Oh - yeah - I once had a situation where Windows updated my video driver. I had to undo that, not just for Poser. My games broke.

I no longer let windows update without asking my permission, and I review the items and veto what I don't want.

I had the exact same problem with windows update and my video driver.  The only thing I do now in windows are the security updates.  When it comes to optional updates then I'm really picky to the point where "If it's not broke.. don't fix it."
