Microsoft releases a multitude of cumulative updates for Windows 10 and 11 each month. Typically, updates are automatically downloaded and installed through Windows Update; however, users may occasionally encounter various errors during the update process. For each potential error, there are tried and tested solutions suggested by users who have experienced similar issues.
Understanding why Windows Update errors occur is the first step in resolving them. Your error could be due to one of the following causes:
- Incorrect or corrupted Registry: An inaccurately modified or corrupt registry entry for wuauserv can lead to update errors, as this value is responsible for the downloading, detection, and installation of Windows updates.
- Windows Update Service not working: If the Windows Update service is disabled or stopped, it can prevent the installation of updates.
- Corrupted Software Distribution Folder: Should the contents of the Software Distribution folder become corrupted, you’ll likely encounter errors, as this folder stores the temporary update files required for installing Windows updates.
- Corrupt System Files: Corrupted system files are another common culprit as they are crucial for updating Windows. To repair any corrupted files, follow the instructions provided below.
Note that the causes of Windows Update errors are varied and not confined to the aforementioned list. Additional factors such as network issues, hardware and software incompatibility, specific bugs within an update, or other system conflicts may play a role. Identifying the precise cause of a Windows Update error in your particular case may necessitate a systematic troubleshooting approach.
1. Use the Windows Update Troubleshooter
Windows has a built-in tool specifically designed to diagnose and resolve common issues with Windows Update. The troubleshooter scans for problems and attempts automatic repairs.
- Navigate to Settings by pressing Windows + I, select Update & Security, then click on Troubleshoot.
- Click on Additional troubleshooters, locate Windows Update, and then select Run the troubleshooter.
- The troubleshooter will begin detecting problems. Follow any on-screen instructions to permit the utility to attempt fixes for identified issues.
- Once the troubleshooter has completed its process, reboot your computer to allow any changes to take effect, and then check to see if you can now proceed with Windows updates.
2. Restart Windows Update Service
Begin by restarting the Windows Update service, which is fundamental to the updating process. Ensure that the service is running correctly.
- Press Windows + R to open the Run dialog.
- Type services.msc and click OK.
- Type W on the keyboard to quickly navigate to the Windows Update service.
- Right-click Windows Update Service and select Properties.
- Set the startup type to Automatic from the dropdown menu.
- Click Apply, then click Start if the service is not running.
- Finally, click OK and verify whether the error has been resolved.
3. Reset Windows Update Registry Keys
Corrupted or incorrectly modified registry keys could be responsible for the errors. Resetting these keys to their default values is a useful step.
- Download the registry file from here to reset Windows Update registry values.
- Right-click the downloaded file and select Run as administrator.
- Click Yes to confirm the changes.
- After the process is complete, verify whether the error has been rectified.
4. Turn OFF Metered Connection

5. Clear And Rename Software Distribution Folder
The Software Distribution folder houses the Windows update files necessary for installing updates. Corruption within this folder can lead to update problems.

- Press the Windows key and search for “Command Prompt.”
- Run it as an administrator and enter the following commands:
DISM /Online /Cleanup-Image /RestoreHealth sfc /scannow
- After the scans are complete, close the terminal and recheck for the error.
