Windows 7 Professional is the latest Microsoft operating system. It features enhanced performance, a simplified interface, expanded search capabilities, and more secure networking. This 64-bit version operates on a computer with a 64-bit processor and 64-bit drivers.
This is an upgrade product. To install this operating system, you must have a licenced installation of one of the following operating systems on the device where you are installing the upgrade: Windows Vista Enterprise, Business, or Ultimate; Windows XP Professional or Tablet PC; Windows 2000 Professional; Windows NT Workstation 4.0; or Windows 98. You cannot upgrade from the Home editions of Windows XP or Windows Vista. Unless you are upgrading from Windows Vista, this installation requires a "clean install." This means that if the computer has an existing operating system, you must remove all operating system files and applications, install the system, and reinstall the applications.

Important Volume Licencing Information: With Windows 7, organisations can choose between two types of volume licence keys for product activation: a Key Management Service (KMS) licence key or a Multiple Activation Key (MAK).

A KMS key requires at least 25 computers on a network for activation. Organisations with fewer than 25 computers should request a MAK from the Volume Licencing website after receiving this product. For information about obtaining a MAK or deciding which type of key to use, see http://www.microsoft.com/germany/lizenzen/produktaktivierung/default.mspx about Microsoft Volume Licencing Keys.
