ExtractNow

This program allows the user to unzip any type of file without changing the default zipping functionality built into Windows.  To use it, you open the program then drag and drop your zip file into it and extract now does the rest.

It would be nice to be part of the package library because the installer typically includes junkware.

From their website: "ExtractNow is a simple utility that allows you to extract multiple archives quickly and easily. ExtractNow is not a complete archival solution. It's main purpose is to allow the user to extract multiple archives easily." http://www.extractnow.com/
