Can you confirm:
Because you ran the update with Windows Update, when you say run the Lync powershell do you mean:
Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn SE.FQDN -Verbose
If you download LyncServerUpdateInstaller.exe from the following article and run it just to check updates, does it show updates are available?
http://support.microsoft.com/kb/2809243
I'd strongly suggest just getting this server up to date.
