So I downloaded this Windows 7 SP1 RTM EXE, let me start from the begining, 1. I moded my BIOS with SLIC 2.1 for HP/COMPAQ 2. I installed windows 7 ultimate 3. I ran windows update & updated all the essensial update's 4. Then I used Windows Loader by DAZ to activate windows 7 now can I install Windows 7 SP1 RTM EXE or windows update did that already ?
