Have you ever used any of the Sysinternals programs?  Programs like:

• ProcessExplorer - The UBER process examination tool.  It will tell you everything there is to know about every process running on your computer (dependencies, etc...).   Trust me, you will like it.
• FileMon - This one has saved my bacon many a time.  What is that darn file permission that is giving you an error 50 miles deep in the stack?  In the COM days it was much worse, but you still run into these issues when you have a fairly restricted security environment.
• ZoomIt - I use this all the time in my presentations.  It allows you to zoom in deep on a particular area of your screen, and draw things using a marker on that screen.  It is a great utility to do screencasts as well.
• AutoRuns - Examines your startup, and lets you know about those pesky winsock modifications (if you have ever had one, you know what I'm talking about) that leads to some nasty viral infections.

Well, to date, we have offered these via technet (http://technet.microsoft.com/sysinternals), which has been great.  Now we are offering these tools on an internet based "File Share", so that you can run them directly inside of a browser, or even a command prompt.  If you don't believe me, open cmd.exe and type in:  \\live.sysinternals.com\tools\procexp.exe

Now it becomes really easy to find those tools when you need them to debug your environments.  Enjoy!
