I puzzles me to no end why the typical office clerk should care about the OS at all. I understand that secretaries will be trained on MS Word and will then have a strong preference to use such (or at least something which very closely resembles it). Same for accountants with Excel. But clerks in e.g. Revenue Service? Those I expect to interact (perhaps these days via a Web interface) with custom software. Why would those ever see a 'Start' button or somesuch?
That hasn't been my experience working in Corporate America at all. Everyone gets a company laptop and they use it for whatever they want. Whether that's Excel, Google Sheets, or Netflix at home.
People think company hardware is their personal hardware and they have preferences.
I had a company phone once (terrible experience) and I'd routinely get txts from random services and people outside our company thinking it was the previous owner. The last employee who had used it mixed company use and personal use.
