I've experienced this issue on Server 2012R2. In the end, after attempting to just disable the tasks with Autoruns, I ended up using the Catalyst Uninstaller to remove the Catalyst Control Center entirely. This seems to be the only solution to the problem.
As for why the problem exists in the first place, it's anyone's guess. I believe the issue stems from the CCC being dependent on .NET 3.5, which isn't installed by default in Windows 8/8.1 or Server 2012/2012R2. Bizarrely, the installation does not fail if that component is missing on the system. Instead, the application is installed, and it attempts to generate native images of itself, without the necessary pre-requisite .NET version. In the end, the native images that are generated are .NET 4/4.5, and not compatible with the 3.5-based application. This in turn causes the process to hang up and become unstable.
Uninstalling and reinstalling the CCC does not seem to fix this issue either.
