Windows 7 is officially released to the public on Thursday. CNET provides information on just what you're getting with your Windows 7 Starter, Home Premium, Professional, or Ultimate, take a look at the chart and explanation below.
Although it sounds full-featured, Home Premium definitely offers less than Windows 7 Pro or Windows 7 Ultimate. Location-aware printing, presentation mode, and XP Mode are not available. Neither is BitLocker, AppLocker, the remote desktop host feature, nor Aero glass via remote. AppLocker is the new feature that allows system administrators to restrict program access from the Group Policy settings. You also can't use the Windows 7 Backup and Restore feature to work with network drives, just like Windows 7 Starter. That feature doesn't come in until the Pro version.
Windosw 7 Professional is the power user edition of the new operating system, retailing for $199.99. In addition to all the features in the Home Premium edition, Pro is designed to be flexible for dual use in the home and small business. It will support up to 192GB of physical RAM in 64-bit mode, it supports legacy Windows XP productivity programs via XP Mode, it can work with two physical processors, and it can back up your data to a networked drive. It still lacks the AppLocker and BitLocker features, it can't handle the pretty but superfluous remote Aero glass support, and it lacks the multilingual interface support pack.
Windows 7 Ultimate, retailing for $219.99, supports those features plus virtual hard-disk booting and a subsystem for Unix applications. Although it's possible to conceive of some home uses for Ultimate, the features that separate it from Windows 7 Pro set it in a class that's almost exclusively for intensive international or network use. For most office or home power users, it's not really recommended.
