Some windows update will do that to you, don't recall which one.
I currently have the same problem...just haven't bothered trying to re-activate it.
if you don't do anything and install a bypass hack you will not be able to use your computer and will have to do a complete wipe of your hardrive.. so i sugguest you find one that works ..... seriously..
for those of you confused there will usually be an innate countdown timer within the system that counts down days when it hits a certain number it tells you how much you have left, when it reaches 0 you will not be able to boot up past windows start up,
the bypass deletes the file that asks for windows to be genuine w/o making the program (windows) recognize that its gone essentially
its all stuff that happens within the registry
