Cancel an Automatic Update (XP)

Installed FP9 the other day no probs… Microsoft now wants to install a Flash player security update (KB913433) for me, how kind, however it always says it fails to install every time it tries - im guessing because I swapped FP8 for 9. So, is there anyway to skip the update, i.e. tell it not to try again?? Its annoying on power down since I have to click the different Turn Off option, plus it keeps trying everytime I turn the Pc on…
