When we run Windows Update again, it starts from the very beginning. Essentially we are deleting everything and making it as though the update never happened.
This is the folder where the downloaded update files and index record is kept. If that doesn’t work, we need to delete the Windows Update cache. This wipes the slate clean and allows Windows to start from scratch. Select the Services tab and check the box next to Hide all Microsoft Services.Check Load system services and Use original boot configuration if they are not already checked.Select Selective startup and uncheck Load startup items.Type ‘msconfig’ into the Cortana/Search Windows box and hit Enter.
