Solving Windows Update Failures: A Step-by-Step Guide

Your computer has been "installing updates" for the past hour. The progress bar is stuck at 35%. Or maybe you keep getting an error message every time Windows tries to update. Sound familiar?

Windows Update problems are incredibly frustrating. You know updates are important for security, but when they fail or get stuck, it feels like your computer is holding you hostage.

In this guide, we'll walk through the most common Windows Update problems and show you how to fix them step-by-step.

Common Windows Update Problems

Update Stuck at a Percentage

The progress bar sits at the same number for hours—27%, 35%, 91%—with no movement.

Error Codes

You see messages like "Update failed" with error codes like 0x80070002, 0x8024402F, or 0x800F0922.

Endless Checking for Updates

Windows says "Checking for updates..." but never actually finds or installs anything.

Update Downloaded But Won't Install

The update downloads successfully, but fails when trying to install.

Why Windows Updates Fail

1. Corrupted Update Files

Sometimes the update files Windows downloaded are corrupted or incomplete, causing the installation to fail or get stuck.

2. Not Enough Disk Space

Windows Update needs free space to download and install updates. If your hard drive is nearly full, updates will fail.

3. Software Conflicts

Third-party antivirus programs or other software can interfere with Windows Update.

4. Corrupted System Files

If Windows system files are corrupted, updates can't install properly.

5. Background Processes Interfering

Other programs running in the background can prevent Windows from installing updates.

How to Fix Windows Update Problems

Fix 1: Restart Your Computer

This sounds too simple, but restarting can fix many update issues. If an update appears stuck, wait at least 2-3 hours before forcing a restart (some updates genuinely take that long).

Fix 2: Run Windows Update Troubleshooter

Windows has a built-in tool to fix update problems:

1. Go to Settings > Update & Security > Troubleshoot
2. Click Additional troubleshooters
3. Select Windows Update and click Run the troubleshooter
4. Follow the prompts and let it fix any issues it finds
5. Restart your computer and try updating again

Fix 3: Free Up Disk Space

Make sure you have at least 10-20 GB of free space:

1. Open File Explorer and click on This PC
2. Right-click your C: drive and select Properties
3. Click Disk Cleanup
4. Check boxes for Temporary files, Downloads, and Windows Update Cleanup
5. Click OK to delete

Fix 4: Reset Windows Update Components

This manually resets the Windows Update service:

1. Type cmd in the search bar
2. Right-click Command Prompt and select Run as administrator
3. Copy and paste these commands one at a time (press Enter after each):

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

4. Restart your computer
5. Try Windows Update again

Fix 5: Update Manually from Microsoft Catalog

If a specific update keeps failing:

1. Note the update KB number (like KB5012345)
2. Go to Microsoft Update Catalog website
3. Search for the KB number
4. Download the update for your Windows version
5. Run the downloaded file to install manually

Fix 6: Check for Corrupted System Files

Run the System File Checker:

1. Type cmd in the search bar
2. Right-click Command Prompt and select Run as administrator
3. Type sfc /scannow and press Enter
4. Wait for the scan to complete (20-30 minutes)
5. Restart and try updating again
