It's not your average office I'll admit that, but we do have non-technical people on Linux that work help desk and RMA (think $100k networking gear).
Windows Rant Incoming:
Windows Update sucks. It just sucks. I fucking hate it. It fails for no reason, it fails for every reason. With how important updates are for Windows updating should JUST WORK.
I was trying to curate updates via WSUS and then moved to W4B SAC but recently said eff it and just let them update however they want. Just let the updates fail, they'll work eventually. I really don't care anymore or have the energy to.
