Hopefully you
registered to acquire a Second Shot voucher! I was going to post earlier but didn't want to jinx myself. I just got back with an 800. Not as good as I wanted, but I passed! Some of those questions are evil. They give us the
Skills Being Measured and you've seen the exam in person so there shouldn't be any surprises now. They cover
everything on
the list! Research everything that you don't know and review everything that you think you already know.
Experiment! I've been doing some of the stuff so long that it seems like common sense. I enjoy experimenting and hands on always works for me. I switched from XP to 7 RC at home last June. I switched to 7 Ultimate in July thanks to Technet!
TNWIN7L knocks the price down to $250 and we get all of M$'s software with lots of keys! I migrated to Vista Enterprise at work around the same time and have been supporting customers on it since. We have a great Public key infrastructure, I administer VPN accounts and client software, and I deal with encryption from hell on a daily basis so that stuff was fairly easy. I had to spend a lot of time
Building a Standard Image of Windows, going over the
Automated Installation of Windows 7 Overview, and learning about the
Deployment Image Servicing and Management (DISM) Tool. I had to memorize M$'s official hardware requirements, upgrade limitations from Vista, and other BS like that too.
Technical Guidance can be found
here (very important link). You want VPN? Click "What’s New in Networking". Take note of the "special considerations" and don't forget about
the list "establishing VPN connections and authentication; enabling a VPN reconnect;" Scroll down a little and you'll see "What's New in User Account Control." Jump back to
the list and see "configuring local security policy; configuring admin vs. standard UAC prompt behaviors; configuring Secure Desktop:" Time to track those down and start clicking on stuff or asking questions.

Hope it helps!
