Windows Suddenly Deactivated without Reason

I got this PC around Christmas, and ever since, i've had windows pro. I myself did not activate it, since i did not actually build the PC, so i don't know who activated Windows. As of today, my windows has been deactivated, for no reason. Can i get it re-activated?

Thanks.

 

Windows Update suddenly hangs?

Windows Update is suddenly hanging for some reason... I went and downloaded and installed the first bunch of updates, restarted when asked, and now when I go back to windows update I just get the window with a white box forever.

I've also noticed when I reboot it says configuring windows update, step 3 of 3, 47%. Maybe it somehow skipped something and is screwed forever?
