That may be a bad idea. I believe that there are consistency check in Windows 7 that may cause unfortunate things to happen if you play with the system clock.
Did you run slmgr -rearm from a command window with elevated privileges? It's necessary. (To open a command line window with elevated privileges, go to the system 32 directory in your Windows directory. Run cmd.exe as administrator.)
I'm not sure whether this will work with an expired grace period. One suggestion I've seen is that you can boot into Safe Mode and run it then. Haven't tried it.
