Trust me, you are also helping the company that employs you. I realize I am not exactly your top 100 customer but if you know the sales business, it's little slips like these that generate an overall bad reputation.
I tried to remove the current Xerox drivers on our windows 7 machines but I didn't see them in the list. I think it's because the drivers did not install in the first place.
Just to make sure, I did the following thing: We currently use a netbook with Vista installed on to which we send the print requests, I installed one of our Windows 7-64 copies on it, meaning there's no way this computer, with a fresh reinstall, could have a faulty Xerox driver in it, "blocking" the "good" driver. I even made sure I don't hook up the printer physically until the downloaded Win7-64 driver is asking for it. The result:
Same thing! I can't copy paste the message but what it basically says is that these drivers Xerox made available for Win7 64 bit are Kernel Mode and Win7 64 bit does not like them, apparently.
