My system: win7 x64, Sql server 2005 express, SQL Server 2005 Service Pack 3 Security Update(KB970892), Error Code: 2B33

The update failed to install on my windows, I searched by google and microsoft, but don’t find useful solution.  I run the Sql Server Configuation Manager and found the SQL Server(SQLEXPRESS) and SQL Server Browser service are not runing, start them and reinstall the update, resolve it.
