Been a while since I posted a download pick but here is one I just had to share. It is called DTaskManager. This utility is written by a guy named Dimitrios Coutsoumbas and really revs up TaskMan in Windows XP and Vista. Some cool features are that you can click on an application and choose the "Go to process" button and it will take you directly to the process that is associated with the app.
It also gives you the ability to see all active ports and find out what file is using that port. You can also temporarily suspend processes, or really kill a process. Lots of goodies with this one!
