The clipboard on a computer is not a specific software that can be accessed; it is a tool used by the computer to save cut or copied information for pasting to another location. Accessing the clipboard on computers that use Windows Vista, 7 or 8, requires third-party software.
Older Windows operating systems (2000 and XP) have a clipboard viewer. The file is named "clipbrd.exe" and is located in the System32 folder, which is located in the Winnt or Windows folder. Another way to access the file is by using the Start menu, choosing Run, typing in "clipbrd" and pressing "Enter."
