Delete service / get plesk password

How do you get the Plesk administrator password in Windows:

C:\Documents and Settings\Administrator>cd %plesk_bin%
C:\SWSoft\Plesk\admin\bin>plesksrvclient -get

How do you remove a service listed in the services if it no longer exists?

C:\>sc delete MSSQL$SQLEXPRESS
[SC] DeleteService SUCCESS

This was particularily useful when trying to re-install/upgrade SQL Express.
