Update Virtual PC before installing Windows 7

I installed Windows 7 as a Virtual PC last night and all went well, except that my mouse responded slowly. So with the operating system in place I attempted to install the Virtual Machine additions. I actually had to run the setup myself because the menu option did not start the process as it had in the past. After the install, I did the obligatory reboot and was shocked to see the blue screen of death. Yep, I said it, and you can see it below.

I immediately had a clue of the cause because I remember hearing that there was a Service Pack released for Virtual PC 2007. It would make sense that Windows 7 would probably need something that was part of that Service Pack. Anyway, I was easily able to repair the system and Windows 7 was working again.

After downloading and installing the Service Pack, which is available here, I attempted to install the Virtual Additions and it worked directly from the menu, which was good sign. After the reboot of Windows 7, I was greeted with the login screen. So lesson learned, you want to confirm you have the latest version of Virtual PC before doing any installs of Windows 7.
