2. Free Up Disk Space

Windows updates often require at least 10–20 GB free for smooth installation. Low storage can cause errors.

Steps:

1. Open Settings > System > Storage.

2. Use Temporary Files to delete cache, logs, and unnecessary files.

3. Empty the Recycle Bin and uninstall unused programs.

3. Reset Windows Update Components

Corrupted update files can block installation. Resetting update components often fixes this.

Steps:

1. Press Windows + X, select Windows Terminal (Admin).

2. Stop update services by entering:

   net stop wuauserv
net stop bits
net stop cryptsvc


3. Rename software distribution folders:

   ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old


4. Restart services:

   net start wuauserv
net start bits
net start cryptsvc


5. Try updating Windows again.

This method clears corrupted update caches that commonly cause errors.

4. Check for System File Corruption

System files can prevent updates from installing correctly.

Steps:

1. Open Windows Terminal (Admin).

2. Type sfc /scannow and press Enter.

3. Wait for the scan to complete; it will repair corrupted files automatically.

4. After completion, type DISM /Online /Cleanup-Image /RestoreHealth to fix deeper system issues.

Repairing system files ensures your OS can install updates successfully.

5. Restart Windows Update Service

Sometimes the update service simply needs a restart.

Steps:

1. Press Windows + R, type services.msc, and press Enter.

2. Scroll down to Windows Update, right-click, and select Restart.

3. Check for updates again in Settings.

This resolves minor service-related errors quickly.

6. Disable Third-Party Antivirus Temporarily

Some antivirus software may block updates, thinking they are suspicious.

Steps:

1. Temporarily disable your antivirus.

2. Restart your PC.

3. Try updating Windows again.

4. Re-enable antivirus once the update completes.

Disabling antivirus temporarily is safe if you are connected to a secure network.

7. Check Your Internet Connection

A slow or unstable connection can cause update failures.

Steps:

1. Use a wired connection for reliability.

2. Restart your router and PC.

3. Check that your connection is stable using ping tests or speed tests.

4. Retry the Windows update.

Consistent connectivity ensures large update files download completely.

8. Manually Install Updates

If automatic updates fail, you can manually download and install updates.

Steps:

1. Open Settings > Update & Security > Windows Update > View update history.

2. Note the KB number of the failed update.

3. Go to the Microsoft Update Catalog website.

4. Download the update matching your system version.

5. Run the installer manually.

Manual installation bypasses potential software conflicts with the automatic updater.

9. Perform a Clean Boot

Clean boot starts Windows with minimal programs and services, reducing conflicts.

Steps:

1. Press Windows + R, type msconfig, and press Enter.

2. Go to the Services tab, check Hide all Microsoft services, and click Disable all.

3. Go to the Startup tab, open Task Manager, and disable startup apps.

4. Restart PC and attempt the update.

5. After success, restore services to normal.

Clean boot eliminates software conflicts that block updates.

10. Reset Your PC as Last Resort

If all else fails, resetting Windows keeps your files while reinstalling the system.

Steps:

1. Open Settings > Update & Security > Recovery > Reset this PC.

2. Choose Keep my files.
