I am receiving the message that my computer has recently recovered from an unexpected shutdown. Actually it is happening on two of my PCs that are both running Windows 7 and Office 2007. Both are aslo running Avast for virus protection. One PC was purchased about 3 months ago and the other is over 3 years old so I do not believe this is a driver issue. The problem began on both machines immediately after each received the latest updates from Microsoft although they received them on different days. These updates contained 16 patches that were mostly critical security updates and none contained driver updates. The attached dump files are from the newer of the two PCs.
