Update for all. Thank you for your interest and suggestions. Here are my responses and where things stand now.
In my second post (see above) I corrected the first to say that I made a mistake. The RP’s on my Win7 computer were not being erased.
I have accepted the solution that it was my fault because somehow wipe free space drives on a new install of Cc got checked in settings and should not have been. When I unchecked the box, the box actually went away. I really don’t remember checking it, but this whole transition from Win7 to Win10 has this old lady so frazzled I just don’t know.
I never checked or used the drive wiper in tools. I at least know never to do that.
The space for SR is on my C drive which is an SSD drive. I have never used Win10 defrag tool or any other defrag tool. I don’t think you defrag SSD drives. My D drive is an HDD drive and I have not used defrag on that either. According to Win10 the program Optimizes the SSD and Defrags the HHD automatically weekly. (Built in Defrag and Optimize App)
I did reduce the allocated space for SR to 15% or 35 GB. If it happens again, I will reduce it further.
I really have come to the conclusion that the problem is not Ccleaner because since this started and I removed the check mark from wipe free space, I have run Cc and checked SR and all the restore points would be there. What ever happens does not seem to happen when I run Cc.
I discovered a couple things to do on line. First in Configure System Restore I clicked to disable it. The RP’s were gone anyway. Then I restarted the computer. Then I checked to turn on system restore. Then I restarted the computer again.
One online site suggested there could be corrupt files and Win10 may be erasing corrupt files from SR and that would be a good thing. So, I ran sfc /scannow and sure enough there were corrupt files on my computer and every time I made a restore point, I guess there were corrupt files in the RP.
The corrupt files had something to do with One Drive which I do not want. I have only one device, my desktop. I don’t want anything in the cloud, I want my stuff in my house. I cannot interpret the sfc log but I recognized the words “one drive” in it a lot.
I had uninstalled One Drive from Control Panel>Programs and Features. But it does not go away. When the Microsoft Office Team tech set up Office 2019 on my computer, One Drive was in Office too. I told him I did not want it, he said not to worry because nothing would go there until I sign in to it or something, but he went ahead and removed it anyway the same way I had before. Still it is on my C drive and is in Office Outlook and Office Word. It has no files in it but it won’t go away.
Well back to sfc. The report was that all corrupt files had been successfully repaired and I am ignoring One Drive which is somehow a part of Win10 and Office 2019 and it will be in my face whether I want it or not.
Finally, in the past I backed up my files and folders and a system image on an external hard drive once a month on the first of the month using the Windows Backup Program. I have no idea what I would have done if I needed to restore any of it. I did this for seven years and never needed it or used it but I had it and I guess I would have gotten someone who knew how to use it to restore my computer.
I lack the technical knowledge to restore whole or partial images or use other backup programs.
I prefer System Restore because it is easy. And I did occasionally use it.
Well I think that’s it. Thanks again to all.
PS I have tried to edit this because emojis popped up instead of the letters of my drives. I don't know why but now I just typed the letter without the : so maybe that will stop it. Just a guess.
