2] Run SFC and DISM

You may get the error due to corrupted system files. We can repair the files using the System File Checker (SFC). This tool will scan your system files and then repair the corrupted ones. In order to do the same, open Command Prompt as an administrator and then run the following command.

sfc /scannow

Let the command run, and if it doesn’t yield any fruitful result, run the following DISM command.

DISM.exe /Online /Cleanup-image/Scanhealth

DISM.exe /Online /Cleanup-image/Restorehealth

Once your command is successful, reboot your computer and then run Windows Update and see.

3] Run Background Intelligent Transfer Services and Windows Update Troubleshooter

Run the Background Intelligent Transfer Service (BITS) Troubleshooter in the Get Help app and see. It can scan what’s wrong with the service and then provide you with a perfect solution and, in some cases, even execute the required solution. You can access it via the Get Help app or via the Windows Settings > Troubleshooters page.

If the issue is not resolved, run the Windows Update troubleshooter as BITS is related to Windows Update.

4] Clear Windows Update Path

Next up, we need to clear the Windows Update path from Registry and let the computer create them once again. We do this to ensure that you don’t get the error due to a corrupted registry. Making amendments to the registry is generally discouraged, which is why you should create a backup of the registry that can be used in adverse scenarios. Once you have created the registry backup, follow the solutions mentioned below to clear the Windows Update path.

1. First of all, launch Registry Editor.
2. Next, navigate to the following path.

   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

3. Search for WUServer and WIStatusServer.
4. You need to delete them. In case, they are not listed, you should skip this solution and move to the next one.

After deleting the file, reboot your computer and check if the issue is resolved.

5] Reset your computer

If nothing works, and if this causes your Windows Update to fail, your last resort is to reset your computer. We are not going to delete your files but reconfigure your device. So, use the Reset this PC option from Settings, making sure you opt to Keep your files, and then check if the issue is resolved.
