Changing the color mode using the registry can cause color retention on the taskbar, which is really too junk for Windows 11
On Windows 10, after changing registry, Windows calls
SendNotifyMessage with WM_SETTINGCHANGE and "ImmersiveColorSet"
I tried, but nothing happened. I can easily switch on Windows10 by simply modifying the registry key. This problem still exists in Windows11 22H2 taskbar
C#
[DllImport("user32.dll")]
private static extern bool SendNotifyMessageW(int hWnd, int Msg, IntPtr wPARAM, IntPtr lPARAM);
...
const int HWND_BROADCAST = 0xffff;
const int WM_SETTINGCHANGE = 0x001A;
bool res = SendNotifyMessageW(HWND_BROADCAST, WM_SETTINGCHANGE, new IntPtr(0), Marshal.StringToHGlobalAnsi("ImmersiveColorSet"));
...
Is there a problem with that? It didn't solve the problem.
Solved, thank you！
