Guidgen Console 2.0.0.6

Guidgen console is a command line application that generates X number of guids in the format you want - pasting them to the clipboard - if you wish. But that's not all! It also allows pipe usage to find and replace GUIDs or just run in the background as a reformatter.
Supports zero guids, sequential guids, and plain vanilla guids.
