My next OS will be some kind of Linux. I just had to reinstall Windows 11 because it corrupted it's install after some time. I had to uninstall so much crap and regedit so many thinks just to get it back to where I was before. I don't want Bing search in my windows search results. I don't want your stupid widgets and I don't want your browser or 90% of your default apps. And no I don't want office 360 or onedrive. So stop forcing it into my face.
When Linux gets Plasma 6 and HDR support there is only holding me back my Nvidia GPUs Linux compatibility.
While I hah to install windows 11 again I played a lot of games on my Steam Deck! It's is awesome and only some games with obscure anti cheat don't run. (well some times they don't run on windows too)
Just saying, but tweaking stuff via regedit is a surefire way to get your Windows install corrupted sooner or later.
dism, sfc... and disabling the preview update channel, are your friends to have a stable Windows install.
If you don't want Bing results in your search, then use something like Everything to search for files. It's faster, and will only show you files, all of them.
The widgets you can disable, and with Powertoys even bypass the start menu completely.
