The same reason most organizations use it -- inertia and because it's been the standard for so long, it's the best at what it does.

The startup I used to work at was exclusively on OSX + GoogleDocs, when we were small, but as we grew (and especially when the Finance team grew) more and more employees found a need for the MS Office Suite as well as apps that only run on Windows, so they started rolling out Windows VM's and then full Windows machines.

I'm curious which apps only run on Windows. We are also a MacOS + Google Workspace shop and the microsoft requirements have been slowly seeping in.

I don't know what native apps they needed Windows for (I wasn't doing IT work by then), but I was still setting up PC's when they said they needed Windows Excel (not Excel on Mac, not Office365) for some forecasting spreadsheet product they purchased - it only ran on native Excel. We gave them Windows in a VM on their Mac at first, but eventually they had more and more apps that ran on Windows and moved from Mac to Windows laptops.
