    One file left in Windows.old


    After a successful install, I used Disk Cleanup to to remove windows.old - after a good while it finished, but the folder is still there, with one file still left:
    C:\Windows.old\Windows\System32\DriverStore\FileRepository\point32.inf_x86_neutral_4c8bd195d4599eb3\ point32.sys
    the file also exists in the new windows folder which is similar but exactly the same:
    C:\Windows\System32\DriverStore\FileRepository\point32.inf_x86_4c8bd195d4599eb3\point32.sys
    The two files are identical, same SHA-256 hash.

    Initially the error was "Access Denied" so I took ownership of each folder and gave myself full control, after that, the error changed to "File is in use by another program" - Process Explorer could not find a handle to the file. Oddly, I can rename the file, which I did, to point32.xsysx but still cannot remove it. I know it's just one lousy 40KB file but it has me baffled.

    Hi, suggest you boot from a live boot CD (there's one available here - first item in Software and Apps) or even a Win 10 disk or usb if you're familiar with using the command prompt, and delete these from outside Windows.

    My experience may be different from yours, but...

    I also used Disk Cleanup to remove windows.old and it left the folder and some file in it. Being a neat freak I managed to delete the file and the folder. Then Windows 7 Backup and Restore, on the next and subsequent backups, claimed that the backup completed but there was a problem. It claimed that it could not find windows.old. So there was a reference to windows.old somewhere but I couldn't find the reference. So I created an empty folder windows.old in the expected place and backup got happy again.

    I think there is magic associated with the folder. It might be best to leave it alone.

    Good luck!

    Thanks - Yep I get that, my main source of confusion is that I can rename the file but cannot delete it. Everything I know and have read says that rename and delete permissions are not separable. Also, if it is in use, as per the error I get trying to delete, how can I rename it ?

    Windows 3.1 to Windows 10

    because *.sys is a system driver....
    the registry is pointing to the windows.old as the current source for (and loaded ) the driver...

    booting from a non-windows environment will allow you to remove the windows.old folder and upon reboot windows will use the default location for the driver - which is also present in the driverstore..

    If you are able to rename the file in windows.old folder - do so - then reboot the pc - so windows will load the default location for that driver

    Thanks for the reply - I use Acronis and Macrium, never used Windows Backup. I also cannot find any references to windows.old except that Process Explorer shows that explorer.exe has 3 handles to it. I tried setting up a cmd window with the delete command already there, killing explorer with task manager and hitting enter in the cmd window - access denied. Did you make a typo when you said that Windows 7 Backup and restore complained about windows.old ? It would seem that if there is a windows.old folder, them Windows 7 is gone ?? Have a look at my other response - "my main source of confusion"

    This is common - you need to boot (as others say) from outside windows using eg live linux drive, ms drive, or something like Macrium Rescue drive (use its file explorer)

    I understand that but still wonder why I can rename the file to anything I want, but not delete it no matter what the name is changed to.

    File will be owned by System, and not have delete rights.
