# Windows 8.1 Build 9374 contains interesting references to Windows RT 8.1 and Windows Server 2012 R2

Deep within Windows 8.1 build 9374, some interesting versioning has been spotted.

Of particular interest is the reference to Windows RT 8.1 Preview. How Windows RT will be updated this year is still not very clear at all.

Also of interest is the reference to Windows Server 2012 R2 which is new as well.

Lots of interesting stuff coming this summer…
