From what I am able to tell it looks like the run time is there in the OS just disabled, may be like it is in the normal x86/x64 builds where its disabled.
BTW, when everyone was running Vista I hated Vista and ran 2008 as a workstation, ran as good as 7 does. 7 was a good OS so instead of running Server 2008 R2 I just used 7.
All this to use the Steam overlay.
