I've moved onto the Windows Experience team. It should a lot of fun to continue to follow Guided Help, and some of my other projects but my emphasis now is on the Windows Experience - things like explorer and the like. I'm also the new owner of the LUA/UAC shell UI, which should be interesting.
This will probably change the kinds of things that I blog about - you can expect more shell-related topics, as well as various user experience discussions.
We have a lot of changes that we're excited about, and I look forward to building on Windows Vista.
