Recently I did a clean install from the windows installation tool off a CD I made. Soon after logging on and making my first account (again!) I couldn't open the C drive. I messed with the owner options and made my account the owner so I could open it. Possibly before or maybe after (I'm not sure) I realised I wasn't able to use any admin settings, (like add another account or see advanced system settings) open any applications that required admin rights (like CMD or any installation file) or do anything in the system menu. I've tried to look up the solution but can't find anything that fits the description of my problem. Any help is welcome. Thanks in advance for at least reading this.
