How to Fix Windows Update Stuck at 0 Percent

Windows Update stuck at 0 percent can be confusing, especially when your computer appears to be doing nothing for a long time. This problem usually has simple causes, and in most cases, you can fix it without reinstalling Windows.

Why Windows Update Gets Stuck at 0 Percent

Windows Update may freeze at 0 percent due to:

• Slow or unstable internet connection
• Corrupted update cache
• Background services not running
• Insufficient disk space
• Temporary system glitches

Understanding the cause makes troubleshooting much faster.

How to Fix Windows Update Stuck at 0 Percent

Step 1: Wait at Least 10–15 Minutes

At 0 percent, Windows is often preparing files in the background.

• Make sure your PC is connected to power
• Avoid restarting immediately

If nothing changes after 15 minutes, move to the next step.

Step 2: Restart Your Computer

1. Click Start → Power → Restart
2. Let Windows boot normally
3. Try running Windows Update again

This clears temporary system issues.

Step 3: Check Your Internet Connection

• Switch to a wired connection if possible
• Restart your router
• Disable VPNs temporarily

Windows Update requires a stable connection to start downloading.

Step 4: Run Windows Update Troubleshooter

1. Press Windows + I → System
2. Select Troubleshoot → Other troubleshooters
3. Run Windows Update troubleshooter

Windows can automatically detect and fix common update problems.

Step 5: Restart Windows Update Services

1. Press Windows + R, type services.msc, and press Enter
2. Restart the following services:
   • Windows Update
   • Background Intelligent Transfer Service (BITS)
3. Set both services to Automatic

Step 6: Clear Windows Update Cache

1. Open File Explorer
2. Go to:

   C:\Windows\SoftwareDistribution

3. Delete all files inside the folder
4. Restart your PC and try updating again

This removes corrupted update files.

Alternative Solutions If the Update Still Doesn’t Start

• Free up at least 10 GB of disk space
• Install updates manually from Microsoft Update Catalog
