    Hi @崇億 張 ,

    After modifying the registry settings, notify the system about the changes using SystemParametersInfo function.

        private const uint SPI_SETGESTURE = 0x009B;
    private const uint SPIF_SENDCHANGE = 0x02;

    private const uint GESTURE_ENABLE = 1;
    private const uint GESTURE_DISABLE = 0;

    [DllImport("user32.dll", SetLastError = true)]
    private static extern bool SystemParametersInfo(uint uiAction, uint uiParam, IntPtr pvParam, uint fWinIni);

    static void Main(string[] args)
    {
        ModifyGestureSettings(GESTURE_ENABLE);

        // Notify the system about the change
        SystemParametersInfo(SPI_SETGESTURE, 0, IntPtr.Zero, SPIF_SENDCHANGE);

        Console.WriteLine("Gesture settings updated.");
    }
    static void ModifyGestureSettings(uint setting)
    {
        const string keyPath = @"HKEY_CURRENT_USER\Control Panel\Desktop";
        const string valueName = "TouchGestureSetting";

        Registry.SetValue(keyPath, valueName, setting, RegistryValueKind.DWord);
    }

    Best Regards.

    This tests works for me on Windows 10 22H2, compiled in x64 only :

    (I just saw you tagged C#, but you can use ChatGPT to convert it...)

    					const IID CLSID_NotificationSettings = { 0xD18705BE, 0xFC2F, 0x44C8, 0xAE, 0xFF, 0x1C, 0xD4, 0x9A, 0xEA, 0x8F, 0xC1 };
					INotificationSettings* pNS = NULL;
					IUnknown* pUnknown;
					HRESULT hr = CoCreateInstance(CLSID_NotificationSettings, NULL, CLSCTX_LOCAL_SERVER, IID_PPV_ARGS(&pUnknown));
					if (SUCCEEDED(hr))
					{						
						hr = pUnknown->QueryInterface(__uuidof(INotificationSettings), (void**)&pNS);
						if (SUCCEEDED(hr))
						{
							uint32_t p0 = 0;
							int64_t p1 = 0;
							uint32_t p2 = 0;
							hr = pNS->SetGlobalSetting(p0, p1, p2);
							if (SUCCEEDED(hr))
							{
								MessageBox(NULL, _T("Deactivated"), _T("Information"), MB_OK | MB_ICONINFORMATION);
							}
							hr = pNS->GetGlobalSetting(p0, &p1);

							p1 = 1;
							hr = pNS->SetGlobalSetting(p0, p1, p2);
							if (SUCCEEDED(hr))
							{
								MessageBox(NULL, _T("Activated"), _T("Information"), MB_OK | MB_ICONINFORMATION);
							}
						}
					}

    with :
