Win7 administrator problem

ok I.m using an admin account. recently I had a driver problem and needed to delete them out of the sytems directory so I.d get the new hardware detected again etc.... but could.nt just kept telling me i needed to have administrator rights even after popping into computer management and local user and groups and adding "sytem" to my account membership properties still no joy. now am i missing something??

 

You remove drivers using hardware management, not by deleting them from the system folder.

 

theres loads of differant softwares out there to allow you to take complete ownership of any directorys in your computer, one i have is just as simple as right click, and a take ownership button is there, command prompt pops up going through all the files giving you ownership of everything in that directory, works even on your system32 folder wich gives you shit even if you do have full priviledges, just google about
