Thank you. I've captured all of your last response to a file so I can refer to it when I need it. It has been a while since I did a disk cleanup, and the specific method you recommend makes sense.
I've spent this morning using something called Windows 10 Update Assistant to bring my OS up to date. It checked the system and advised me that my OS was out of date, and then gave me an opportunity to bring it up to date. It has already completed the somewhere
around 4 gig download in two hours (Satellite connection) and is now 84% into the update. If this does what it seems to be doing, updating my OS to the latest version, I may leave Windows Update disabled and just check back from time to time to see what Windows
10 Update Assistant) has to offer. The two tools seem to be doing the same thing, but the Assistant seems to be much more reliable at doing it.
Again, thanks for your help.
