About This Download

Registry reflection in the 64-bit version of Windows 32-bit On Windows 64-bit (WOW64) copies specific registry keys and values between the 32-bit and 64-bit views of the registry to keep them synchronized, but conflicts can occur. This paper describes mechanisms for controlling registry reflection to prevent conflicts between 32-bit and 64-bit applications.

This information applies for the following operating systems:
Windows Vista
Windows Server 2008
Windows Server 2003
Windows XP Professional x64 Edition

Note: Registry reflection has been removed from Windows 7, Windows Server 2008 R2, and later releases of Windows.

What's New:
Update to indicate that Windows 7 does not support reflection and to clarify the rules for enabling/disabling reflection.

Included in this white paper:

  • Registry Reflection Behavior

  • Registry Behavior in Windows Server 2003

  • Registry Reflection Scenarios
