I uninstalled SQL Server from control panel and then ran the discovery tool.
It shows I still have
Sql Server 2008MSSQLSERVERDatabase Engine Services1033Express Edition
Sql Server 2008MSSQLSERVERMSSQL10.MSSQLSERVER
SQL Server Replication1033Express Editiono
MSSQLSERVERFull-Text Search1033Express Edition
MSRS10.MSSQLSERVERReporting Services1033Express Edition
Management Tools - Basic1033Express Edition
Looks like I do have an install remaining.
Now how do I remove it completely.
