You can copy, paste, & cut the content in and out from Windows clipboard but do you know if there is a way to clear it up? Apparently, there is.
When needed, simply run the following command in the Command Prompt window, or from Win+R Run window:
cmd /c “echo off | clip”
To simplify, you can create a shortcut with the command as the location of the item, and save it in a place where you can easily access, such as the desktop.
To find out if it works, check out these tips to view what’s in your clipboard.
