  • Windows.old is typically automatically deleted in 10 days with the latest versions of Windows.

    It used to be 30 days with older windows versions.


    This is the method using command line:

    takeown /F "C:\Windows.old" /A /R /D Y

    icacls "C:\Windows.old" /grant *S-1-5-32-544:F /T /C /Q

    RD /S /Q "C:\Windows.old"

    There are multiple methods to delete windows.old with text and images in this link:

    Disk cleanup is typically the method with the most familiarity.

    So you can manually delete now or wait 10 days for automatic deletion.

  • Hi Amin2234.

    You can delete that folder, but you have to remember that you will no longer be able to use the recovery options to rollback to a previous Windows 10 version.
    If you want to delete that folder, run the Windows Disk Cleanup tool and select the "Previous Windows installations(s)" check box.

    Bye.

  • Hello Amin,

    As the others have posted, you get the Windows.old folder when you perform a refresh or upgrade of Windows 10.

    The Windows.old folder contains a copy of your previous installation. If you delete the Windows.old folder, you will not be able to use the "Go back to previous version of Windows" feature if needed.

    The Windows.old folder will automatically be emptied or deleted in 10 days after the refresh or upgrade by default.

    The tutorial below will show you some options on how to delete the Windows.old folder.

  • Hi,

    Yes, you can. Deleting Windows.old folder will not affect your PC. The Windows.old folder contains all the files and data from your previous Windows installation. You can use it to restore your system to the old version of Windows if you don’t like the new version. If you find that you no longer have any use for it you can also remove/delete the Windows.old folder manually.

    You can use the Windows Disk Cleanup tool to delete the folder.

    Just follow the steps provided by Webmasterroot.

    You can also use this tool to delete other unnecessary files taking up space on your system drive.

    Best regards.
