Microsoft on Tuesday said participants of the company’s Windows Insider Program will get an early look at Windows 10 starting tomorrow. Mind you, the version made available will simply be a Technical Preview for laptops and desktops, though it should give avid fans the opportunity to get a quick taste of Microsoft’s next big Windows initiative.

Launching “later in the year” in 2015, Windows 10 is Microsoft’s biggest ever update, and is designed to run on the “broadest types of devices ever,” the company said. That suggests it will finally attempt to create unity between the desktop, laptop, tablet and mobile experiences. There are some other major improvements coming, of course, such as the return of the beloved Start menu, which has been sorely missed by Windows fans.

This update has been a long time coming, and although the full version won’t launch to the public for some time, you can start familiarizing yourself with some of the features with the Technical Preview starting tomorrow.
