Yep, IT worker here and all of our client machines run Windows 11 with all the usual Office 365 stuff. Most of our servers run Windows too. A small amount of servers are Linux-based, usually VMware hosts and some virtual appliances. Broadcom is fucking us over a barrel on VMware licensing/support but the inertia is so strong that the powers that be won't even entertain migrating to something like Proxmox. Something something Gartner top quadrant...
Work provides us relatively decent Dell Latitude hardware but we are stuck using the corporate Windows 11 image.
If they'd let us bring our own tech I'd be on a Thinkpad running Fedora and just use remote desktop to access all of the Microsoft shit.
