BTY My above-mentioned C drive folder (DD... something)is not the regular folder that we can see, I think (?) only Microsoft 2nd-level tech guys are allowed to have access to this operating program and update folder in the C drive because he took me to somewhere that’s unfamiliar to me.  All of my other folders were fine except for this particular folder reaching 100% capacity from various updates. After 2 hours of cleanup, all of my prior update files were gone - even Microsoft 10 update files. Fortunately, I was able to download Proseries 24 without updating Microsoft 24H2. My computer is stuck at 46% for 24H2 so  I cancel the updates and block all future updates from Microsoft.
