1. Delete Previous Versions Of Windows

Sometimes when an update gets installed, the older Windows files may still stick around, clogging up the boot drive. Windows 10 does not need these files to operate correctly. So not only performing the steps below help with resolving the Windows 10 update error, but it also frees up a lot of valuable space on your boot drive, which in most instances, is an SSD if you haven’t performed the cleanup ever before. Do note, if you want or need to go back to a previous version of Windows in the future, we do not recommend you to perform these steps. Because going back to an older build after deleting these files would require you to reinstall an older version of Windows from an installation media carrying the same.
