Yesterday, I rebooted from Linux to small Windows partition I keep on my notebook specially for rare occasion I try to run some Windows game. Sometimes I meet for LAN party of Age of Empires with a friend. Otherwise, I am not forced to interact with Windows very often, only sometimes, on a managed corporate desktop. Being internet service provider, I used to have to setup Windows networking for users, but these days, I usually setup only Wi-Fi routers and don't touch PCs.
There was not enough disk space on my historical partition, because for some reason, it reports 37 GB used even if entire Windows directory reports cca 20 GB and there is absolutely nothing installed (except Firefox and some weird local XML form filler required by early "digital government" attempt of Czech telco office).
I was amused how weird "Windows administration" feels this day. It is much worse, than even the early days of Linux. Not so much clicking in old style, but you paste really weird command lines into your admin PowerShell terminal, and you receive arcane numerical errors without explanation, so you must ask AI chatbot what it means!
We did not figured out, how to free the hidden 17 GB of my NFTS partition (14 GB were required), we released only about 1 GB and figured out, that up to 4 GB are used by some weird "hibernation file" (after installing Total commander). As I expected, rebooting everything always helped, but not enough,
But most funny fact, after not using Windows on daily bases for at least 20 years and not using it at all for 10 years is, that being administrator of supposedly "user friendly" desktop operating system is now more complicated, than being administrator of supposedly complex server operating system. I have more or less the same feedback from my dad, who for some reason insists on using Windows, even if the only app he really uses is the web browser.
It is not even pretending to be user friendly any more. People are stuck with complexity out of control.
