    If able, try booting from installation media instead, then open a command prompt at boot like in OPTION ONE. This way you will be completely outside the OS.
    I tried with winpe8.1 boot usb stick and tried deleting that folder both in explorer and admn command prompt. There also in explorer I got message access denied and in cmd, got msg, You need permissions of System

    I finally managed to delete it by booting directly to a Command Prompt in the Advanced boot settings. Everything else I tried didn't work.

    Can I keep windows 10 from deleting it after a month or something like that? Or move it to an other location and direct it to that path?

    Hello Max,

    Not that I'm aware of.

    It would be best to create an image backup of the previous Windows before upgrading to restore it with.

    The Go back to previous Windows feature is just for a temporary backup in case there was a problem with the upgrade, or one didn't care for Windows 10.

    Hello
    Completely new here. I tried everything to get rid of windows.old. It didn't work or was too complicated.
    I found a much easier way to delete it: Get a program like Parted Magic which boots from disc and have a file explorer in it. Delete windows.old, thats it. Since two days I found no bugs in Win 10 because I have done this.
    Hope it helps

    I tried this but it ended with a corrupted MBR so my computer stopped working. Have it fixed but now I am hesitating to use a Linux option like

    I upgraded an old notebook from Windows 7 to Windows 10 and found this Windows.old folder with 30.2 GB of disk space!

    Take ownership of it and then run Disk Cleanup as an Admin. That worked for me.

    Gary you hit the nail with a hammer. After an upgrade some bits of Windows.old are owned by SYSTEM user and cleanmgr will not delete them. If you take ownership it works fine.
