SQL Server 2005 Express SP2 Problem

I'm putting this out there to see if anyone can help me with this very puzzling issue...

I installed SQL Server 2005 Express SP2: it went very smoothly, no errors, rebooted, perfect. I uninstall SQL Server and all of the supporting programs: again no errors, rebooted, fine. The problem is that the SQL Server service is still installed and running (???). Also, all of the program groups and utilities are still installed and working.

I know I have to manually uninstall (rip out) SQL Server, but am unable to easily find the "How-To" for it. Thanks to anyone who can help.
