I found some instructions to create a shortcut that will clear your clipboard when you double-click on it. You can follow the instructions below to create your own shortcut: Clear Clipboard Shortcut
Right-click on the desktop or elsewhere, and choose New==>Shortcut from the menu.
Then in the shortcut location box, enter the following command:
cmd /c “echo off | clip”
Make it even better by tweaking the icon: If you click the Change Icon button and then browse down to this file, you can find a clipboard icon:
%SystemRoot%\system32\shell32.dll
