batch file - Automatically disable mouse acceleration - Windows -


i have laptop , use mouse it. don't acceleration while using mouse. have disable acceleration every time plug mouse. there way automatically disable mouse acceleration, whenever plug mouse? know u can script un udev recognizes mouse plugged , auto disable mouse acceleration... how do on windows ?

believe not possible simple batch-file. can use windows api in c++:

you can register device notifications (like plugging in usb mouse) using registerdevicenotification

handle hrecipient = hwnd; // window handle returned createwindow  guid interfaceclassguid = { 0x378de44c, 0x56ef, 0x11d1, 0xbc, 0x8c, 0x00, 0xa0, 0xc9,                              0x14, 0x05, 0xdd }; // guid_devinterface_mouse dev_broadcast_deviceinterface notificationfilter;  zeromemory(&notificationfilter, sizeof(notificationfilter)); notificationfilter.dbcc_size = sizeof(dev_broadcast_deviceinterface); notificationfilter.dbcc_devicetype = dbt_devtyp_deviceinterface; notificationfilter.dbcc_classguid = interfaceclassguid;  hdevnotify hdevicenotify = registerdevicenotification(hrecipient, &notificationfilter,                                                        device_notify_window_handle); if (hdevicenotify == null) {     getlasterror(); // error handling here }

and listen them in window's message handler (lresult callbackwndproc(hwnd hwnd, uint message, wparam wparam, lparam lparam))

switch (message) { case wm_devicechange:     switch (wparam)     {     case dbt_devicearrival:         // mouse plugged in - turn mouse acceleration off here         break;     case dbt_deviceremovecomplete:         // mouse removed - turn mouse acceleration on here         break;     default:         break;     }     break; case // ... usual window message handling

actually changing setting can achieved using systemparametersinfo described in this excellent answer.

i implemented tiny tool called accelswitcher that. available on github.
