How to Fix Windows Update Errors

How to Fix Windows Update Errors starts with identifying why an update is failing. The problem may be an unstable internet connection, insufficient storage, corrupted download files, or a Windows component that is not working correctly. Check the error code first, restart your computer, and run the Windows Update troubleshooter before trying more advanced repairs. Many update problems can be resolved without resetting or reinstalling Windows.

This guide explains how to troubleshoot Windows Update on Windows 10 and Windows 11, including failed downloads, installation errors, updates that remain stuck, and problems that keep returning.

Quick Checks Before Fixing Windows Update

Before changing system settings, complete these basic checks.

1. Find the Windows Update Error Code

An error code can help identify the cause of a failed update.

Open Settings.
Select Windows Update on Windows 11, or Update & Security → Windows Update on Windows 10.
Open Update history.
Find the failed update and note its error code and KB number, if available.

Use Microsoft’s Windows update and installation error guide to investigate the specific code.

2. Check Your Internet Connection

A weak or interrupted connection can prevent Windows from downloading update files.

Open a browser and check whether websites load normally.
Reconnect to your Wi-Fi network or try Ethernet.
Restart your router if the connection is unstable.
Temporarily disconnect a VPN if you suspect it is interfering with the update.

Once your connection is stable, return to Windows Update and try again.

3. Check Available Storage

Windows needs enough free space to download, unpack, and install updates. The amount required depends on the update and your device.

Open Settings → System → Storage.
Check the available space on your Windows drive, usually C:.
Remove unnecessary temporary files using Windows’ built-in storage tools.
Empty the Recycle Bin if you no longer need its contents.
Retry the update.

Do not delete unfamiliar files from Windows system folders to create space. See Microsoft’s guide to freeing up drive space in Windows for safer options.

4. Restart Your Computer

Save your work, select Start → Power → Restart, and allow Windows to load fully. A restart can complete pending installation tasks and clear temporary problems that interfere with updates.

5. Run the Windows Update Troubleshooter

The troubleshooter can detect and resolve some common update problems.

On Windows 11:

Open the Get Help app.
Search for Windows Update troubleshooter.
Follow the instructions and apply any recommended fixes.
Restart your computer if prompted.
Check for updates again.

On some Windows 10 versions, open Settings → Update & Security → Troubleshoot → Additional troubleshooters → Windows Update.

For current instructions, see Microsoft’s Windows Update troubleshooter guide.

1. Fix Windows Update Download or Installation Failures

Use these solutions when an update will not download, fails during installation, or repeatedly reports that it could not be installed.

Restart the Windows Update Service

The Windows Update service manages part of the update process. Restarting it may help if the service has stopped responding.

Press Windows + R.
Type services.msc and press Enter.
Find Windows Update.
Right-click it and select Restart, if available.
If the service is stopped, select Start.
Close the window and try the update again.

If Windows displays an error when you start the service, record the message instead of changing unrelated services.

Check the Date and Time

Incorrect date or time settings can interfere with secure connections and some update operations.

Open Settings.
Select Time & language → Date & time.
Enable Set time automatically.
Check that the time zone is correct.
Select Sync now if available.
Retry Windows Update.

Install the Failed Update Manually

If one particular update repeatedly fails, you may be able to install it from Microsoft’s Update Catalog.

Open Settings → Windows Update → Update history.
Find the failed update and note its KB number.
Visit the Microsoft Update Catalog.
Search for the exact KB number.
Select the package that matches your Windows version and system architecture.
Download and run the package, following its instructions.
Restart your computer if prompted.

Do not download update packages from unfamiliar third-party websites. If the catalog does not offer a suitable package, investigate the error code before trying another installation method.

2. Fix Windows Update Errors With Specific Error Codes

Error codes can point toward likely causes, but they do not always identify a single problem. Use the following table as a starting point.

Error code	Possible cause	What to try
`0x80070005`	Access denied or permissions issue	Run the troubleshooter and investigate the specific error
`0x80070002`	Missing files or update data	Restart Windows and retry the update
`0x8007000D`	Invalid or corrupted data	Run the troubleshooter and consider clearing the update cache
`0x800705B4`	Update operation timed out	Check your connection, restart, and retry
`0x800F0922`	Installation or servicing problem	Check available storage and investigate the affected update
`0xC1900101`	Often associated with driver problems during an upgrade	Check drivers and disconnect unnecessary devices
`0x80070422`	A required service may be disabled	Check Windows Update service settings

For more detailed guidance, consult Microsoft’s Windows update and installation error documentation.

Repair Damaged Windows System Files

If basic troubleshooting does not resolve the error, damaged Windows components may be responsible. DISM and System File Checker (SFC) are built-in tools that can check and repair certain types of system corruption.

Step 1: Run DISM

Open Start and search for Command Prompt.
Select Run as administrator.
Approve the permission prompt.
Enter this command:
DISM /Online /Cleanup-Image /RestoreHealth
Press Enter and wait for it to finish.

DISM checks and repairs the Windows image used for system maintenance. It may take several minutes and may require internet access to obtain repair files.

Step 2: Run System File Checker

After DISM finishes, enter:

sfc /scannow

Press Enter and allow the scan to reach 100%. Follow any instructions displayed, then restart your computer and try Windows Update again.

These commands are useful when system corruption is suspected. They are not necessary for every update error.

For more information, read Microsoft’s guide to using System File Checker.

3. Fix Updates That Get Stuck or Keep Failing

If an update repeatedly fails after downloading, stays at the same percentage for an unusually long time, or fails again after restarting, try these targeted solutions.

Clear the Windows Update Download Cache

Windows stores downloaded update files in the SoftwareDistribution folder. If those files become corrupted, clearing the download cache can force Windows to download fresh copies.

Important: Stop the Windows Update service before clearing the cache. Delete only the contents of the specified folder, not unrelated files or other Windows system folders.

Press Windows + R.
Type services.msc and press Enter.
Find Windows Update.
Right-click it and select Stop.
Open File Explorer.
Enter this path in the address bar:
C:\Windows\SoftwareDistribution
Open the folder and select its contents.
Delete the selected contents. If Windows reports that a file is in use, do not force-delete it; check that the service has stopped and investigate the message.
Return to Services.
Right-click Windows Update and select Start.
Restart your computer if needed, then check for updates again.

Windows will recreate the necessary cache files as it checks for updates. The next scan may take longer because update files need to be downloaded again.

If you are uncomfortable deleting files manually, skip this step and use Microsoft’s troubleshooting guidance.

Reset Windows Update Components

If the troubleshooter and cache-clearing method fail, resetting the update components may help. This is an advanced step, so use it only when simpler solutions have not worked.

Back up important files before making system changes.
Open Command Prompt as administrator.
Stop the relevant services by entering these commands one at a time:
net stop wuauserv

net stop bits
Rename the update download folder:
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
Restart the services:
net start bits

net start wuauserv
Restart Windows and check for updates.

These commands stop and restart the Windows Update and Background Intelligent Transfer Service (BITS) services and rename the download cache so Windows can create a fresh one.

If a command fails, read the error message and stop rather than repeatedly running commands. A service may already be stopped, or the folder may already have been renamed. This basic reset does not reset every Windows Update component; use Microsoft’s instructions for more extensive repairs if your specific error requires them.

Check for Driver or Software Conflicts

If a major Windows upgrade fails during installation, an incompatible driver or background program may be responsible.

Try these steps:

Check your computer manufacturer’s official website for relevant driver updates.
Disconnect nonessential external drives, printers, and USB devices during the upgrade.
Review the error code for driver-related clues.
Check security software compatibility if you suspect a third-party program is interfering.

A clean boot can help identify conflicts caused by background programs, but it is not necessary for every update error. If you try one, hide all Microsoft services before disabling non-Microsoft services, and record your changes so you can restore normal startup afterward.

Check Microsoft’s Windows Update Status

Sometimes an update fails because Microsoft has identified a known problem affecting particular devices or configurations.

Visit the Windows release health dashboard and check for known issues affecting your Windows version and the update you are installing.

If Microsoft has documented a compatibility hold or known issue, follow its guidance instead of repeatedly forcing the installation.

A Related Windows Service Problem

Windows services can affect different features of your computer, although a Bluetooth service issue does not usually explain a Windows Update failure. If you are also troubleshooting Bluetooth connectivity, our ValueAllTech guide on how to restart the Bluetooth service in Windows explains how to check the Bluetooth Support Service.

Use that guide only if you are experiencing a Bluetooth problem alongside the update issue.

What If Windows Update Still Fails?

If none of these methods works, collect the details below before attempting more advanced repairs:

Your Windows version and edition.
The failed update’s KB number.
The complete error code.
Whether the failure occurs during downloading, installation, or restart.
Any relevant messages from the troubleshooter.

This information can help you identify a targeted fix instead of trying unrelated solutions.

As a last resort, consider Windows recovery options or an in-place repair installation using official Microsoft installation media. Back up important files first and follow the instructions for your Windows version. A full reset or clean installation should not be your first response to an ordinary update error.
