Found a couple of 3 and 4 yr old threads on this system restore problem. Both pointed at Kaspersky or something called Tuneup Utility. I haven't had either on this laptop and, honestly I don't know how long I've been without System Restore. I have several macrium free images I can restore to, but now and then it's nice to be able to go back a day or two to remove something. Today, I wanted to do just that and System Restore is grayed out and I got a popup saying I had an error 0x81000203. After prowling the web and trying all sorts of remedies, I've about given up so figured I'd try here. I've never used Kasperky, and never heard of the Tuneup Utility thing. It isn't a major calamity, but is annoying in that everything else is running well on this machine, Win 10 Pro, 64 bit, HP 355G2 laptop with 8G RAM.
