Run this on the command line:
taskkill /F /IM chrome.exe /T
/F = force kill /IM = image name /T = kill all child processes as well
To create a shortcut, right-click the desktop, then New -> Shortcut.
For location, type the following:
taskkill.exe /F /IM chrome.exe /T
Then, give your shortcut a name like “Kill Chrome”, and you’re done.
