How do I edit environment variables with new UI, for example? It's pretty common task and I always have to use that old UI. Thankfully it was actually slightly improved in Windows 10. Another thing is hotkeys to switch keyboard layout, it's still the same UI from Windows 98.

I'd recommend Eveditor (http://eveditor.com). Of course it would be better if Windows had something like that built-in.

The existing editor does everything you need. The only benefit for that tool would be editing %PATH% more easily, but Windows 10 includes a pretty good editor for that.

Win-key "edit" brings "Edit the system environment variables" up as first option.

That command launches old settings UI.

    rundll32 sysdm.cpl,EditEnvironmentVariables

is the most natural choice /s
