Clean up system files
Warning: If you choose to delete the $WINDOWS.~BT folder on Windows 10, you won’t be able to downgrade to the previous build of Windows 10 or previous version of Windows your PC had installed. The option to roll your PC back at Settings > Update & Security > Recovery will vanish.
However, Windows 10 automatically deletes these files after ten days anyway.
