I have been using Windows 8 pre-release and lately it asks me for my administrative password to make software installations to my desktop PC....I used the password that I created when I installed Win 8 and it doesn't work. What is the administrative password....I only see my user account on user accounts....admin account not listed. I recently changed the email I was using for windows 8 from a verizon.net email to a hotmail email I created. I tried the hotmail password and that did not work either????????????
