Neat Surf

NeatSurf is a powerful and easy to use IE privacy security utility. It prevents IE from writing to your history, cache, cookies, user data, etc. Just download and run NeatSurf.exe. It will start an instance of Internet Explorer and continue to run until another IE browser is opened regularly.

Free Snap

FreeSnap allows you to instantly resize any window edge to the corresponding screen edge. To make that window touch the right edge of the screen, for example, press and hold the left “Windows Key” and press the right arrow. It's just that simple. The number-pad keys work as well, regardless of the NumLock state.
