RtlSetProcessIsCritical is yet another undocumented function hidden in the Windows kernel. It is one of the few which do not have a kernel32 equivalent. However, Microsoft has a good reason to not document this function - it should not be used in any application for any purpose whatsoever. I simply cannot imagine a circumstance where this function would actually come in useful. I am not responsible for any side-effects of calling this function on your computer. It may cause extreme system instability. The example is only presented as "proof-of-concept".
