reset

Hello, Can someone help me with spoofing like HWID and all that. I watched Videos all that shit but dont get it. If i reset my computer will there be new HWID and all or do i need still to spoof?!

I forgot my password for the updater, so once I'm able to re purchase can I put a new password and be sent a new email? :D thank you im also getting a new pc soon, I'll need a HWID reset right?
