The registry values associated with the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole key control the default launch and access permission settings and call-level security capabilities for COM-based applications that do not call CoInitializeSecurity.

Only administrators, the object creator, and the system have full access to this portion of the registry. All other users have read-only access.
