Hi, I just want to add what I prefer to use. I use Ccleaner to remove windows.old.
Ccleaner is a free program
In Ccleaner, on the left side, under Advanced section, there is "Old Windows Installation", check that box and click Analyze, then click Run Cleaner.
That will remove windows.old.

Adding: I think you can reinstall CPUZ. I had my Speccy removed after the install. Reinstall brought it back.

I may check ccleaner. I tried to remove windows old and can't. My problem with Disk Cleanup is it even wants to remove device driver packages. I can uncheck it but why is it several GB?

I did it using an elevated cmd prompt...same as removing WS and BT files.

takeown /F C:\Windows.old\* /R /A
icacls C:\Windows.old\*.* /T /grant administrators:F
rmdir /S /Q C:\Windows.old\

Disk Cleanup can remove most of that. You have to click the "clean up system files" button.

+1, and it's a lot easier than using all of those commands.

do a disk clean up and select clean system files

I thought that was what I said in post 2

Windows.old Folder - Delete in Windows 10 - Windows 10 Forums

This thread had a lot of helpful information, however I still couldn't resolve my issue with my windows.old file not deleting. I just wanted to share this thread in case other people were also having difficulties trying to delete their windows.old file.

My main issue is that the system thinks the folder is in use and won't allow me to delete it. The files in use are "intcdaud.sys"

My post #14 worked for me. Also, DiskCleanup will NOT remove the $Windows.~WS files, but my 3 command lines that you put in an elevated Command prompt will...for me anyway. Just be sure to change the directory names.
