It is a Vista Business Retail Edition which means it does not require a serial key and will be activated automatically within 3 days. You can't boot this DVD, It is to be cleanly installed from windows on a spare partition or the same whole drive. You can delete previous windows files later on. Vista is great but Business version lacks Media Center which I think can be installed later on. A working crack is included just in case.
