Wow6432Node Registry Key
The Wow6432Node registry entry indicates that you are running a 64-bit Windows version.
The operating system uses this key to display a separate view of HKEY_LOCAL_MACHINE\SOFTWARE for 32-bit applications that run on 64-bit Windows versions. When a 32-bit application writes or reads a value under the HKEY_LOCAL_MACHINE\SOFTWARE\<company>\<product> subkey, the application reads from the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\<company>\<product> subkey.
A registry reflector copies certain values between the 32-bit and 64-bit registry views (mainly for COM registration) and resolves any conflicts using a "last-writer-wins" approach.
