Yes it is OEM Key located back of my computer. It came with Windows 7 already installed, but i re installed Windows 7 because of a program not letting me go on internet and i also couldn't remove that program as it asked for a password, but i didn't know my password. I found the password just a moment ago when i looked at all the papers i had in my box where the computer came in. I didn't create a restore point, im not sure where to check for them as im new to Windows 7.
