RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters 1, True
Eu estava tentando fazer algo semelhante - atualizar uma configuração de registro para o menu Iniciar e, em seguida, imediatamente o menu Iniciar reflete as alterações.
A solução desta questão do MSDN funcionou perfeitamente para mim.
You could try broadcasting a
WM_SETTINGCHANGE
message. For example:
class Program
{
[DllImport("user32.dll", SetLastError = true)]
private static extern IntPtr SendMessageTimeout(IntPtr hWnd, int Msg, IntPtr wParam, string lParam, uint fuFlags, uint uTimeout, IntPtr lpdwResult);
private static readonly IntPtr HWND_BROADCAST = new IntPtr(0xffff);
private const int WM_SETTINGCHANGE = 0x1a;
private const int SMTO_ABORTIFHUNG = 0x0002;
static void Main(string[] args)
{
SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, IntPtr.Zero, null, SMTO_ABORTIFHUNG, 100, IntPtr.Zero);
}
}
Altere a resolução da tela e escolha a opção de reversão. Sua resolução permanecerá a mesma e o plano de fundo terá mudado.
Como alternativa, desconecte e reconecte o cabo da tela.
