Hi all. I'm trying to lock a folder in windows 7 in a way to asks for username and password everytime you access it. I tried using permissions and left only SYSTEM and ADMINISTRATORS group but as soon as I access the folder I got a prompt to continue the operation and it allowed me without entering username/pass. My account is admin on windows but I want it locked for everyone, including me. How can I do this with windows without 3rd party programs? Thank you.
