How to Fix Windows Update Not Working on Windows 11 (7 Proven Fixes)

Windows Update not working on Windows 11? Use these 7 proven fixes to clear stuck updates, fix error codes, and get protected again — no tech skills needed.

Introduction

Windows Update is stuck. The progress bar hasn’t moved in an hour, you’re seeing a cryptic error code, or the same update keeps failing in a loop. It’s one of the most frustrating problems a Windows 11 user can face — especially when you know those updates include critical security patches.

The good news: Windows Update not working on Windows 11 is almost always fixable without reinstalling Windows. The cause is usually a corrupted download cache, a stalled background service, or a clock sync issue — and every fix below uses tools already built into Windows 11, no downloads needed.

Quick Answer

To fix Windows Update not working on Windows 11, open Settings > Windows Update and click Retry. If that fails, run the built-in Windows Update Troubleshooter (Settings > System > Troubleshoot > Other troubleshooters). For persistent failures, stop the Windows Update service, delete the files inside C:WindowsSoftwareDistributionDownload, restart your PC, and try again. This clears the corrupted cache that causes most stuck or looping updates.

Why Windows Update Fails in Windows 11

Windows Update depends on background services, a local download cache, and a live connection to Microsoft’s servers. Any link in that chain can break:

  • Corrupted update cache — partially downloaded files confuse the updater.
  • Stopped Windows Update service — it sometimes crashes silently.
  • Not enough disk space — updates need 5–10 GB free to download and unpack.
  • Wrong system date or time — causes Microsoft’s server authentication to fail.
  • Paused updates — Windows 11 lets you pause updates for up to 5 weeks; it’s easy to forget.

7 Fixes for Windows Update Not Working on Windows 11

Fix 1: Retry and Check Your Internet Connection

A dropped connection mid-download is a surprisingly common culprit.

  1. Open a browser and confirm you’re connected to the internet.
  2. Go to Settings > Windows Update.
  3. Click Check for updates or Retry.

If your connection keeps dropping, see our guide on fixing slow internet on Windows 11 first.

Troubleshooting tip: Switch from Wi-Fi to a wired Ethernet cable if possible. Wi-Fi drops during a large download often corrupt the update file.

Fix 2: Run the Windows Update Troubleshooter

This built-in tool automatically detects and repairs the most common update problems.

  1. Open Settings (Win + I).
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update and click Run.
  4. Follow the on-screen prompts.
  5. Restart your PC, then try updating again.

Pro tip: Even if the troubleshooter says it “couldn’t fix the problem,” it often silently repairs a blocked service. Always retry Windows Update after running it.

Fix 3: Check That Updates Aren’t Paused

  1. Go to Settings > Windows Update.
  2. Look for a “Resume updates” button near the top.
  3. Click it if it’s there, then click Check for updates.

This takes 30 seconds and is easy to miss.

Fix 4: Clear the Windows Update Cache

Corrupted files in the update cache are the single most common cause of stuck or looping updates. Clearing them forces Windows to download a clean copy.

  1. Press Win + R, type services.msc, and press Enter.
  2. Find Windows Update, right-click it, and choose Stop.
  3. Do the same for Background Intelligent Transfer Service (BITS).
  4. Open File Explorer and navigate to C:WindowsSoftwareDistributionDownload.
  5. Press Ctrl + A to select all files and delete them. Leave the folder itself in place.
  6. Return to Services, start Windows Update and BITS again.
  7. Go to Settings > Windows Update and click Check for updates.

Troubleshooting tip: If you see a “file in use” error when deleting, restart your PC first — then delete the files before opening any other programs.

Fix 5: Repair System Files with SFC and DISM

Corrupted Windows system files can silently break the update engine. Two command-line tools fix this.

  1. Search for cmd, right-click Command Prompt, and choose Run as administrator.
  2. Type this and press Enter:
    sfc /scannow
    This may take 10–15 minutes.
  3. When it finishes, type this and press Enter (stay connected to the internet):
    DISM /Online /Cleanup-Image /RestoreHealth
  4. Restart your PC and try Windows Update again.

Pro tip: Run SFC first, then DISM. SFC flags the corrupt files; DISM downloads clean replacements from Microsoft’s servers. The order matters.

Fix 6: Correct Your System Date and Time

An incorrect clock causes Windows Update’s security handshake with Microsoft’s servers to fail — often with no useful error message.

  1. Right-click the clock in the taskbar and choose Adjust date and time.
  2. Turn on Set time automatically and Set time zone automatically.
  3. Click Sync now.
  4. Try Windows Update again.

Fix 7: Free Up Disk Space

Windows Update can silently fail if there isn’t enough free space to unpack the update.

  1. Go to Settings > System > Storage.
  2. Click Temporary files and select what can be safely removed.
  3. Click Remove files.
  4. Search for Disk Cleanup in the Start menu, run it, and check Windows Update Cleanup.

Troubleshooting tip: If your drive is nearly full, move large files (videos, downloads) to an external drive or cloud storage before retrying the update.

Which Fix Should You Try First?

Fix Best For Time Needed Difficulty
Retry / Resume Paused updates or minor glitches 1 min Easy
Troubleshooter Most common errors 5 min Easy
Date/time sync Auth errors with no clear cause 2 min Easy
Clear update cache Stuck or looping updates 10 min Moderate
Free disk space “Not enough space” errors 10–15 min Easy
SFC + DISM Persistent error codes 30–60 min Moderate

Common Mistakes to Avoid

  1. Turning off the PC mid-install. Interrupting an update that’s actively installing (not just downloading) can corrupt Windows. Watch for drive activity before giving up.
  2. Ignoring error codes. Codes like 0x80070002 or 0x800f0922 each point to a specific fix on Microsoft’s support site. Don’t skip them.
  3. Deleting the SoftwareDistribution folder itself. Only delete the files inside SoftwareDistributionDownload. The folder must remain.
  4. Updating over a metered connection. Windows 11 blocks large updates on metered connections (mobile hotspots). Go to Settings > Network > your connection and disable “Metered connection” temporarily.
  5. Skipping restarts. Most fixes only take effect after a full reboot. Don’t assume a fix failed just because you haven’t restarted yet.
  6. Using third-party “PC optimizer” tools. Many of these disable Windows Update services. Check Services.msc and confirm Windows Update is set to Automatic (Delayed Start).

Frequently Asked Questions

Why does Windows 11 say “Update failed” with no explanation?

The most likely cause is a corrupted update cache or a stopped service. Run the Windows Update Troubleshooter first, then try Fix 4 (clearing the cache) if the troubleshooter doesn’t resolve it.

How long should a Windows 11 update take?

Security updates typically take 5–20 minutes. Major feature updates can take 30–90 minutes depending on your PC and internet speed. If the same percentage hasn’t changed in over 2 hours with no drive activity, a restart is safe.

Is it safe to skip Windows Updates?

Short term, yes. Long term, no — especially security patches. Unpatched systems are actively targeted by malware. Update as soon as you can fix the error.

What does Windows Update error 0x80070005 mean?

It’s a permissions error, usually caused by a third-party antivirus blocking the update. Temporarily disable your antivirus, retry the update, then re-enable it. If that works, add Windows Update to your antivirus exclusions.

Can I manually download Windows 11 updates?

Yes. Visit the Microsoft Update Catalog (catalog.update.microsoft.com) and search for the KB number shown in Windows Update. You can download and install it directly as a workaround while you troubleshoot the automatic updater.

Why does Windows Update keep restarting and never finishing?

This restart loop is almost always a corrupted cache (Fix 4) or broken system files (Fix 5). Run both fixes in sequence, then do a clean restart.

Will clearing SoftwareDistribution delete my personal files?

No. It only removes Windows Update’s temporary download files — not your documents, photos, or installed apps. Nothing personal is affected.

Conclusion

Windows Update not working on Windows 11 is almost always fixable with the tools Windows already gives you. Start with the Troubleshooter and cache clear (Fixes 2 and 4) — those two steps alone solve the majority of cases. For stubborn failures, SFC and DISM (Fix 5) go deeper and repair the system files that block updates from completing.
