No, Apolari, I was not executing from the command line. There are numerous ways to navigate to the Windows applet that creates a restore point and recovers a stored restore point.
I have not tested this issue with the latest Windows build. To test is simple though. Go to the applet that creates a restore point. Tell it to create a restore point. As soon as it reports that it has created a restore point, tell it to recover that to that restore point. If you try to restore immediately, you don't risk losing anything. If Windows successfully restores the restore point, then you don't have the problem that started this thread. The problem was (maybe is) that Windows cannot restore a restore point that it has just created.
