You will have to change some day.. 7264 is a beta and rtm is full final release which is better. Impossible ? maybe, have you tried reading thread ? Not sure wether it says if its possible to activate it.
Only maybe 8 builds is difference with RTM and 7264. All of activators of this thread replacing files from RC build, so 7264 is activated to 2nd March 2010.
Yeah, but June 1st is when build 7264 and other pre-release builds nuke themselves, and then you will have no choice but to do a fresh install of the RTM version. Unless you're prepared to put up with pop-ups and a black screen and the PC rebooting every 2 hours, then go right ahead!
You're kidding right ? - none of the activators work for the pre-RTM stuff they only EVER faked it by making Frankenbuild versions which M$ spots so easily - they nuked that sort of crap with Vista SP1 - nobody fixed the time bomb and why would anybody bother expending the energy fixing that when the RTM version doesn't have it ??? Oh, hang on a minute - you could format your drive - set your date to whatever date before the 2 hour shutdown started - re-install 7264 and keep resetting your date - Oh - and disconnect from the net so it never discovers the true date. At least you could play solitare. You're kidding right ?
