    I did try option 4 which didn't work but I was then able to fiddle with the permissions and delete the files/ folders. Reading this thread, many people have had problems deleting the offending residual Intel driver IntcDAud.sys which stops windows.old being deleted. IntcDAud.sys is already present in the updated Windows folder so why is it frequently left behind in the windows.old folder which is then hard to delete? This is another example of sloppy software engineering but I don't know who is to blame - MS or Intel?

    I'm glad you got it sorted. I'd say it's a draw between them.

    You can check this tutorial and option 4. Keep in mind a folder above the target file may also have permissions which will not allow deletion, so keep an eye on the inheritance options.

    Coming off Creators Update, File Explorer told me Windows.old had 28.4 GB! And I believe it. Anyway, Option Four worked flawlessly. You do good work Shawn.

    Now, what about the C:\Windows10Upgrade folder. Does it go away eventually? Or is it one that needs to be left alone?

    Hello Clayton, :)

    The "C:\WindowsUpgrade" folder belongs to the installed Windows 10 Upgrade Assistant program. Uninstalling Windows 10 Upgrade Assistant from Programs and Features will remove it.

    Don't bother me to have it there, just don't know if that's one I may need again for the next major update. Or do they change with each occurrence of these major updates?

    That's how I got CU the other day. I'll just let it set there, it's not in the way of anything.

    Thanks for the responses and have a good weekend.

    I know this is old post. But again people who are facing this problem

    1. Go to start and press and hold Shift key while clicking on Restart from power options (you will see "please wait" sign with loading circle. This should take you to advanced boot options)
    2. Go to troubleshoot and select "command prompt"
    3. When you boot up choose the username you use (make sure it is administrator "anyway it will list only admin users 😂😂😂") and enter your password (if it is blank password just press to proceed)
    4. On command promp type "notepad" and press "enter"
    5. Press Ctrl+O (assuming you are on notepad screen) this should open up folder structure.
    6. You should be on system32 folder of drive "x" not confused by system drive which is "c" in most cases. You will be in x drive not system drive.
    7. From folder tree go up and enter to your system drive (drive c in most cases)
    8. From there select windows.old or windows.old(1) according to you
    9. Press Shift+del and wait till it prompts to delete (it will take time according to number of files you are deleting cause it needs to gather information about them)
    10. Press yes on deletion prompt and wait (the window may freeze. Don't worry it should be if you are deleting large folder. When it gets deleted you won't see the folder on that screen.)

    Note; you should be able and will delete the file on that screen cause you were using drive x as boot drive and system drive is just acting like removable storage.

    Good luck and have fun. 😊😊😊😊

    Hi, I rather let Windows delete Windows.old folder on its own. I upgraded from 1607 to 1703 ten days ago (in a few hours), using the Upgrade assistant. Is it 10 days or 30 days that Windows waits before deleting this folder and its contents?

    Hello Bo, :)

    Windows will automatically delete the Windows.old folder after 10 days since the upgrade.
