No, I won't delete Windows.old.
It’s meant to allow you to revert changes if the latest update isn’t functioning properly. I recommend saving it for a short period before removing it, in case you need to roll back. It seems to be removed after about a month.
Get ready for a struggle to eliminate it. Regardless of how often I switch owners, set passwords, or adjust permissions, I still can’t remove those subfolders.
The issue is that during the disk cloning backup, Windows.old was included, which took up space. I had to delete it, but while cloning permissions were handled correctly, the folder size dropped dramatically—from 30 gigabytes to just 6 gigabytes after about two hours.
