    How to Delete Windows.old Folder in Windows 10

    information   Information
    If you performed a refresh of Windows 10, upgrade to Windows 10, or a custom install of Windows 10 on the same partition as the previous Windows installation without doing a clean install, then you will have a C:\Windows.old folder in your new installation afterwards. The Windows.old folder contains a copy of the previous Windows installation, and can be quite large in size.

    If you already had a C:\Windows.old folder in the installation that you performed a refresh, upgrade install, or a custom install on, then it may be renamed to say C:\Windows.old.(1) (older previous installation) in addition to the latest C:\Windows.old folder. The most recent previous Windows installation will always be in the C:\Windows.old folder.

    This tutorial will show you how to delete the Windows.old and $Windows.~BT folders that has been placed in the root directory of the Windows drive when you do a refresh or upgrade install of Windows 10.

    warning   Warning
    Be sure to copy any files that you may want out of the Windows.old folder before you delete it. Once deleted, they are gone.

    If you delete the Windows.old folder, you will no longer be able to go back to the previous version of Windows.

    You must be an administrator to be able to do the steps in this tutorial.

    This tutorial did not originally work when I tried it on the windows.old folder that was generated by the Win 10 9860 update. My fault was not bothering to scroll down and checking the box to delete the "previous windows install" box. I need to learn to read more and click less.

    I put Cleanmgr on my desktop in the first version. I use it daily as I also do in W-7.

    I have found that a reboot after using Cleanmgr it does help at time. It all seem to depend on what is being removed.

    deleting windows.old not working


    None of these options work on my system. Running VirtualBox with build 10049, installed on top of fresh 10041 (took over a day since I didn't allocate enough CPUs and RAM to the VM and every language on Earth was installed), and windows.old just seems bulletproof.

    The "Previous Windows Installation(s) checkbox isn't present.

    Tried removing "read only" attribute (everything is protected), tried del windows.old at cmd prompt w/admin rights, diskpart shows nothing...

    Sure would be nice to get that 5+ GB back!
