System Update rubbish leftovers

[tperica]

T42, Win XP, SP2, All MS and IBM updates, Soft. install, Sys update

After I uninstall System Update, I still see service running:
"ThinkVantage System Update" referring to "C:\Program Files\ThinkVantage\SystemUpdate\UCLauncherService.exe"

Startup:referring to same folder with reg. key under.
SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Normally, in Event log I see error and seems that service is not working.

How can I get rid of this ?

cheers
