Microsoft forums no help at all :
They're all mystified. They posted to Microsoft, Kaspersky, Avast, and How-To Geek Forums, and no help from any of them. All scans return clean results. It's unlikely to be a rootkit.
it doesn't appear to be malicious or external. Its Windows being a dumb ***. Or there's a genius reason for it and I just don't get it..
yea checked out all those forums also...seems to be a re-occuring theme with anyone using win8, others have posted they re-imaged and then without hooking up there lan are still getting it so looks like its OS problem....
