Change The default maximum size of XML WSUS Server

To adjust the maximum size of XML allowed per request, you will need to adjust a setting within the WSUS SUSDB database.

You can adjust this setting by running the following SQL script on the WSUS server:
==========
USE SUSDB
GO
UPDATE tbConfigurationC SET MaxXMLPerRequest = 0
==========
NOTE: You will need to run this on the WSUS/SUP. You should check to see if the SUSDB is hosted by the default Windows Internal Database (WIDS) or by full SQL. You can check the following registry keys on the SUP to determine what is hosting SUSDB:
HKLM\SOFTWARE\Microsoft\Update Services\Server\Setup\SqlServerName

Windows 7 SP1 it's not possible to patch the client because no updates are being downloaded neither from internal WSUS.

Action Plan

============

Please manually install the latest WSUS agent by hotfix and reboot
