Found quite a gem today.  I've always installed the Windows Powertoys feature to get the "Open Command Window here" option when you right-click a folder in Explorer.  I've discovered that this is not needed in Vista.

How does that saying go..."Real men use DOS, right?"  I can never seem to get completely away from needing a Command Shell for batch file testing, etc.  The problem is trying to navigate quickly in a DOS box to a deeply nested directory.  For Vista, there's a similar product called TweakVI as seen here:

It's got most of the features of the old Powertoys TweakUI, but I still didn't get the right-click Command Window feature.  A quick search today turned up this:

That's right, Vista already had it and I didn't even know it!  Just hold the shift key as you right-click and you automatically see the option.
