There are alternate histories regarding that: like how non x86 versions of NT were subpar and had a dearth of available software, and likely only existed to freeze the market for open-systems unix vendors, all of which had those CPU architectures as a strategic advantage.

I played with NT on Alpha. It was a blazing-fast workstation that had almost no software except Softimage.

Lack of Office killed the desktop Windows on RISC.

On PPC, I remember SQL Server had some weird network bugs too.
