so i recently bought windows 7 home premium and was originally planning on using it and the hdd its installed on in an upcoming build. but today i found out about the 16gb RAM limit of home premium and was wondering my options. the upcoming build will have 32gb ram in it. i bought a system builders license. is there a way to use that system builders license on another hdd and reinstall with windows 7 professional? or is the system builders license drm'ed at 1 all together. or to put it another way can i install with the same key twice of only one is active?
