Windows 7 Ultimate 64-bit

The new generation of Microsoft's Windows 7 Ultimate operating system brings a host of new features while optimizing existing ones.

Working on your computer will become faster, easier and more fun. Of course, it also includes full support for multi-core processors and DirectX 11 compliant graphics cards.

Windows 7 has lower hardware requirements than previous Windows Vista versions, making it suitable for less powerful laptops and netbooks.

New features include a redesigned taskbar that helps you easily handle multiple tasks at once. Working with windows is much more intuitive; simply dragging to one of the edges can maximize windows or display them halfway across the screen. You'll appreciate the improved Windows Media Center when playing multimedia.

Of course, the popular Quick Search in the Start bar has been retained and now provides even better results.

The Home Group feature takes the fear out of sharing files and printers on your home network. Connect two or more Windows 7 computers and Home Group makes it easy to automatically start sharing music, pictures, videos and library documents with other members of your household.

The Ultimate version is suitable for demanding users. It includes all the features of both Home Premium and Professional versions, plus adds the ability to switch between 35 languages and encrypt disk contents with BitLocker.
