So when the NSA announced the update that needed to be sent installed to protect from MITM attacks i was not home so I asked a relative to do it for me and when I returned it said "Your device is missing important security and quality fixes." so I tried to do the cleanup image in cmd prompt but this came up. "the configuration registry database is corrupted windows 10" I haven't tried anything to extreme but if worse case scenario happens and no one can help me i'd be ok with resetting windows to protect my pc. Thank you! P.S if you have any other ideas on fixing the "Your device is missing important security and quality fixes." i'd be open to hear them thanks.
