How do I open my snipping tool on my new Windows 10 laptop?
There is a simple way to access things in Windows 10. You can call the Search function using Windows key + Q then simply type snipping tool. The result list will display the installed application. Select it with your keyboard or mouse and launch it. It's practically, the same Snipping Tool available in Windows 7, Windows 8, Windows 10.
