I may have a system back up, however it may be couple years old. It was taken almost immediately after moving from Win 8 to Win 10.
There seem to be only 4 restore points: from 12/12/2016, 7/21/2017. 7/28/2017 and 8/6/2017.
I can get a new disk and load the new windows 10 upgrade on that disk. However, I will need to install all my software all over again. Also there will the issue of migrating my license key to the new install.
