Hey Mausolos, I have really good experience with a freeware program for windows called "Take Ownership".
A google search of Take Ownership Windows 7 will bring up howtogeek.com with a link.
It avoids all need to turn off UAC and allows a simple right click to take ownership of files that windows says you can't edit. (for instance, If you install Rome into program files (x86), then install a mod into it, and it doesn't work due to UAC, just right click your rome folder and take ownership, and then all files will be editable, a reinstallation will not be necessary, UAC be damned)
User Access Control is a pain when modding anything on windows 7, but I've been using this program for years so I haven't dealt with it for awhile thankfully.
Hope that helps!
