Windows 10: Why did windows suddenly de-activate?

writing this up at 19:22 and stressed out of my mind. yesterday windows was activated, no "activate windows" message. and today after i installed an update it suddenly de-activates or something. and it took me a while to notice, but now i'm worried. what do i do to fix this stuff? i don't really know how much this will affect windows but i just want to re-activate my windows just incase something important was affected

My PC suddenly says its not activated

So now I have a clean install and windows is activated, what are my steps to find out why my original windows install wasn’t activated......

I await instructions........

and apart from checking activation, I do everything else as per your suggestions......will in future check validated once a month.......

 

My PC suddenly says its not activated

For verification, now you are saying it isn't activated and Microsoft won't help you?

 

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. Reboot and it still does it. This happens to be on my main machine, running windows 7.

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?
