A desktop begins throwing application errors immediately after an overnight Windows update. The user reports that the system was working perfectly before the update. Which of the following is the MOST appropriate first step to resolve this issue?
- AUninstall the recently installed Windows update.
- BRestore the system to a previous System Restore point.
- CPerform a clean reinstallation of Windows.
- DRun 'sfc /scannow' from an elevated command prompt.
Show answer & explanationAnswer & explanation
Correct answer: A. Uninstall the recently installed Windows update.
When system problems arise immediately after a Windows update, the update itself is the most likely culprit. Uninstalling the update is the most direct and least intrusive first step to revert the system to its previous working state.
Why the other options are wrong
- B. System Restore is a valid option, but uninstalling the specific update is often a more precise and faster solution if the update is clearly identified as the cause.
- C. A clean reinstallation is a drastic measure and should only be considered as a last resort after less intrusive troubleshooting steps have failed.
- D. While 'sfc /scannow' can address corrupted system files, the issue is directly linked to a recent update, making uninstalling the update a more targeted first approach.

- Accessed via Settings > Windows Update > Update history > Uninstall updates.

- Allows the system to revert to its state before the problematic update was applied.
