According to The Verge, Microsoft fans will be getting a nice surprise tomorrow when the company releases the Release Preview of its upcoming Windows 8 operating system. What was first set to debut in early June, sources are indicating that Microsoft will officially release it tomorrow–a week early.

The Release Preview is Microsoft’s third official build for public consumption, following the Developer and Consumer previews respectively. This build is said to include hints at what the aero-less desktop will look like (though users won’t see the full UI changes until the final retail build) as well as built-in Adobe Flash in the Metro UI version of Internet Explorer. Although I can’t say I’m thrilled about the many changes in Windows 8, I’ll still be downloading the new Release Preview to give Microsoft another chance to make me like Windows 8 (hopefully they can). If you do download it, don’t forget about our Windows 8 Virtual Machine installation guide.

Will you be checking out the Release Preview?
