Re: "possible to remove the Windows 10 update files using the Disk Cleanup utility."
Well said. I was wondering why people here seem to be asking themselves how to continue to wrestle with Windows to make it play ball.
Personally, if a company or product I do business with or buy doesn't play ball, then I don't use them or it anymore. Period. Stop wrestling with or trying to fix Windows. If it doesn't do what you want, stop living in denial. Admit it and find an alternative that does.
