Assume that the ExecutionPolicy Group Policy Object (GPO) defines one or both of the following policies in a Microsoft Exchange Server 2013 environment:

  • MachinePolicy

  • UserPolicy

In this situation, when you install any cumulative update or service pack for Exchange Server 2013, the Exchange Server 2013 Setup fails when you run the Readiness Checks.


This issue occurs because the Exchange Server 2013 Setup disables the Windows Management Instrumentation (WMI) service during the upgrade process. However, when either MachinePolicy or UserPolicy is defined, the WMI service is required to run the Windows PowerShell script that's named ServiceControl.ps1. Therefore, the installer can't continue to work if the WMI service is not running.


To fix this issue, install Cumulative Update 10 for Exchange Server 2013.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
