Automatic Mouse Switcher is described as 'Scans for mouse/touchpad devices being added or removed and automatically changes mouse speed - you can virtually have different mouse speed settings for touchpad and external mouse' and is an app in the os & utilities category. There are four alternatives to Automatic Mouse Switcher for Windows. The best Automatic Mouse Switcher alternative is Mousemux, which is free. Other great apps like Automatic Mouse Switcher are EitherMouse, AutoSensitivity and Pluralinput.
MouseMux simplifies collaboration by transforming PCs into multi-user systems with added pointer devices and optional keyboards. It allows users to interact independently or simultaneously with different programs on the same desktop, fostering non-interfering collaboration.
AutoSensitivity allows you to define different mouse sensitivities (speeds) for your touchpad and mouse and automatically switch between them (based on mouse connect / disconnect).
It will change mouse speed automatically (when it detects movement/activity from a device) rather than on device connection/disconnection. This means that you don't have to disconnect your mouse to have your touchpad's preferred sensitivity, for example.
