Failed to update SQL Server 2008 R2 RTM to SP3
I saw a SQL update in Windows Update pulled from our WSUS server, Security update for SQL Server 2008 R2 Service Pack 3 and not realizing that it's an cumulative update, it managed to update the SQL server to 10.50.6220 (SP3 = 10.50.6000) without any error. I'm guessing probably some issue with the original SP3 setup. I'll update here again if I face any issue when we schedule to update the other SQL server.
