Teach you a key to close all running programs of Win7 system

After a busy day of work, when you are ready to turn off your computer, you will find that many running programs on the Windows 7 taskbar need to be closed one by one. Maybe you just want to be able to turn them off at once. More trouble. In fact, this idea can be done completely, and does not require any special software, you can do it yourself.
First, right click on your Windows 7 desktop, create a new shortcut, and enter the following:
taskkill /F /FI "USERNAME eq PChome" /FI "IMAGENAME ne explorer.exe" /FI "IMAGENAME ne dwm.exe"
Note, please replace “PChome” with your computer's personal username.
Then [Next] name this shortcut, for example: close all processes.
Click the [Finish] shortcut to create it, you can put it on the desktop, or lock it to the Windows 7 taskbar. Then just start a few programs and double-click on the shortcut to see if it's all closed. How about this small shortcut makes it easy to close the program.
