Microsoft Offers Windows 8 Free Trial

Microsoft gave reviewers and the public their first taste of its revolutionary new operating system Windows 8. The free trial was offered on Feb. 29.

Windows 8 will run on tablets as well as desktops and laptops — and is a sea-change for Windows that is seen as a make-or-break opportunity for Microsoft.

Windows 8 will come in two variations — one that works on desktops and laptops, and a new version for the ARM microprocessors in tablets, smartphones and other portable devices.

There is no set release date, but it's widely expected to be available in autumn — offering Microsoft Office free on tablets, which could be a "killer app" that puts Windows 8 machines ahead of Apple devices.
