It is time to "Reset" Windows 10. You will not lose any of your files in the "Documents" folder, or on OneDrive. However, you will likely have to re-install 3rd party desktop software. You may need to visit Office.com if you are a Microsoft Office subscriber to refresh your Office installation, but all your files will already be there.
