how do I kick HP Digital Imaging off the tray

[zivshosh]

Greetings
the process is called hpqtra08.exe
but it does not appear in the registry in "Run" or "RunOnce" keys
and yet it appears in the tray every time I boot.

I did it once but can't remember how, and now I had to install the printer (HP Officejet 4500) again
OS: Windows 7 Ultimate x64
Please help
thank you

Can you disable it from the startup menu?

Bingo!
There is was in All Users Startup.
many many thanks, RogerR.
