Microsoft has ported Windows and Office to ARM for a decade, and they have both x86-to-arm (Windows 10) and x64-to-arm (Windows 11) translation technologies. They also have ARM-based Surface devices in the Microsoft Store (looks like the Surface Pro X is the current model).

That said, the big business is still big business: Azure (Cloud), Office, and device management (MDM) / active directory are big focuses even in a heterogeneous computing environment that includes Chromebooks and Macs.
