Thus, every version of Windows NT has been released on at least one non-x86 platform.
- NT 3.1-3.5: x86, Alpha, MIPS
- NT 4.0: x86, Alpha, MIPS, PowerPC
- 2000 through 2008 R2 (7.0): x86, Itanium
- 2012 (8.0): x86, ARM
Notice that I listed Windows Server 2008 R2 as 7.0 rather than as 6.1. And that I listed Windows 2000 as 2000, rather than as 5.0.
In other words, I was giving the equivalent workstation OS -- not the internal NT version number.
