PowerShell DSC broken in KB3176934

On August 23, Windows update KB3176934 released for Windows Client. Due to a missing .MOF file in the build package, the update breaks DSC. All DSC operations will result in an “Invalid Property” error.

1. If you are using DSC from or on any Windows client, take the following steps:
   Uninstall the update if already installed. From elevated PowerShell prompt type

   wusa /uninstall /kb:3176934

2. If using WSUS, do not approve the update. Otherwise, Use Group Policy to set the ‘Configure Automatic Updates’ to ‘2 – Notify for download and notify for install’ as described in this Microsoft Support article.

A fix for this issue will be included in the next Windows update which is due out 8/30/2016.

We apologize for any inconvenience that this might cause.

Regards,

The PowerShell Team
