Features of Windows 7 Professional include remote desktop hosting, Windows XP mode, Windows Server domain joining and the ability to encrypt files and folders. All features of lesser editions of Windows 7, such as Home Basic and Home Premium, are also available in the Professional edition.
Remote desktop allows other computers to gain access to the host computer for, say, troubleshooting and performing tasks remotely. Windows XP mode allows users to run legacy applications from within Windows 7. Joining a Windows Server domain lets a computer become part of a large network and helps an IT administrator manage the computer as part of said network. To help users safeguard personal information, Windows 7 Professional offers encryption on a file-by-file basis.
Like the Home Premium edition, Windows 7 Professional comes with Internet Explorer 8 pre-installed, and allows users to create and join HomeGroup sessions and watch live television through Windows Media Center. While it is designed for computers in a corporate network environment, Windows 7 Professional lacks some business-oriented features found in the Ultimate edition. These include BitLocker drive encryption, DirectAccess file sharing, virtual hard disk booting and a multilingual user interface. Users who intend to switch to Windows 7 Professional or another edition can make use of Windows Anytime Upgrade.
