We’ve heard plenty about the oft-rumored Windows 8.1. Most recently, we reported on the rumor that the Start Menu might finally be making a comeback. But it looks like Microsoft won’t just be updating its flagship OS this year.

Code in a recently leaked build has revealed that the company is prepping updates for Windows RT and Windows Server as well. The code references them as Windows RT 8.1 and Windows Server 2012 R2, possibly revealing the final names of these updates.

Windows RT 8.1 in particular is mentioned as a Preview version, so a public preview release shouldn’t be too far away from now. The Verge notes that Microsoft is expected to unveil all the different changes to Windows 8.1 in detail during its upcoming Build developer conference. Now it seems that they’ll most likely announce the updated versions of Windows RT and Windows Server during the same event as well.

The Microsoft Build Developer Conference is set to take place on June 26-28 of this year. Expect a flurry of news on Windows updates when it happens!
