Since SMS 2003 days, we’re using CCMClean.exe to uninstall or remove the client components. Removing/Uninstalling ConfigMgr 2007 or 2012 clients using CCMClean.exe is not supported by Microsoft. “Not supported by Microsoft” !! So, what does that mean ? Well, it’s not tested (extensively) and certified by Microsoft for the products ConfigMgr 2007/2012. However, it may or may not work. In my experience, the CCMClean.exe is able to successfully remove/uninstall ConfigMgr/SCCM 2007 and 2012 client components. More details below……
