Ok, that's what I thought. For the most part, the answer is no, sfc doesn't mess with most patches. It seems that I should have done what IKnowNot did and keep a record of what sfc.exe changed and compared it to what was on my system *prior* to running sfc.

IKnowNot,
Thanks for answering my question in more detail than there is on the ceiling of the sistine chapel. That answered my question and then some. You get a gold star! now pass the damn wine
