|If you're trying to install Windows, there is supposed to be an official Microsoft label on the outside of your computer case that has a Product Key on it for the version of Windows orginally installed on the computer, which must be the same as the Windows version you're installing . E,g. OEM Vista Home Premium, or OEM Vitsa Home Premium 64 bit. |
You are NOT required to Register your Windows version installation with Microsoft, but you must Activate Wndows.
