Hey,
I bought a hp laptop today and there was windows 8.1 already installed.. I need to put in the activation key.. so i called up the microsoft technical support.. the support guy ask me the install id and helped me out with the activation key which i put in the system and activated it. but i forgot to take a print shot or write down that activation key he gave me .. so if, for future reference i need that activation key then where should i find it..? I want to document the key and save it. Can you help please
