On the 64-bit version of Windows, portions of the registry are stored separately for 32-bit and 64-bit applications. There is a 32-bit view for 32-bit applications and a 64-bit view for 64-bit applications.
You can specify a registry view when you use the RegistryKey.OpenBaseKey(RegistryHive, RegistryView) and RegistryKey.OpenRemoteBaseKey(RegistryHive, string, RegistryView) methods, and the RegistryKey.FromHandle(Microsoft.Win32.SafeHandles.SafeRegistryHandle, RegistryView) property on a Microsoft.Win32.RegistryKey object.
If you request a 64-bit view on a 32-bit operating system, the returned keys will be in the 32-bit view.
