Original product version:   Microsoft System Center 2012 R2 Configuration Manager
Original KB number:   3123029

Symptom

After an upgrade to System Center 2012 R2 Configuration Manager 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.
