The really useful PowerToys for Windows that were available for Windows XP have not yet moved over to Vista. A couple of them are Vista compatible but most are not. The one I wanted to install on Vista was the "Open Command Window Here" utility, which is really useful - just right-click on a folder in Windows Explorer, select it and a command window opens up.
The good news is that I found some (only a few) PowerToys for Windows Vista on the TechNet website and one of them is ... the "Open Command Window Here" utility! So for all you nerdy types like me who still use the command line and have upgraded to Vista, fear no more! Help and succor have arrived. The cavalry is here. You are saved. Halilooya, praise the lord, etc., etc., etc.
