Purchased new Feb 16...see my post "Source Problem" posted last Saturday. This had corrupt files impossible to rectify using sfc /scannow or any dism commands. This went belly up Saturday evening and was RTM Sunday. Today received a replacement and after setting it all up to my satisfaction decided to do a scannow. This again revealed corrupt files, surely this is not a coincidence. I can only assume Bitlocker has something to do with this. Can anyone check their own computer please and post the result, it would be appreciated.
