Additional information!

If you have SQL Server Management Studio installed on your server, you can open up SQL Server Management Studio using Run As Administrator, connect to the WID using the string below with Windows Authentication:

WID2008 = ‘np:\\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query’

Then you can expand Databases, and see if any other databases are installed on the system besides the system databases (Master, model, msdb, and tempdb) and the WSUS Database (SUSDB). If there are, simply right click the SUSDB and choose properties and look for the location of the data files. Make a note where they are, and then cancel out of the properties and right click on the SUSDB and choose Detach Database. This will make the SUSDB database go away from within the SSMS console. Close of SSMS and browse to the location of where your SUSDB was located and delete the SUSDB.mdf and SUSDB.ldf.
