If a Microsoft System Center Configuration Manager task sequence that uses the "Install Software Updates" step installs a software update that triggers multiple restarts after the task sequence successfully runs the Install Software Updates task, the task sequence can fail and generate the following error message:
Task Sequence environment not found
The first restart that is initiated by the software update is controlled by the task sequence. However, the second restart request is initiated by a Windows component (typically, Component-Based Servicing) and therefore is not controlled by the task sequence. Because the second restart is not controlled by the task sequence, the task sequence execution state is not saved before the restart. When the task sequence resumes after the second restart, no state is available to continue successfully.
To resolve this issue, we recommend that you apply any updates that require dual restarts by using the usual Software Updates feature of Configuration Manager instead of using task sequences. The following software updates were reported as requiring multiple restarts. This article will be updated as more updates are reported.

Binary files in some USB drivers are not updated after you install Windows 7 SP1 or Windows Server 2008 R2 SP1
Because this second restart is not controlled by the task sequence, no execution state is saved before the restart. And, when the task sequence resumes after the restart, no state is available to continue successfully. Additionally, the Smsts.log file may contain the following message when you experience this issue:
Task Sequence environment not found
Also, clients that are running releases earlier than Microsoft System Center 2012 Configuration Manager Service Pack 1 may contain the following log entry:Note
The client computer may also be stuck in provisioning mode after the task sequence fails. To determine whether the computer is in provisioning mode, check the following registry subkey:
should be set to false
. If it set to true
, use one of the following methods to take the client out of provisioning mode:
- Use the Windows Management Instrumentation (WMI) method SetClientProvisioningMode to correctly take the client out of provisioning mode. The easiest way to do this is to run the following Windows PowerShell command:
Invoke-WmiMethod -Namespace root\CCM -Class SMS_Client -Name SetClientProvisioningMode -ArgumentList $falseOr, from an elevated command prompt, run the following command:
powershell Invoke-WmiMethod -Namespace root\CCM -Class SMS_Client -Name SetClientProvisioningMode -ArgumentList $false
- Reinstall the client.
Do not try to fix the client by changing the value of ProvisioningMode
. This action will not fully take the client out of provisioning mode.
