> I can live with Windows 11 being a little slow
Why accept mediocrity when Microsoft has shown to be capable of producing something better than their current iteration of Windows? Whether you prefer Windows 2000 or XP or 7 or one of the server versions over 10/11, all of those were in many ways 'better' than 11.
> I can deal with File Explorer issues
Again, why? It is not as if those issues are the result of Microsoft adding something useable or worthwhile, they're just the result of MS adding even more ballast to an already overburdened system.
> I can write my own tools to manage some of that
Yes, you can, and...
> PowerShell is simple enough for many tasks
...so you're getting to experience the power of the shell like *nix-users have been espousing for more than half a century now. Welcome to the club and welcome to the CLI. Here we use words to communicate instead of pictures, we outgrew those once we left play school.
If you want to use Windows just use one of the previous versions as long as you can while preparing to move over to the greener Wine-yards in Linux-land. Unless there is a big shake-up within Microsoft - unlikely - it looks like Windows as an operating system is a dead-end street. It will be turned into a straight jacket where you will comply with whatever the current business plan dictates. Escape while you still can I'd say, there are many alternatives on offer.
