A desktop begins throwing application errors immediately after an overnight Windows update installed. The system otherwise boots and runs normally. Which action should the technician try FIRST, as the least disruptive fix?
- APerform a Reset this PC, keeping personal files
- BRun bootrec /rebuildbcd from the Command Prompt
- CReinstall Windows from bootable media
- DUninstall the recent update from Settings > Windows Update > Update history
Show answer & explanationAnswer & explanation
Correct answer: D. Uninstall the recent update from Settings > Windows Update > Update history
Since the symptom appeared right after an update and the system still boots, uninstalling the specific update is the least disruptive fix and directly targets the likely cause. More drastic recovery options should only be used if this fails.
Why the other options are wrong
- A. More disruptive than necessary when the problem is isolated to a recent update.
- B. bootrec /rebuildbcd fixes boot configuration issues, not application errors after an update.
- C. Full reinstall is excessive for a single problematic update.
Uninstalling a Windows Update
Removing a recently installed update via Settings > Windows Update > Update history > Uninstall updates to resolve issues introduced by that update.
- Least disruptive first step for post-update issues
- Located in Update history in Settings
- Should precede System Restore or Reset this PC
