After an update to Windows 11 10.26220.5790 a Windows.old folder appeared in the Local Disk C: root folder, which actually carries all the data in the C: drive. Even though it is compressed, it takes a lot of space in my drive (approx. 60 GB), and I can't delete it. I think it is a back-up, but how to delete it to free up space? Thank you
