title: KEY_WOW64_32KEY and KEY_WOW64_64KEY
body: <p>Apart from the <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms724878%28v=vs.85%29.aspx" rel="noreferrer">MSDN reference</a>, I want to know what these keys do? Does <strong>KEY_WOW64_32KEY</strong> means that a 32-bit app on x64 OS will access the <strong>WOW64 Registry Tree</strong> ? And does <strong>KEY_WOW64_64KEY</strong> means that a 32-bit app on x64 OS will access the normal Registry Tree and not the <strong>WOW64 Registry Tree</strong> ? What if I have to access some keys which I do not know whether lies in the WOW64 or normal Registry Tree ?</p>
