Yes I agree, especially considering we can't find any fix for this online other then to just "delete" it. Either way, that would be my bet, sometimes deleting a file path corrects the issue, without the need to reinstall.
I am assuming you already sent feedback to microsoft about this problem? Maybe if you leave your email they will email you indicating why this happens, as it seems even the almighty google doesn't have the answer!
Anyway, good luck, hopefully someone else comes along that was more help then I was!
