Install Updates in Task Sequence not installing

Issue:
In spite of the fact that you have put the Install Software Updates step into your task sequence and specified that either all or only mandatory software updates be installed, the Task Sequence installs no updates but simply breezes through this section of your TS. At this point, your TS may look a bit like this:























When you first logon to your newly build machine, it won't have any updates installed on it.

Cause: 
The issue here is that while the CCM client is being installed, it isn't communicating with the SCCM server so isn't aware of what updates are available for it.

Fix:
Essentially, you need to ensure that a full UpdateScan is triggered right after the client has been installed. This will ensure the client talks to the server and sniffs out which updates are available. In order to do this you need to insert an extra step into the Task Sequence:
 

 

The text in the command line is as follows:

WMIC /namespace:\\root\ccm path sms_client CALL TriggerSchedule "{00000000-0000-0000-0000-000000000113}" /NOINTERACTIVE

 

If, for whatever reason, you need to trigger any other client actions simpy use the one of the following cmd lines:
