Solution: CPF Tray Icon does not appear on the task bar

This problem is because of a bug in Microsoft Window XP. To fix the issue, you need to disable UPNP service.

As workaround, you can download http://www.grc.com/files/unpnp.exe and disable UPNP. Or you can read the following page for all known workarounds : Systray icons missing

Good luck,

I can’t see the icon either. cmdagent.exe is working, and windows security centre detects comodo as operational. However, comodo [cpf.exe]will not start up, and neither can i uninstall it, using add/remove, or uninstall. Where do i go next?

I just discovered this problem. However, I am on Vista Home Premium, not XP. The CPF tray icon has been present for months. Suddenly, today, I noticed it was not there, and I cannot access CPF to modify its parameters or shut it off temporarily. Please let me know how to get at CPF’s configuration once again.
