After upgrading my Z3100ps drivers and firmware and installing the Printer Utility, I used the Add/Remove Programs dialogue in WinXPPro to deinstall the HP EZ-Printer Care applet. However, it stil shows up in my task bar, and I occasionally get an informational message from it.
I've tried MSConfig, as well as looking for it in the Startup folder, but have not been able to find how to get rid of it. Any ideas, or should I just leave it as is?
