The much-anticipated successor to Windows Vista will be available as a download from Microsft's official site on Friday and is not just for tech-heads to use. In fact, Ballmer enthused: "I encourage you all to download it!"
But if you are a MSDN or TechNet subscriber, you can download the beta immediately.
Home Group networking
A short demo of Windows 7 showed some of the things that you will see in the beta, including easier access to multiple windows on the OS.
Side by side window boxes are also a cinch in Windows 7 – a quick click will snap to documents side by side, with no messy lining up.
There's also a new feature called 'jump lists', where you can quickly get to favourite music tracks and the like.
Networking computers shouldn't be a problem either, with a new option called Home Group, which will network your numerous PCs, Xbox 360s and any other Windows-related products in just a few clicks.
If you are lucky enough to own a touchscreen PC, then Windows 7 is touch-enabled, so your fingers can get right down to it with the Windows 7 beta.
The actual full version of Windows 7 should be hitting shelves everywhere January 2010.
Ballmer commented in his keynote about Windows 7's R&D, saying: "We are on track to deliver the best version of Windows ever, and working hard to get it right and to get it ready."
