Sun's SPARC servers all ran RISC chipsets and Sun's Solaris operating systems ran on RISC-architecture chipsets exclusively. And AFAIK there was never a M$ server OS that would run on SPARC hardware. There were a few flavors of Linux that would run on SPARC servers but for the better part, if you were a *NIX nutter and bought a SPARCStation for your personal entertainment, you were going to have to run Solaris on it.

Intergraph announced that they would port Windows NT to SPARCv9. That was in 1993, but nothing came out of it. There was a NeXTSTEP for SPARC along with several *BSD flavors.
