Auto Update Problem

l have a weird issue, l dont have problems updating manually... tho l had to change some setting to the realtime scanning due to windows update issues (l had to use autopatcher because windows 8.1 having issue downloading updates), however lve had to manually update windows since because the update options off general settings are all greyed out, essentially meaning auto update is turned off and l cant work out how to turn it back on because none of the options on the page are editable.

l will note however, l am looking into downgrading.. the hardware is fine but windows 8.1 its total and utter pants.
