Of course you kids can nuke this - - since a proper crack will be released immediately after Windows 7 SP1 hits RTM. Until then your options are

1) Try activate with YMFM8-J2RV2-66G78-XPQ7C-4RY3B or some other key that leaxxx
2) slmgr -rearm when running cmd.exe as admin. This gives you 120 days time, by then a crack is out. For sure.
3) Best option - go steal a cdkey from any mega nerd you know.
