    CANNOT DELETE windows.old (DiskCleanup and cmd.exe methods dont work)


    I was stupid and manually tried to delete windows.old. Didn't work. So then I decided to see how to properly do it. Well apparently by manually trying to delete the files, when I tried to use diskcleanup and look for the "Previous Windows Installation" check box does not show up anywhere. I assume its because I'm an idiot and tried to delete windows.old myself manually. Hmph!!! After all that I tried doing the cmd.exe method. It ran but all files said, "Access Denied". So am I completely screwed? Do I need to completely reinstall windows now to fix this or is there some way to do this still? It takes up about 27 gigs of space so I would really like to free that up. Thank you for any advice.

    Note that Option Two in that tutorial is your 'cmd.exe method' - it says it must be an elevated command prompt. Did you try in a normal command prompt?

    There may be a driver in there that windows is still using, let it go 10 days and see if windows deletes it on its own.

    But any live Linux version should let you go in and delete it.
