RegistryView Enumeration

Specifies which registry view to target on a 64-bit operating system.

Namespace:  Microsoft.Win32
Assembly:  mscorlib (in mscorlib.dll)
public enum RegistryView
Member nameDescription
DefaultThe default view.
Registry32The 32-bit view.
Registry64The 64-bit view.

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 OpenBaseKey and OpenRemoteBaseKey(RegistryHive, String, RegistryView) methods, and the FromHandle property on a 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.
