SYMPTOMS

On a Microsoft Windows XP Embedded-based device, you may be prompted to type your password to resume the device from standby. You experience this problem if the following conditions are true:

  • The time in the Turn off Monitor box is less than the time in the Wait box.


Notes

    • The Turn off Monitor box is in the Power Options Properties dialog box.
    • The Wait box is on the Screen Saver tab in the Display Properties dialog box.
  • The On resume, password protect check box is not selected on the Screen Saver tab in the Display Properties dialog box.


CAUSE

This problem occurs because the ScreenSaverIsSecure registry entry is missing from the following registry subkey:

HKEY_CURRENT_USER\Control Panel\Desktop


RESOLUTION

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this problem, use one of the following techniques:

  • In Windows XP Embedded Target Designer, configure the Display Control Panel component by adding the ScreenSaverIsSecure registry entry as the REG_SZ type under the following registry subkey:

    HKEY_CURRENT_USER\Control Panel\Desktop

    Then, set the value of the ScreenSaverIsSecure registry entry to 0.
  • In Windows XP Embedded Target Designer, expand Extra Registry Data, and then add the ScreenSaverIsSecure registry entry as the REG_SZ type under the following registry subkey:

    HKEY_CURRENT_USER\Control Panel\Desktop

    Then, set the value of the ScreenSaverIsSecure registry entry to 0.
  • In the Windows XP Embedded runtime, click to select the On resume, password protect check box, and then click to clear the On resume, password protect check box.


STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
