Applying update - Failure configuring - Reverting changes
A very strange thing happened today, first time I've seen this on my real or virtual machines. Luckily it happened to a VirtualBox vm for which I had several snapshots so I could revert to an earlier state and got everything back (VirtualBox vm snapshot = about the same as system image on real, physical computer).
Here's the problem description, I would like to know what happened and maybe also why this happened.
A Windows 7 Enterprise installed on VirtualBox 4.04 virtual machine, licensed and activated. A lot of software installed, used solely for testing purposes. Been up and running a few months without issues, all updates installed except SP1.
Today a normal boot produced this:

It took about a minute for Windows to run through "update operations" 1 through 92703.
After "Applying update operation" phase Windows rebooted, trying to configure some updates, finally stopping like this:

Again a reboot. Windows had totally reverted to a point after first boot. All installed software is gone, as well as installed updates and personalizations. It's just like after the first boot after installation some months ago, even showing the browser choice dialog:

As I mentioned, this is not an issue per se because I could use an earlier snapshot to put everything back, to revert Windows as it was yesterday. However, I really would like to learn what and why happened. I have never before seen a Windows installation to lose all installed apps and updates.
Any ideas welcome.
