I have installed all prerequisites for KB4550964 on one WIN7 system and it has also been activated with one year ESU MAK. To brief, I have afollowed each and every steps mentioned here : https://support.microsoft.com/en-gb/help/4522133/procedure-to-continue-receiving-security-updates.
We use SCCM in our environment and have deployed KB4550964 to the subjected machine. Ran software update scan cycle a couple of times. It has been 3 hours and I still do not see the patch starting to get installed. Every functionalities of SCCM on this
box works just fine. Could you please tell us if there is anything left out to be done or how long does it generally take for SCCM to analyse before it deploys the ESUs?
