Whether you use Windows or Linux, the Windows key is the foundation of many useful keyboard shortcuts. You know, hold it down plus some other key.
Whatever your preferred OS, look them up! You may find a few you would like to start using.
But yeah, on my work computer which is a Windows machine, I often use it to open the start menu and start typing the name of the app I want to launch. It’s faster than clicking on an icon somewhere if your hands are already on the keyboard.
Yeah, I do all my development in WSL2 (Ubuntu) at work every day. I use VSCode on the Windows 11 host. It’s great!
Would I prefer to use Linux natively? Sure, but I also have to support some Windows-only legacy code and a D365 environment or two, so Windows makes sense.
