I have used VBox 2.0.6 for a few months and dig it. Two days ago I decided to check out this Windows7 beta thingy and updated VBox to 2.1.2 to provide guest "add-ons". All was peachy until I rebooted the host.
"Then all went 16 bit on me."
With the installation of VBox 2.1.2, something changed with the host video. No longer was my Quadro FX770M being controlled by Nvidia drivers. Something called VGASAVE was now in control. Some may think, yeah so? (For those who have never had the pleasure of using a machine using VGASAVE, I think the only comparison would be XP on a 486. (if that were possible))
To remedy this video problem, I tried: reinstalling the Nvidia driver (with reboot); didn't help, uninstalling VBox 2.1.2 (with reboot); didn't help; reinstall Nvidia drive after uninstall VBox 2.1.2... I assume you can figure out this one...
It turns out the only way to revert this "enhanced" machine to a working system was to use M$ System Restore to the restore point prior to when VBox 2.1.2 uninstalled 2.0.6.
Being the masochist that I am, I decided to export a copy of the working registry, create another system restore point, and install a fresh copy of VBox 2.1.2 with all of the "default" settings. Reboot time...
"Then all went 16 bit on me."
So, I have decidedly nailed down the culprit. VBox 2.1.2 doesn't like my system. I exported a copy of the registry in this state. (Luckily System Restore saved me again and my system is working.)
Since I believe in open source, shareware, and freeware software, I feel I need to contribute to VBox. I would like to compare the registries and provide whatever information I can, but I am not sure which hive I should look in for comparison. (Sorry I cannot provide the entire registries.)
Thanks.

There should be tools that can compare files. As a registry file is just a plain text file, it should have no problems comparing the two.
