Very good post Ben Herila.
We all need to monitor:

for the latest guesses and botches from Microsoft.
At this moment I guess that no Microsoft consumer who has a computer which still works could possibly understand the "More Information ... Known Issues with this Security Update".
The consumer world needs detailed instruction on how to recover from this series of ludicrous Microsoft Updates to USB device drivers.
Okay, the current USB device encryption virus is really scary.
Do backup you computer to external media. Do not rely on just one backup.
