In such a situation, please try the basic steps which are followed when a Windows Update fails to install. Other than those steps, a few of the following could be tried as well:
1] Delete the folder $WINDOWS.~BT
- Make Windows show Hidden files & folders. To do this, open the File Explorer and among the tabs on the top, select the View tab.
- Check the option for hidden files as in the image below.
- Search for the folder $WINDOWS.~BT in the C: drive. Once you find it, delete it.
