Quickie: Connect to the WSUS "Windows Internal Database" with SQL Management Studio
My lab WSUS server uses the internal WSUS database instead of SQL. I need to run some queries against it and was all set convert WSUS from WID to SQL (docs.microsoft.com) when I realized you can connect to the internal database with Sql Management Studio.
Use this for the Server name in SSMS: \\.\pipe\Microsoft##WID\tsql\query
... it works great!
