Lately I’ve had a few TFS users complain to me that the TFS client (aka Team Explorer+Visual Studio) lacks the explorer integration you get with TortoiseSVN. Now, I’ve never felt the need for this feature but decided to do some research. And guess what? You CAN get explorer integration with TFS! In several different ways! 
I have not tried any of them (yet) but I’d recommend the power tools… mainly because it is Microsoft and they’ll eventually steamroll the competition (except maybe SvnBridge). Just pay attention to this small but important part of the “instructions” on the download page:
“Please note that the TFS Windows Shell Extensions are not installed by default. Choose Custom when prompted at installation to add the tool to the installed components.”
If I’m not too busy I’ll write up a short review of the TFS Windows Shell Extension in Visual Studio Team System 2008 Team Foundation Server Power Tools. Jeez… Microsoft, you relly need a shorter name for these tools!
