Windows 7 Professional from Microsoft is the long-awaited successor to the ubiquitous Windows Vista operating system. Building upon Vista's impressive feature set, Windows 7 adds many features which simplify the way you use your PC, as well as the way that your PC connects to the world.
The Professional edition of Windows 7 is designed to meet the needs of business and home use alike. It omits none of the features that are found in the Home Premium edition of the software. These include improved desktop navigation, improved speed, the Internet Explorer 8 web browser, Windows Media Center, and HomeGroup networking.
Features gained by moving up to the Professional edition include Windows XP Mode, which allows you to run legacy applications in a true virtualization of Windows XP. You'll also be able to join Domains, which is often a requirement for connecting to corporate networks. Finally, the Professional edition adds the ability to backup your system to a home or business network.
This upgrade requires Windows 7 Home Premium to already be installed on the computer. Both the 32-bit and 64-bit editions of the operating system are available via download, allowing you to install the edition which best suits your needs.
This product comes with a license key. No CD is included.
