For example, the 32-bit InprocServer32 key is not relevant for 64-bit applications, so the InprocServer32 key is not reflected to the 64-bit registry view. In specific cases, writes to a key are not reflected if the key has some bitness dependency.
ACTIVEREPORTS 7 REGISTRY KEYS UPDATE
Updates to the keys are reflected when the update completes and the handle to the key closes. Most of the keys under the classes root are in this category. Typically, this process keeps two separate physical copies of the same registry keys in both views in the registry, and is called registry reflection or registry mirroring. When a component writes data in the system registry, WOW64 analyzes the information and makes a copy of the data in the alternate view of the registry when appropriate. For example, a 32-bit OLE server that can serve requests from both 32-bit and 64-bit clients could make its 32-bit registry data available to the 64-bit view of the system registry. It can be useful for 32-bit and 64-bit applications to share specific registry key values that are normally written to separate registry views. Therefore, the file association information is preserved for the most recently installed application. The registry reflector copies this information into the 32-bit registry, so both 32-bit and 64-bit applications launch the 64-bit version of Winword.exe for. An administrator installs 64-bit Office, which registers 64-bit Winword.exe to handle.The registry reflector copies this information into the 64-bit registry view, so both 32-bit and 64-bit applications launch the 32-bit version of Winword.exe for.

doc registration from the 64-bit registry view into the 32-bit registry view. After a clean installation of 64-bit Windows, 64-bit Wordpad.exe is registered to handle.Registry reflection uses a "last writer wins" policy as illustrated in the following example: For a list of registry keys that are redirected, shared, or reflected, see Registry Keys Affected by WOW64.

For example, reflection is not enabled for the HKEY_LOCAL_MACHINE\System key. Reflection is not enabled for shared registry keys or for registry keys that are not redirected. The reflector copies COM activation data for Local servers between the views, but it does not copy in-process data because 32/64 in-process data mixing is not permitted on 64-bit Windows. Note that this gives rise to a possible race condition: if more than one process changes the reflected key, the last RegCloseKey call determines the key's final value. Each view has a separate physical copy of each reflected registry key, one for the 32-bit registry view and the other for the 64-bit registry view.Ī reflected key is copied when a key is closed by calling RegCloseKey. The process of registry reflection copies registry keys and values between two registry views to keep them synchronized. However, the values of some registry keys must be the same in both the 32-bit and 64-bit views. The registry redirector isolates 32-bit and 64-bit applications by providing separate logical views of certain portions of the registry on WOW64.
