In Windows, the clipboard is used to temporarily store things such as files, pictures and documents as they are copied and pasted. Over time the clipboard gets cluttered and will eventually start to slow down the operating system. It is necessary that the clip board be cleared periodically to free up memory space and prevent system issues. When you clear the clipboard you should instantly see an improvement in the computer's performance.
