2] Perform SFC Scan

After uninstalling a third-party app, it is required of us to restart our PC. However, very few follow this standard practice. As a result, some leftover files remain on the device and keep interacting with the system files. Over a period of time, such files become corrupted to such an extent that you can’t update your operating system.

Similarly, when there are some or more missing files, this may also result in updates failing on Windows 11/10 PC. To solve this issue then, one must use the SFC tool. The System file checker utility will find the underlying causes and try to fix them if possible. Here’s how to run this command-line program.

sfc /scannow

SFC/Scannow

Note: At times, such errors may also occur when the device drivers haven’t been updated for a long time. One may fix this issue simply by reinstating optional updates or using DriverFix

4] Use System Restore Point

In case you do have created a system restore point sometime back in the past, you may use that right now. If you hadn’t generated any system image backup right then, skip this method, and proceed to the next one. Here’s how to use system restore point –

  • To make this solution work, ensure logging into your device as an administrator. 
  • Press Win + R to launch the Run dialog box.
  • Type “rstrui” in the text field, and hit OK.
