Random Mouse Sensitivity Changes – Fix in Windows

One of the most important elements that help us navigate the operating system and run applications is the mouse. This peripheral is somewhat delicate so it is possible to encounter problems such as its sensitivity changing randomly in Windows 10. This can be quite frustrating, since sensitivity, also called cursor speed, is an important value when browsing by the user interface of our screen.

If the sensitivity of the mouse changes randomly in Windows it will make it difficult for us to point and click in the desired position, so we will notice it especially if we are playing or working with an editing or design application. We will even notice that our experience with operating the operating system is not as optimal as one might expect. Although changing the mouse may be the first idea that comes to mind, it is recommended previously to make some adjustments in Windows that can help us solve the problem.

Causes of mouse sensitivity changes

Adjusting the sensitivity of the mouse is something we usually do to be able to feel more comfortable when using them. Not all users use the same sensitivity since this value will change depending on our tastes. In case the sensitivity of the mouse changes by itself and in a random way, it cannot be considered as something normal . The causes that originate them can be related to a hardware in bad condition in the mouse itself or problems related to the software. We can find ourselves problems due to a bad mouse configuration or due to having outdated or obsolete drivers.

Windows 10 Troubleshooter

Windows has its own troubleshooter that can help us solve some common problems that we may encounter. While the Hardware and Devices Troubleshooter tool has been removed from the Settings menu, it is accessible through the Command Prompt.

To do this we must write cmd in the search box of the Start menu. This will bring up the “Command Prompt” application that we must run as administrator . Once it appears, we must insert the following command and press “Enter” to execute it:

msdt.exe -id DeviceDiagnostic

Símbolo del sistema solucionador de problemas

In the new window click on “Advanced options”, we mark the box “Apply repairs automatically” and click on “Next” to continue. The troubleshooter will then run and fix the mouse sensitivity error or show us more details about it.

Update drivers

Drivers are a very important element of the operating system as they help you connect and communicate with a hardware device. Keeping your drivers up to date is important to avoid potential problems. Therefore, we must access the Device Manager to check it.

Press the keyboard shortcut Windows + X and select the “Device Manager” section from the menu. Here we move to the section on “Mouse” and other pointing devices. We will see our mouse connected here, so we right-click on it and select “Update driver”. On the next screen we select “Search for drivers automatically”. We follow the on-screen instructions for Windows to search for the latest version of the automatic drivers and update them if they are out of date.
