If I may ask, are these customers corporate customers or private clients ? For as far as I know, it would be somewhat unusual for private clients not to have ANY Windows patches beyond XP3. For WIN XP (home) I still have IE 7, not that I use it much. I never liked IE 8, and I never bothered with IE9 if it's even available ! Java is a different matter. I have seen plenty of people with outdated versions. In corporate situations that might actually make sense. There can be very different requirements for private clients vs. corporate customers, especially where large corporations are concerned.
