Symptoms

  • Recovery screen appears specifically after an update-triggered restart
  • Options shown include Try again and See advanced repair options
  • Repeating Try again leads back to the same screen
  • PC otherwise powers on normally

Likely causes

  • CommonUpdate failed to apply correctlyAn interrupted or conflicting update installation is the most direct cause.
  • CommonDriver incompatibility introduced by the updateUpdates sometimes replace drivers with versions that don't work with specific hardware.
  • PossibleCorrupted update filesA partially downloaded or damaged update package can fail during application.
  • PossibleThird-party software conflicting with the update processCertain security or system utilities interfere with update installation.
  • PossibleInsufficient disk space during update applicationUpdates can partially apply and then fail if space runs low mid-process.

What to do

  1. Click 'Try again' once, since some update failures self-resolve on a second attempt.
  2. If it fails again, choose 'See advanced repair options' to enter the Recovery Environment.
  3. Go to Troubleshoot > Advanced options > Uninstall Updates and remove the most recent quality or feature update.
  4. Restart to confirm the PC now boots to the normal desktop.
  5. Once at the desktop, free up disk space and temporarily disable third-party antivirus before letting Windows Update try again.
  6. Check Settings > Windows Update > Update history for the specific failed update and search for any known issues Microsoft has published for it.
  7. If Uninstall Updates isn't available or doesn't work, try Startup Repair or System Restore to a point before the update as alternatives.

Tools and parts

  • Bootable Windows recovery USB drive

When to call a pro

If uninstalling the update and Startup Repair both fail to restore a working boot, a technician can perform a repair install that keeps your files while resetting system components.
