Scan for malware

Manually restore Windows Update services through the Registry Editor

Reset your computer

4. Find "Windows Update" and click run on the right

The entire troubleshooting process may take a while, and after completing the above steps, CTOnews.com users can try to install the update on Windows again.

Users running SFC and DISM scanning CTOnews.com can solve this problem through SFC and DISM. The SFC (system File Checker) scan detects any corrupted system files and attempts to repair them, while the DISM (deployment Image Services and Administration) scan checks for any corrupted Windows components that need to be repaired.

Both scans are relatively fast and straightforward processes that do not require any advanced technical knowledge. All CTOnews.com users need to do is to open the command prompt as an administrator and follow these steps:

1. Open the start menu, search for CMD, and right-click to run the command prompt as an administrator

two。 Enter the "sfc / scannow" command in the pop-up window and press enter

This process takes a while, and if you like, you can do other things while the system scans the data. The scan is complete. Please try to update Windows again.

1. Open the start menu, search for CMD, and right-click to run the command prompt as an administrator

two。 Type the following command and press enter to execute. Notice that each "/" is preceded by a space.

DISM.exe / Online / Cleanup-image / Scanhealth # scan all your system files and compare them with official system files DISM.exe / Online / Cleanup-image / Restorehealth # restore those different system files to the system's official source files, which takes about the same time as reinstalling. after the scan is complete, please try to update Windows again to see if the problem has been solved.
