Microsoft Windows will be just fine for a very long time. Corporate security systems and IT admin doesn't typically run on Linux well or at all, but it does run on Windows and MacOS. We're using popular auth software at my work, but it does not run on Linux otherwise I'd have switched to Linux on my work machines a while ago. That alone is 3 computers that won't ever have Linux. Anecdotal, I know, but the corporate world does not care about Linux as a computing platform outside of servers and machines that people don't use as a desktop/laptop to get work done. Sadly, Microsoft isn't going anywhere and I doubt they are worried about losing any market share to Linux.
