Windows updates are essential for security and performance, but sometimes the update process gets stuck. Many users report Windows Update stuck at 0%, stuck at 100%, or freezing at a certain percentage for hours.
I recently faced this issue while updating a Windows 11 laptop. The update stayed at 100% for a long time with no progress. After checking system activity and applying a few safe fixes, the update completed successfully without reinstalling Windows.
In this guide, I’ll explain why Windows updates get stuck and share step-by-step solutions that actually work for both Windows 10 and Windows 11.
Is It Normal for Windows Update to Get Stuck?
Yes, sometimes it is.
Windows updates may appear stuck when:
- Large files are being processed in the background
- System files are being configured
- Drivers are being updated silently
Depending on your system speed, an update can stay at the same percentage for 30 minutes to 2 hours.
However, if there is no disk or CPU activity for a long time, the update is likely stuck.
Common Reasons Why Windows Update Gets Stuck
1. Slow Internet Connection
Windows downloads update files in the background. An unstable or slow connection can cause the update to freeze.
2. Corrupted Update Cache
Old or incomplete update files can block new updates.
3. Low Disk Space
Windows needs free space to unpack and install updates.
4. Driver Conflicts
Outdated or incompatible drivers may interrupt the update process.
5. Antivirus or Firewall Interference
Some security software blocks system changes during updates.
What to Do Before Trying Fixes
Before applying advanced fixes:
- Wait at least 2 hours
- Check if the hard drive light is blinking
- Avoid force shutdown unless absolutely necessary
If there’s no progress after waiting, continue with the fixes below.
Step-by-Step Fixes for Windows Update Stuck Issue
Method 1: Restart Your PC Safely
If the update is stuck for hours with no activity, a restart is often safe.
How to do it:
- Hold the power button for 10 seconds
- Turn the PC back on
- Windows usually resumes or rolls back safely
In most cases, Windows recovers without data loss.
Method 2: Check Internet Connection
Ensure your internet connection is stable.
Try this:
- Restart router
- Switch to a wired connection if possible
- Disable VPN temporarily
Windows Update performs better on stable connections.
Method 3: Run Windows Update Troubleshooter
Microsoft provides a built-in tool to fix update issues.
Steps:
- Open Settings
- Go to System → Troubleshoot
- Select Other troubleshooters
- Run Windows Update
This tool fixes common update errors automatically.
Method 4: Free Up Disk Space
Low disk space is a major cause of update failure.
Recommended free space:
- At least 15–20 GB on the system drive
Delete temporary files, uninstall unused apps, and empty the Recycle Bin.
Method 5: Clear Windows Update Cache (Safe Method)
This removes corrupted update files.
Steps:
- Press Windows + R, type
services.msc - Stop Windows Update service
- Open
C:\Windows\SoftwareDistribution - Delete all files inside
- Restart Windows Update service
- Restart your PC
Windows will re-download fresh update files.
Method 6: Disable Antivirus Temporarily
Some antivirus programs interfere with updates.
What to do:
- Temporarily disable third-party antivirus
- Run the update again
- Re-enable antivirus after completion
Do not leave antivirus disabled permanently.
Method 7: Update Drivers Manually
Outdated drivers can block updates.
Check especially:
- Graphics drivers
- Network drivers
- Storage drivers
Updating these can help Windows updates complete smoothly.
When Should You Reset or Reinstall Windows?
Only consider this if:
- Update fails repeatedly
- System crashes frequently
- None of the above fixes work
Always back up important data first.
FAQs
How long should I wait if Windows Update is stuck?
Wait at least 2 hours before taking action.

It can happen in both Windows 10 and 11.
Final Thoughts
If your Windows Update is stuck at 0% or 100%, don’t panic. In many cases, the update is still working in the background.
From my experience, clearing the update cache and running the built-in troubleshooter resolved the issue without reinstalling Windows.
