Windows Vista editions to be easily upgradable

Every "edition" of Windows Vista will have all the features and functionality of the most expensive edition, but they'll just be locked away. Users will be able to get features of a more expensive edition by buying a key from Microsoft - you won't have to have buy a new CD/DVD package.

It isn't clear if all the bits of the complete Windows Vista will be installed on the harddrive or if you'll need the CD/DVD to install upgrades. If the former is true, buying from PC builders like Dell, who generally package basic editions of Windows, will be more attractive as the opportunity to get a more complete Windows will only be a click and credit card away. But having a few gigabtyes of data you're not using on you harddrive isn't too attractive.


Microsoft has not made an official statement, but sources close to the company say this type of distribution system is the plan. Things might change.

A source familiar with this upgrade plan says with the five editions of Windows XP, Microsoft manages five "master images." The company will only have to manage one master image of Vista with the new plan.

Microsoft has announced seven editions of Windows Vista. In order of price and functionality:

• Vista Starter Edition
• Vista Home Basic Edition
• Vista Home Premium Edition
• Vista Professional Edition
• Vista Small Business Edition
• Vista Enterprise Edition
• Vista Ultimate Edition
