct permissions. If permissions are missing, adding the user to an appropriate group or granting explicit print access restores functionality. Permissions changes may require the user to reconnect to the printer or restart the print spooler service for changes to take effect.

Option B) Printer toner levels impact print quality but do not prevent a single user from printing when others can. Low toner may produce faded prints but will not selectively block access.

Option C) Hard drive free space affects system performance but does not directly influence printer connectivity. While extremely low storage can hinder the print spooler from creating temporary files, the problem is usually consistent across all users rather than isolated to a single account.

Option D) BIOS version is largely unrelated to network printer access. Printer sharing and permissions are managed by the operating system and do not require BIOS intervention unless the printer is integrated into a hardware controller, which is uncommon for networked printers.

Once permissions are verified, the technician may also ensure that the user has the correct printer driver installed, that the print spooler service is running, and that network connectivity is stable. Properly configured user permissions ensure secure, reliable printing while minimizing unnecessary administrative support calls.

Q104) A user reports that their Windows 10 laptop battery drains rapidly even when idle. Task Manager shows high CPU usage from multiple background applications. Which of the following is the MOST likely cause?

1. A) Excessive background applications consuming CPU resources
   B) Low hard drive free space
   C) Outdated display driver

Answer: A) Excessive background applications consuming CPU resources

Explanation:

Rapid battery drain while a Windows 10 laptop is idle is typically caused by CPU-intensive background applications. Even when the device appears idle, processes such as cloud sync software, update services, system utilities, and third-party applications can consume significant CPU resources. High CPU usage increases energy consumption, generates heat, and accelerates battery depletion. Monitoring Task Manager reveals these resource-intensive applications and provides a starting point for remediation.

Option A) is correct because excessive background CPU activity is the most likely cause of battery drain. The technician should review Task Manager to identify which processes are consuming significant CPU resources, disable unnecessary startup programs, and adjust background application settings to reduce power consumption. Enabling Windows Battery Saver mode and configuring power plans to limit CPU performance during idle periods helps preserve battery life. Users should be educated on minimizing background applications, limiting auto-start programs, and closing non-essential utilities to improve efficiency.

Option B) Low hard drive space affects performance and the ability to create temporary files but does not directly cause high CPU usage or battery drain. Storage issues result in slower application performance rather than energy consumption spikes.

Option C) Outdated display drivers may impact GPU-intensive applications or graphical performance, but they do not typically result in high CPU usage by background processes, making them an unlikely cause of battery drain in this scenario.

Option D) Disabled firewall affects network security but does not influence CPU or battery usage. Security software manages network traffic and system access but does not directly cause idle battery drain.

Additional steps include scheduling maintenance tasks during periods of AC power, uninstalling unnecessary applications, and monitoring system resource usage to prevent future battery drain. Properly managing background applications ensures optimal energy efficiency, reduces heat generation, and prolongs battery lifespan.

Q105) A user reports that their Windows 10 system cannot boot after installing a recent update. Which of the following tools should the technician use FIRST to attempt recovery?

WinRE is a dedicated environment built into Windows 10 that offers tools to diagnose and repair startup issues, restore the system, and access advanced troubleshooting utilities. It allows the technician to attempt recovery without performing a full reinstallation, preserving user data and configuration.

Option A) is correct because WinRE provides multiple recovery options. Startup Repair can automatically detect and fix problems preventing Windows from starting, such as corrupted boot files or misconfigured updates. System Restore can revert the system to a restore point before the update, effectively undoing the changes that caused the boot failure. The Command Prompt allows advanced troubleshooting such as rebuilding the boot configuration data (BCD), scanning the disk for errors, and manually uninstalling problematic updates. Safe Mode can boot the system with minimal drivers and services to isolate conflicts.

Option B) Device Manager cannot be accessed if Windows cannot boot. It is used to manage drivers in a working system but cannot repair startup failures caused by updates.

Option C) Disk Cleanup removes unnecessary files but does not address non-booting systems. It is useful after the system is operational but cannot repair startup issues.

Option D) Task Scheduler automates tasks but does not affect boot processes. Scheduled tasks do not influence startup failures caused by updates.

After accessing WinRE, the technician should first attempt Startup Repair. If unsuccessful, performing a System Restore or using command-line tools to repair corrupted boot files is appropriate.

   B) Upgrade the CPU
   C) Update the graphics driver
   D) Replace the RAM

Answer: A) Delete unnecessary files and run Disk Cleanup

Explanation:

Low disk space warnings occur when the storage on the primary drive is critically low. Windows 10 requires sufficient free space for temporary files, page files, system updates, and restore points. When the C: drive is nearly full, system performance can degrade, updates may fail, and applications may not function properly. Addressing low disk space is critical to maintaining system stability and user productivity.

Option A) is correct because removing unnecessary files and using Disk Cleanup directly addresses the lack of free storage. Disk Cleanup is a built-in utility that removes temporary files, cached data, old Windows update files, recycle bin contents, and other non-essential files. Deleting unnecessary personal files, uninstalling unused programs, and moving large media files to external storage further increases available space. In addition, enabling storage sense in Windows 10 automates disk cleanup for temporary files and optimizes storage usage.

Option B) Upgrading the CPU will improve processing speed but does not increase storage capacity. Low disk space is independent of CPU performance, so this option does not resolve the issue.

Option C) Updating the graphics driver may improve visual performance and compatibility with applications but has no effect on free disk space. Drivers primarily affect GPU operations, not storage.

Option D) Replacing RAM increases memory capacity, which may improve multitasking and system responsiveness, but it does not impact available disk space. Low storage warnings will persist regardless of memory upgrades.

After performing Disk Cleanup, it is recommended to monitor disk usage and maintain at least 10–15% free space on the C: drive. This ensures that the operating system and applications have room to operate efficiently. For long-term solutions, upgrading to a larger SSD, utilizing cloud storage, or regularly archiving old data can prevent recurring low disk space issues. Effective disk management improves performance, prevents errors, and extends the lifespan of the storage device.

Explanation:

When a Windows 10 system cannot print to a locally connected USB printer while other USB devices work fine, the most common cause is a missing, outdated, or corrupted printer driver. Drivers are essential for communication between the operating system and the printer. Without a compatible driver, Windows cannot translate print commands into instructions the printer understands, resulting in failed print jobs even if the USB connection is functional.

Option A) is correct because verifying that the printer driver is installed and up to date directly addresses the root cause. The technician should access Device Manager to check for the printer under “Printers” or “Universal Serial Bus controllers.” Warning symbols indicate driver issues. Installing the latest driver from the manufacturer’s website or using Windows Update ensures compatibility with the Windows 10 build. Reinstalling the driver can resolve corruption issues. Additionally, confirming that the printer is set as the default device and that the print spooler service is running ensures proper operation.

Option B) Hard drive space does not affect the ability to communicate with the printer unless the drive is so full that the print spooler cannot create temporary files. In typical scenarios, low disk space is not the cause of a single printer connectivity issue.

Option C) Screen resolution affects display quality but does not impact USB printer connectivity. Adjusting resolution will not restore printing functionality.

Option D) Firewall settings primarily affect network traffic. A local USB printer communicates directly with the computer through the USB interface, so firewall configuration is not the issue unless the printer is network-enabled and connected via the firewall.

Once the driver is verified, other troubleshooting steps may include testing different USB ports, restarting the system, or testing the printer on another system to confirm hardware integrity. Proper driver installation ensures reliable printing and prevents user frustration while maintaining productivity.

Ensuring Windows is fully updated prevents compatibility conflicts between drivers and the OS.

Option B) Low hard drive space affects system performance and the ability to store temporary files but does not directly cause screen flickering. While storage constraints can affect overall system responsiveness, they do not produce visual anomalies specific to applications.

Option C) Incorrect screen resolution may distort images or text, but it does not produce intermittent flickering. Resolution problems are predictable and static, unlike dynamic driver-related issues.

Option D) Disabled firewall affects network security but has no effect on GPU operations or display rendering. Screen flicker is unrelated to firewall settings.

After updating or reinstalling the driver, the technician should test other applications to confirm that the issue is resolved. Monitoring GPU performance and temperature ensures that hardware is functioning correctly. Proper driver management ensures visual stability, enhances user experience, and prevents graphical disruptions in daily operations.

Q118) A user reports that their Windows 10 system cannot boot after a recent update. Which of the following tools should the technician use FIRST to attempt recovery

1. A) Windows Recovery Environment (WinRE)
   B) Device Manager
   C) Disk Cleanup
   D) Task Scheduler

Answer: A) Windows Recovery Environment (WinRE)

Explanation

When Windows 10 fails to boot following an update, the Windows Recovery Environment (WinRE) provides the first and most effective recovery option. WinRE is a dedicated environment built into Windows that offers tools for diagnosing and repairing startup issues, restoring the system, and performing advanced troubleshooting. Using WinRE minimizes data loss and avoids a complete system reinstall.

Option A) is correct because WinRE provides multiple recovery tools: Startup Repair automatically detects and fixes issues preventing Windows from booting, such as corrupted boot files or incomplete updates. System Restore reverts the system to a previous restore point before the problematic update. Command Prompt allows advanced troubleshooting, including rebuilding Boot Configuration Data (BCD) and running disk repair utilities. Safe Mode loads the system with minimal drivers and services, helping isolate driver or software conflicts. Using these tools in a structured approach ensures the highest likelihood of successful recovery.

Option B) Device Manager cannot be accessed if Windows cannot boot. It is used to manage drivers and devices in a functioning system but does not provide recovery tools for startup failures.

Option C) Disk Cleanup removes temporary files and frees storage space but cannot repair a non-booting system. This tool is useful after recovery but not for initial troubleshooting of boot failures.

Option D) Task Scheduler automates tasks but does not affect the boot process. Scheduled tasks cannot resolve startup failures caused by updates.

After accessing WinRE, the technician should attempt Startup Repair first. If unsuccessful, using System Restore or command-line repairs is appropriate. Proper documentation of recovery steps ensures efficient handling of future update-related boot failures and restores normal system operation while preserving user data.

Q119) A user reports that their Windows 10 laptop cannot connect to a VPN, although the VPN works on other devices. Which of the following should the technician check FIRST?

1. A) Firewall or antivirus settings blocking VPN traffic
   B) ISP service status
   C) Physical Ethernet cables
   D) Screen resolution

Answer: A) Firewall or antivirus settings blocking VPN traffic

Explanation:

If a VPN functions on other devices but fails on a specific Windows 10 laptop, the issue is likely local to that device. Firewalls and antivirus software can block VPN protocols or client applications, preventing secure tunneling and authentication. This is a common cause of VPN connectivity issues that affect only a single device on an otherwise functional network.

Option A) is correct because the technician should first check firewall or antivirus settings. Temporarily disabling security software allows testing of the VPN connection. If successful, the security software is blocking traffic, and exceptions or rules must be configured to allow VPN traffic. Opening necessary ports or allowing the VPN client through the firewall restores connectivity without compromising overall system security. Additionally, verifying the VPN client configuration, updating software, and confirming credentials ensures compatibility with the OS and network environment.

Option B) ISP service outages affect all devices. Since other devices successfully connect to the VPN, the ISP is not causing the issue.

Option C) Physical Ethernet cables do not affect VPN connections over Wi-Fi. Cable issues are only relevant to wired connections.

Option D) Screen resolution has no effect on VPN functionality. Display settings do not impact network tunneling or authentication.

Once security software is configured correctly, the technician should monitor the VPN connection and test stability. Proper firewall and antivirus configuration ensures secure, reliable VPN access while maintaining overall system protection.

Q120) A user reports that their Windows 10 laptop screen goes black intermittently while using web browsers. Which of the following is the MOST likely cause?

1. A) Outdated graphics driver
   B) Low hard drive space
   C) Incorrect screen resolution
   D) Disabled firewall

Answer: A) Outdated graphics driver

Explanation:

Intermittent black screens in web browsers are commonly caused by outdated, corrupted, or incompatible graphics drivers. Web browsers often use hardware acceleration to render video, animations, and complex page layouts. If the GPU driver is unable to properly process these tasks, it may result in blackouts, flickering, or other visual anomalies.

Option A) is correct because updating or reinstalling the graphics driver resolves driver-related display issues. The technician should check Device Manager for GPU errors, update the driver from the manufacturer’s website, or roll back to a previous stable driver if problems began after a recent update. Additionally, disabling hardware acceleration in the browser can prevent blackouts while maintaining usability. Ensuring Windows is fully updated helps maintain driver compatibility and stability.

Option B) Low hard drive space affects system performance and file caching but does not directly cause intermittent black screens. Temporary display issues are typically unrelated to storage.

Option C) Incorrect screen resolution may distort images or reduce clarity but does not cause temporary blackouts or flickering in web browsers. Resolution issues are static and predictable, unlike driver-related display problems.

Option D) Disabled firewall affects network security but does not interfere with the GPU or browser rendering. Black screens are unrelated to firewall configuration.

After driver updates and configuration adjustments, the technician should test multiple browsers and applications to confirm resolution. Monitoring GPU usage and temperature ensures hardware integrity. Proper driver maintenance ensures stable visual performance, prevents disruptions, and maintains an optimal user experience.
