I'm glad to see a well-written, reasoned version of this type of post, and I want to add my two cents:
1. I've used Windows and Linux for literally 2 decades, at work and home. My recently built AMD machine has no issue with Windows 11, it functions well - largely as a 'Steam Launcher'.
2. Windows 11 really is worse. I've been upgraded to the Windows Server version as well as at home, and it's definitely a backwards step in terms of getting to work and having things at your fingertips. A
fresh install can't even open the Start Menu responsively. It was better a decade ago.
3. This is a trend that will get worse - Windows admins at Microsoft itself clearly use the command line and Azure cloud apps and it shows. None of the mainline admin tools, configuration boxes are being updated.
4. The recent security tsunami is something they're clearly drowning in. Everything is additions bolted onto additions in response to crises. I routinely hit multiple security confirmations, inside a corporate network, during day to day business, not my admin work. So, what is the value of Windows here, if it can't talk to itself?
5. People point to the flexibility of the AD group policies, but it's growth is unsustainable imo. All of our major issues seem to be AD issues, even running on Azure's latest.
Again, I use Win11 at home with few issues. But I don't think it's good at anything, I think it's just the lingua franca of game devs and that's it. They need a Windows NT type reset and I don't think they're up for it.
