HOWTO: Build a System with an Optional Mouse Component


The information in this article applies to:

  • Microsoft Windows NT Embedded 4.0


This article explains how to build a Windows NT Embedded 4.0 target system with an optionally attached mouse.


In order to specify that a mouse may or may not be attached to your Windows NT Embedded 4.0 target system, follow these steps:

  1. Open Target Designer and select the configuration that corresponds to your target device.
  2. In the component tree view under System\Shared System Components, select the Mouse Common component.
  3. From View menu, click Registry.
  4. In the registry view, right-click the following registry key:
  5. Click Modify. The Edit DWORD Data dialog box appears.
  6. In the Data edit field, replace the value shown with the value of 0 (the number zero). Click OK.

Note that the icon next to the ErrorControl registry key changes to indicate that you have manually changed this field.

  1. Check dependencies and rebuild.
  2. Now that the target image is built, you can redeploy your target system.

Under normal operation, you can build a system with or without a mouse. When you run a system that defines a mouse but does not include the physical mouse, an error message appears when you restart your computer. If you set the ErrorControl key to 0 (the number zero), this prevents the error message.
