but I'll be damned if I let Win 7 tell me what I can and can't do with my own computer. How can I override Win 7's bitch ass security settings?

lol
uh huh,,, till someone gets infected with crap and then bitches about how easy it is for windows to get infected.
What folder is set as read only that you are trying to change?
If you screw up your system,, that is on you,, don't come cryin about it when YOU brick it.
