There is no way to find a lost network key. Can you log in to the router using a wired connection through your LAN port instead? Then you can change the network key to a new one which you can WRITE DOWN on a nice sticky label and paste to the router. (along with the admin password for the router)

Here is a code:
CD87T- HFP4C- V7X7H- 8VY68- W7D7M

If you have proof of purchase then contact Microsoft and explain the problem to them and they will issue you with a new product key.

pls factory reset ur notebook like this and u will never need a product key ,

Acer: When you first turn on the laptop and see the Acer logo screen, hold the ALT key and press the F10 key (you need to do this before the Acer logo disappears).

bcoz the OS comes pre-activated when it comes from factory if u still have problem then u should contact acer support at www.acer.com

pls rate me fixya if i have fixed ur problem
