    I upgraded an old notebook from Windows 7 to Windows 10 and found this Windows.old folder with 30.2 GB of disk space!
    Mine was almost that big. 26GB and the disk cleanup method took care of it.

    Hi Shawn,

    We meet again. Unlocker deletes everything in Windows.old Folder except for the file IntcDAud.sys. One can rename and move the file through Unlocker but can't delete it (says file being used by some other Program) even on reboot. Maybe if UEFI Bios are temporarily changed into Legacy it might delete on reboot but I haven't tried it.

    Hello Peter, and welcome to Ten Forums.

    Personally, I wouldn't worry about it since it's that small now.

    If you're determined, you could see if the free program Unlocker may be able to delete the folder. :)

    Hello Amarnath,

    It's good to see you. If you haven't already, you might also take ownership of the Windows.old folder and all contents, and try again. :)

    I attempting to copy that folder and files to my other backup F: drive, and it had many data files which would not copy to it, so I just delete that fold on my Drive F:

    Would there normally be file in the "windows-old" folder that could not be copied. ?

    My up grade to windows 10 seems to all be OK, or at least everything I have used seems to be OK.
    tks, Cliff M.

    Hello Cliff,

    If you don't need anything from the Windows.old folder, then it's safe to delete using an option in the tutorial. :)
