Disabling Windows Keyboard Shortcuts (Windows Embedded Standard 2009)

4/23/2012

Certain keyboard combinations may allow access to programs or features that you have hidden from the Start menu or other parts of the user interface. The keyboard combination CTRL+ALT+DELETE is normally used to display the Windows logon prompt after the computer has booted, or to display Task Manager when the computer is already logged on.

The Windows logo key by itself hides or shows the Start menu. It can be used with other keys to run or open other Windows functions such as My Computer, System Properties, the Run dialog box, or the computer locking function.

  • Use Ginastub.dll, set a policy in Group Policy Editor, or write low-level keyboard hooks. :

    You can disable just about any key combination with one of these methods. To view detailed examples and instructions, see the MSDN article about disabling keys in Windows XP at this Microsoft Web site.

  • Download and modify Ginastub.dll, a Microsoft® Visual Studio® 6.0 sample, from this Microsoft Web site.
