Pedro, you seem to have absolutely no grasp of this issue. Perhaps you ought to bow out and give someone with the actual solution an opportunity to weigh in? jaygourley, who is the one with this issue (same as I have) seems to understand better than you do, and has already availed himself of the obvious solution sets.
jaygourley, I am in a world of hurt, here. I am seeking to accomplish this system restore because of some recent (last few days) system event - probably a recent update from MS or another of my software packages - causing my Powerpoint to crash, constantly. Since this has never happened before the past few days, and I use Powerpoint as often as several times daily, it's not a fluke. AND, like you, in the past (as in, before my computer was tied to OneDrive, ...ugh), I have had zero issues using System Restore points.
Does ANYONE out there have a clue as to how to dissociate OneDrive ling enough for jaygourley and I to perform a system restore??? Help???
