Configuration Manager clients are automatically upgraded after a ConfigMgr 2012 R2 update to CU1

Applies to: Microsoft System Center 2012 R2 Configuration Manager

Symptom


After an upgrade to Configuration Manager 2012 R2 Service Pack 1 (SP1) CU1, Configuration Manager clients are automatically upgraded to the SP1 client version.

Cause


This is a known issue in which the Configuration Manager Client Retry Task is created under Microsoft\Microsoft\Configuration Manager in Task Scheduler. After it's installed, the Configuration Manager client cannot delete the scheduled task that was created in this location. Therefore, the client is scheduled to be reinstalled every 5 hours.

Workaround


To work around this issue, delete the scheduled task that is created under Microsoft\Microsoft\Configuration Manager in Task Scheduler.
