With the latest windows update, I lost my internet connection (actually, the update itself failed no matter what I did). I desperately needed my internet connection working because I needed to send a work for college. So I reset the computer from Windows 10 menu (latest build)
Everything's working fine, but while I was changing a couple of settings, I find out that my Windows was not activated. I click on the "activate" button but nothing happens, and when I tell myself "okay, no biggie, let's type the key manually" I notice my Dell DOES NOT have a sticker on it's back with the product key! I do have an original Windows8 sticker (updated to W10 two months ago) but nothing about the product key, not on the laptop nor the box. And since it was a gift from a relative that visited the US I can't go to the store to ask about it.
I tried getting my product key with several third-party programs, but when I enter the key that I get, Windows jumps me with error 0xc0000022
Any help? I'm actually panicking since I don't have any proof that my Windows is legit aside from that shiny W8 sticker on the back...
EDIT: So I found out how to check my key product without using any third party software and there it is, apparently:
So I tried to put the key again, and now I have THIS error!
