Windows 7 Professional has everything you need for work and home.

Simplify everyday tasks: find something instantly, compare documents side-by-side, or easily back-up your complete system over a network.
Enjoy a PC that works the way you want it to; supports 64-bit technologies and offers XP Mode for your business productivity applications.
Make new things possible: watch Internet TV, pause, rewind, and record TV or use Touch to interact with your PC in new ways.


  • Use XP Mode: Run many existing productivity and business programs designed for Windows XP – additional necessary software is available for download, free-of-charge from Microsoft.
  • Save time and money resolving IT issues: Take advantage of the powerful diagnostics and troubleshooters built into Action Center to resolve many computer problems on your own.
  • Interact with any compatible device connected to your computer: See device pictures and status and run common tasks from a single window.
  • Connect multiple PCs, with or without a server: Use Domain Join to connect PCs quickly and more securely to your wired or wireless domain network.
  • Automatically back up your files: Protect your data from user error, hardware failure, and other problems. You can back up your files to an external hard drive, secondary hard drive, writable CD or DVD, or to a network location.
  • Share files across the various PCs in your home: Use HomeGroup to connect your PCs running Windows 7 to a single printer. Specify exactly what you want to share from each PC with all the PCs in the HomeGroup.
  • Find virtually anything on your PC – from documents to photos to e-mail: Just click on the Start button, and enter a word or few letters in the name or file you want into the search box, and you’ll get an organised list of results.
  • Find the right printer: Use Location Aware Printing to identify your printer when moving between the office and home.

Windows 7 Upgrade Considerations

Depending on the version of Windows you're currently running, installing Windows 7 on your PC may be a lengthy process. Run Windows 7 Upgrade Advisor to make sure your PC can run Windows 7, and then review the information below prior to buying or installing Windows 7 on your PC.

If you switch from a 64-bit version to a 32-bit version of Windows, or vice versa, you'll need to do a custom (clean) installation. This may also impact other parts of your system.
