Can't make my mind what to install. Windows 7 Ultimate and put SLIC 2.1 in my bios or use Enterprise method? The question is which one has less services running regarding the activation and genuinity. Is Ultimate constantly checking the bios and the license? Is the Enterprise better in that way? The computer will be used for DAW and I don't want any services messing the recording. Also It will be connected all the time to internet. In short which one is better if I want to be sure that my computer is working for me and not for Microsoft to check their genuinity all the time?
