Though you can use the Task Manager to quit most processes, it's not always the most convenient or efficient way.

You can also use the Command Prompt to easily kill an unresponsive process.
In this tutorial, you will learn how to force quit softwares on windows using the command taskkill.
1) Open Command Prompt (run as administrator)
2) At the Command Prompt, type tasklist > Enter
3)Find the name of the software/process (first column). Note the PID number for that process in the second column. You will need this information in the next step.

taskkill /im 14956 (press enter)
taskkill /im SnippingTool.exe
Add the /F to the end of the command to force quit all processes for that software if you receive this error message: This process can only be terminated forcefully
