Stuck on 'Getting Windows ready' or 'Working on updates'

Symptoms

  • Screen shows a percentage or generic progress message
  • Percentage hasn't moved in 45+ minutes
  • Happens right after a scheduled or manual update restart
  • PC feels warm but otherwise unresponsive

Likely causes

  • CommonLarge or complex update still genuinely processingFeature updates in particular can legitimately take one to three hours on slower drives.
  • CommonUpdate installation actually failed or hungSome updates stall partway through due to a conflict or corrupted download.
  • PossibleSlow mechanical hard drive struggling with update file operationsUpdates involve heavy disk activity that a slow drive handles poorly.
  • PossibleThird-party antivirus interfering with update installationSecurity software can lock files the updater needs to modify.
  • PossibleInsufficient free disk spaceUpdates can stall or fail if there isn't enough room to stage files.

What to do

  1. Watch the drive activity light (if visible) or listen for disk activity; if it's still working, give it up to 2–3 hours before intervening, especially on a hard drive rather than SSD.
  2. If there's been absolutely no activity or change for over an hour, force a shutdown by holding the power button 10 seconds.
  3. Power back on; Windows will often detect the failed update and roll it back automatically, which can also take a while but should complete.
  4. Once you reach the desktop, free up disk space (aim for at least 20GB free) before letting updates try again.
  5. Temporarily disable third-party antivirus, then manually check for updates again through Settings > Windows Update.
  6. If it stalls again, boot into Recovery Environment and use 'Uninstall Updates' under Advanced options to remove the problematic update.
  7. Check Windows Update history afterward for a specific error code to search for a known fix for that update.

When to call a pro

If updates repeatedly fail and roll back with the same error, or the drive is very old, have a professional check drive health and consider an SSD upgrade to speed up update reliability.
