Shapeshifter

Shapeshifter is the best clipboard manager out there, and the most maintained one as well. It has been awarded more than 100 5-star awards from different download sites worldwide and has been featured on national TV in Brazil and magazines in Russia.

What makes Shapeshifter special is that you don't change your current habits while using it. Pressing CTRL + V normally pastes the last inserted item from the clipboard, but holding down CTRL + V instead displays a beautiful interface allowing you to easily look through your clipboard history, and select the item you need.

There is no limit on the types of data Shapeshifter supports. Even customized data between applications! Distinguishing between clipboard formats in the history is also easy, since every data-type has its own visual representation in the user interface.

The program itself comes with adjustable settings, and the user interface adapts to your Windows Aero color from your personal customizations.

There is nothing that can compete.
