    Change Windows Regional Date Format

    I has the following code :

    Microsoft.Win32.Registry.SetValue("HKEY_CURRENT_USER\Control Panel\International", "sShortDate", "dd/MM/yyyy")


    When I click the control panel regional date properties, the date format was changed. But the desktop date at the bottom right was not changed. How can I make it change as well?

    Registry gets read ONCE when you log in or boot. It tells you to re-start most of the time, if you have credentials

    It is not usually a good idea to do these sort of changes in the registry, there are many possible issues that might arise from it; but, sometimes there is a need.

    You have to remember, as David rightly pointed out, the Registry gets loaded by Windows once, any changes to that might not get loaded immediately. A System change such as what you have, will only take effect after a reboot of the PC.

    You might be able to send a broadcast message, to inform Windows that a registry value has changed. Have you heared of the following APIs :

    BroadcastSystemMessage
    PostMessage
    SendMessage


    You could use any of those, as long as you send the WM_SETINGCHANGE constant.
