Hi, I have this problem on my pc and I've had it before on other machines running Win8 as well. It's when I'm working under my regular user account (no admin privileges) and when I need to browse some files in my admin user folder, I navigate there and after being prompted for my admin password I gain access to the directory. So far so good. But from then on, Windows always grants me access to the entire admin folder without asking for the password ever again. So even after I have logged out of my working user account, after having rebooted the machine or had it shut off, it just never prompts again and the admin directory stays accessible through the regular user account forever. Which sucks, imo it should not do that. I have no idea why this is designed in such a way (unsafe) and I don't know where to begin trying to fix it. I just want permission on a per-session basis when I incidentally need a file from the admin folder, so I prefer the privileges to expire after a single explorer session which had prompted for the password to begin with. The two accounts have different passwords. Also, UAC still always prompts for admin password when executing files As Administrator. My question, How can I make Windows not remember these credentials from browsing in the folders? Update: When I do 'net user admin' it says "Password required No", where for my regular user account it says Yes. Not sure if this means anything but it seems suspicious. When I go to log-on with admin account, Windows does require my password for it. Also, admin folder properties show obvious reason why I am granted access. (attachment) So I know how to remove the credentials from memory, but the problem is not fixed there because next time it will just remember them again. Also, my Users group shows some suspicious entries of which I doubt should even be there. See screenshot... If someone knows anything about this please let me know.
