220-1102 Question 195
Single answerUninstallation processA Windows 11 user reports that a recently installed PDF utility causes frequent application crashes. The utility still appears in Settings > Apps > Installed apps, but when you try to remove it there, the process fails with an error indicating the uninstall source is unavailable. The user needs the application removed with the least risk of damaging Windows or other software. What should you do FIRST?
- A
Run the application's original installer package and choose the repair or uninstall option, then remove it normally
- B
Delete the program's folder from C:\Program Files and remove its shortcuts manually
- C
Use Task Manager to end all Microsoft services and then uninstall the application again
- D
Open Registry Editor and manually delete the application's uninstall keys
Show answer and explanation
Correct answer: A
Explanation
In Windows, the preferred uninstallation method is to use the application's supported uninstaller through Settings > Apps, Control Panel, or the vendor's installer package. When removal fails because the uninstall source is unavailable, best practice is to restore or repair the installation using the original installer and then perform a normal uninstall. This aligns with standard troubleshooting methodology: choose the least invasive corrective action first and avoid manual deletion of files or registry entries unless supported methods have failed. Microsoft and software vendors generally recommend using the product's installer/uninstaller rather than deleting program files directly, because proper removal may include registry cleanup, service removal, and Windows Installer database updates.
- A. Correct.
Correct. If the uninstall process fails because the original installation source or uninstall files are missing or corrupted, the safest first step is to rerun the original installer or installation package. Many Windows applications can repair the installation or restore the uninstall components, allowing a clean removal through the supported process. This follows best practice: use the vendor-provided uninstaller before attempting more invasive methods.
- B. Incorrect.
Incorrect. Manually deleting the application folder and shortcuts does not properly uninstall the software. It can leave behind services, registry entries, scheduled tasks, drivers, application data, and Windows Installer records. This is a common mistake because it may make the program appear gone while actually leaving the system in an inconsistent state.
- C. Incorrect.
Incorrect. Task Manager can be useful for stopping the application's own processes if they are blocking removal, but ending Microsoft services is unnecessary and potentially disruptive. The scenario specifically points to missing or damaged uninstall resources, not a service conflict. Stopping core services is not an appropriate first step.
- D. Incorrect.
Incorrect. Manually deleting uninstall registry keys is risky and should not be the first action. Although technicians sometimes use advanced cleanup methods when standard removal fails, editing the registry can make troubleshooting harder and may leave the application partially installed. It does not address the likely root cause: missing uninstall components.
