Yes, you will need to buy an upgrade copy of Ultimate Edition to do so, or use Windows Anytime Upgrade available from the Microsoft website. Contact Microsoft if you need to know whether you can use upgrade in-place as you will be able to keep all of your files and folders this way.
Windows Vista Ultimate is a premium operating system produced by the Microsoft Corporation. The term "Ultimate" describes the product as the most premium version of Windows Vista, it includes all additional features. Another example of "Windows Vista Ultimate" : Windows Vista Home Basic
Probably premium or ultimate
THere is no such OS called windows premium., but in vista there are many flavours called vista basic, home premium and vista ultimate. In these variations the higher you go the more extra features u get and obviously the more you pay for it. LIke vista basic does have windows aero and home premium does not have dream scenes, bit locker etc which ultimate has., but the basic OS is the same. :)
Home Premium................... windows 7 home premiun, my opinion.
Home premium and Ultimate.
Vista Home Premium is produced by Microsoft Windows. It is one edition of the Vista series, the others are: starter; home basic; business; ultimate; and, enterprise.
