I'm not sure about that. If this were true, why ::InterlockedIncrement( )?
The InterlockedIncrement( ) function does an atomic copy, so it's impossible for the reader thread to get an outdated value. But simply declaring the variable as volatile doesn't prevent that from happening. The only thing it does is ensuring the compiler doesn't cache the variable's values in registers and fetch it from the main memory each time it's being accessed.
