Select the keyboard shortcut Win+X, and click Command Prompt (Admin) on the drop down menu. Type cd and press ENTER. Type or copy and paste the command "DISM.exe /Online /Cleanup-image /Scanhealth " without the quotes and press the ENTER key. Type or copy and paste the command " DISM.exe /Online /Cleanup-image /Restorehealth" without the quotes and press the ENTER key. Make sure you include the spaces where indicated. These procedures can take a long time to complete so you need to be extremely patient. Type exit when it completes, press the ENTER key and restart the computer.


If you get an Error 87 response recheck the command you entered.


Please upload a copy of the DISM log file as a shared file to your OneDrive and post a link here.


You may need to show hidden files. Use the keyboard shortcut Win+X to access Control Panel, Folder Options and select View, Advanced Settings. Verify that the box before "Show hidden files and folders" is checked and "Hide protected operating system files" is unchecked. You may need to scroll down to see the second item. You should also make certain that the box before "Hide extensions for known file types" is not checked.


Open File Explorer (keyboard shortcut Win+E) and locate your C partition. Expand C along the file path C>windows>logs>DISM>dism.log. To expand C click the arrowhead to left of C and repeat with windows and sub-folders as necessary.
