The room was packed to capacity, ok beyond capacity, for the first day of the hands-on lab. As far as I can see all of the scheduling and technical stuff is going very smoothly. It's really exciting to see this many people dedicating this much time to the WDK. The best story I've heard all day was instances of people bringing prefast for drivers errors in and asking our devs for help determining what the problem was. This opportunity for TAP partners to work directly with the devs and testers who created these tools is unlike anything I've ever seen. It is truely a great opportunity. I'm also impressed by the number of countries represented. I'm aware of at least the US, Canada, the UK, Taiwan, Korea and Japan.
