How can I completely 'exit' the game with 'Windows' button?

[Hyperian-auchindoun]

I do some multitasking while I play WOW, and need to quickly navigate between the apps.
When I click the ‚Windows‘ button, I’m still in the game and only taskbar opens, where I have to click the app manually because WoW is still playing in windows mode, and I need to click on the app to close it and exit WoW windows mode.
Is there an option to completely leave WoW when I hit the Win button without clicking app in order to close WoW?

Das ist das deutsche Forum, weshalb man hier deutsch schreiben soll.

Aber mal eine Idee zu deinem Problem. Kann es sein, dass du im Fullscreen-Fenster- Modus spielst? Ich bin nicht sicher, ob das wirklich eine Lösung bietet, aber hast du mal versucht WoW im echten Fenster-Modus zu spielen? Möglicherweise hilft das.

My english is bad, but also in english: do you play in „fullscreen-windows“-mode? Maybe you can try if your problem can be solved by playing in „windows“-mode only.
