I first had this happen on just one of my servers. It was annoying and was causing massive numbers of WMI entries in the event logs each time it happened. I tried to just stop and disable the ConfigMgr client, but it would be “reactivated” again by something. Recently at a client site I found it happening an a large number… so time to investigate.
I checked there were no push jobs running, but there was *something* causing it to repeat. Some digging later and I finally found the reason.
There is a scheduled task created by CCMSETUP to retry if it isn’t able to install correctly on the first attempt. Under some circumstances, this task isn’t cleaned up and so the reinstall keeps happening
