ConfigMgr 2012: Ccmeval.exe causing client corruption

I’ve discovered, on more than one occasion, that the ConfigMgr 2012 client’s ccmeval.exe, which is intended to resolve client health related issues, actually breaks the ConfigMgr client. This has happened on a Windows 8 RTM client, and I’m fairly certain that it affects Windows Server 2012 as well. You might be aware that Windows 8 and Windows Server 2012 are unsupported client operating systems with ConfigMgr 2012 RTM, but will be officially supported in Configuration Manager 2012 Service Pack 1 (SP1).

Issue


By default, when the ConfigMgr 2012 client is installed, a Scheduled Task is registered under the \Microsoft\Configuration Manager called “Configuration Manager Health Evaluation.” The command line that is called is simply ccmeval.exe, with no command line arguments. The task will run approximately around midnight (12:19 AM on my test client) every night.
