Have you read the EULA for Windows? They are not responsible for anything that happens on or to your computer. Ever. For any reason.
And you agreed to it when you installed Windows.
Of course the EULA is such a doc - All in MS, a de-facto monopolist's favor. That isn't sufficient to shield them from ANY liability for their products just as the release you agree to at a Parking Garage is sufficient to shield the garage operator from all liability.
The theory is that you cannot be released from liability for your fraudulent actions or gross incompetence (A constructive Fraud). These "Defects" in MS software are foreseeable, known (and in fact purposely included) and able to be corrected so I just have to think a concerted suit by knowledgeable people would stand a chance.
There are a dozen other causes of action that could be asserted in any assault on the EULA, most notably that it is against good public policy to permit such an enforced release.
