Cortana gone

Did the anniversary update and it removed Cortana, Microsoft support is useless . it is still in the all app list but when i click on it all i can do is search windows files

It has been reported already.

Start your regedit, go to

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Search

find key

BingSearchEnabled

and set it to 1. This should immediately enable your Cortana.

yep that worked, thanks!
