And guess what... We're using the same tools available to third party app developers, in an effort to ensure the dev platform is rock solid. The Start menu is just a universal XAML app. We don't have to do any special optimization on top of what the framework offers.

You guys have knocked it out of the park with the start menu. It's wonderful. Besides occasionally having to kill explorer because it becomes non-responsive it's been an absolute pleasure to use. I really like that you guys have downgraded the size a bit since earlier builds; really sleek and useful now.
What's happening with search? Is using Cortana mandatory? What's up with always using web search? Why can't I turn this web search off? Do I absolutely must block off bing and all Microsoft services at the network level to stop this?
Well it does help that you can just email the perf people in devdiv and have the single largest concentration of low level windows performance experts available for free
The start menu is great code but mom and pop dev shop doesn't have hundreds of top devs available :)
