Been monitoring this thread forever as I have this exact same problem Ox8007018b is the error. Short of reinstalling windows as a fresh install there clearly must not be a solution. That no one from Microsoft has addressed this either is deplorable.
Yes, it is deplorable that Microsoft has not addressed this issue. No, reinstalling Windows does not solve anything. I am seeking to return to prior backup point...nothing moving forward from now makes any difference. The issue occurred in the past, which can only be resolved by returning to a prior restore point, before the issue occurred. No one seems to get this...
You saved me from doing what would been a fruitless re install. For that I thank you!
I feel badly for all of us who are experiencing this critical Microsoft fail. A pity that Microsoft - with billions of dollars in the bank, and resources beyond our imaginations - cannot address this issue for its customers. Pathetic.
