Window Activation

[Guest]

I bought a new PC 3 weeks ago and it worked fine until today. When i turn my
PC on it says i need to activate my window and ask me yo type in the product
key which comes with the PC when i bought it. But when i type it in nothing
happened. I'm just wondering why doesn't my product key work.

you may need to call the company that you purchased the computer from.

what do you mean "nothing happened"?

you may need to click something after entering the key.
