Microsoft Update: MSWU-726-windows6.1-kb2775511-v2-x64.msu is deployed via Patch Management, without any reboot settings enabled, yet the install completes and a popup is produced which forces clients to reboot.

The Default Software Update Plug-in Policy is configured to 'Never' reboot, nor are there any notifications enabled on the policy.



Patch Management 7.1 SP1, SP2 & MP1.x


The popup is produced on the Operating System level following the install.

To further clarify: This is an Enterprise Hot Fix that deploys a myriad of hot fixes. One of these fixes updates the TCPIP.sys file, which will force a reboot from the Operating System following install.

This is not caused by Patch Management Solution, for the update will throw the same popup if installed outside the product with the same run command switches for quiet & no restart.


This issue is caused by the Operating System behavior and will need to be reviewed with the vendor of the update if further troubleshooting is needed.

If the count down popup window is needed to be disabled; review the following possible methods:

  1. Run the following CMD on the Client: net stop "windows update"
  2. Stop the 'wauserv' Service on the Client's Task Manager > Services tab:

Caution: these methods for stopping a reboot are 'use at your own risk' for they may cause adverse effects on the client until the services are resumed. Be sure to test these methods before implementing in production environments.
