More information about this security update

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 How to back up and restore the registry in Windows
If an application no longer works after you install this security update, you can configure the registry to exempt the application from the update. To do this, use the following method:
  1. Click Start, click Run, type regedit in the Open box, and then click OK.
  2. Locate and then click the following subkey in the registry:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Application_name\
    Note In this step, Application_name is a placeholder for the name of the application that you want to exempt. You may have to create the Application_name subkey. To do this, follow these steps:
    1. On the Edit menu, point to New, and then click Key.
    2. Type a name for the Application subkey, and then press ENTER.

      Note The name for the Application subkey must match the name of the executable file for the application. The name must also include the three-letter extension of the executable file for the application. For example, Microsoft Office Excel uses the following excel.exe subkey:
      HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\excel.exe\
  3. On the Edit menu, point to New, and then click DWORD Value.
  4. Type AllowMessengerExecHandleFailure for the name of the DWORD, and then press ENTER.
  5. Right-click AllowMessengerExecHandleFailure, and then click Modify.
  6. In the Value data box, type 1, and then click OK.
  7. Exit Registry Editor.
