Shortcut to close metro apps from desktop

Solution 1:

Short answer! There is no shortcut to do it.

May be someone do it with autohotkey script when they will give a support to Modern UI apps.

Edit: According to your last lines for snap shortcut there is

Win+. for snap current Modern UI to right side

Win+Shift+. for snap current Modern UI to left side

Solution 2:

If you want to close all the Metro apps from the Desktop at once, you can see this question.

On Windows 8; all "modern" applications seem to be dependent on explorer.exe. Restarting the process from Task Manager seems to stop all Windows 8 (modern) applications.

So restarting the explorer.exe process should close all Metro apps immediately.

If you want to create a shortcut to restart explorer.exe from the Desktop, you can create a batch file with these commands:

taskkill /IM explorer.exe /F
START explorer.exe

Or if you want to only kill explorer.exe and start it manually later:

taskkill /IM explorer.exe /F
START taskmgr

and then:

1. File → Run new task.
2. Type explorer and hit Enter.

Solution 3:

Aside from the answer "it's not possible" other people already gave, I want to make sure that everybody understands that there is no need to close a Windows 8 app because they are automatically closed for you by the OS. Much like iOS and Android handle this.
