By | March 9, 2022

Don’t let mouse sensitivity ruin your day.

Having your mouse sensitivity change randomly in Windows 10 is one of the most frustrating issues, especially if you play video games, work on designs, or use settings with multiple displays.

Before you order a new mouse so you don’t lose your in-game rankings or miss a deadline, try the solutions we’ve listed below.

Quick Fix

Before we move on to more complex solutions, try these fixes:

  • Disconnect and reconnect the mouse.
  • Connect your mouse using a different port to make sure your problem is not caused by USB port not working.
  • Connect your mouse to another PC or laptop to check if the problem persists.
  • If you are using a Bluetooth mouse, make sure you are within range.
  • Replace the mouse battery.
  • Check if you accidentally touched the touchpad.

If neither of these is causing the mouse sensitivity issue, we can move on to the more complicated solutions listed below.

Check Mouse Settings

To check your current mouse settings, follow these steps:

  • Click Start, then open Settings > Devices.
  • On the left panel menu, select Mouse.
  • Use the slider to adjust the cursor speed. You should see the changes in real-time.

Turn off Increase Pointer Precision

You can control these settings using the Control Panel. Here is how you can do it:

  • In the Start menu search bar, search for control panel and choose the most suitable.
  • Click Hardware and sound > Devices & Printers > Mouse.
  • Open tab Pointer Options.
  • Uncheck Enhance Pointer Precision.

Check Your Mouse App

Some manufacturers have their own applications to use with their mouse. The advantage of this app is that you get more control over your mouse as you can change the function of the buttons, customize the LED lights, or create profiles. Sometimes, these apps can interfere with system settings and make your mouse sensitivity inconsistent.

If you have a third party application installed for your mouse, open it and check the settings. Test the pointer precision to make sure everything is working properly. If not, you can delete or update it.

Run Devices Troubleshooter

You can use the Windows 10 troubleshooter to fix some of the most common problems that users experience. Even though the Hardware and Devices troubleshooter has been removed from the Settings menu, you can still access it via the Command Prompt.

Follow these steps to run the Hardware and Devices troubleshooter:

  • In the menu search bar Start, search command prompt and select Run as administrator.
  • Type msdt.exe -id DeviceDiagnostic and press Enter. This will open a window Hardware and Devices.
  • Click Advanced > Apply repairs automatically.
  • choose Next to start the troubleshooting process.

You can use Command Prompt to search for corrupted files as they can cause your mouse sensitivity to change randomly. All you have to do is type sfc / scannow in the window Command Prompt and press Enter. Windows 10 will automatically replace any corrupt files it detects.

Use System Configuration

Follow these steps to fix mouse sensitivity issues via System Configuration:

  • In the menu search bar Start, search system configuration and choose the most suitable.
  • Type msconfig.exe and press Enter.
  • On tab General, tick Load system services and Load startup items.
  • Click Apply > Ok to save changes.

Please note that if you are using your company’s laptop or PC, the changes you made using System Configuration may be reversed after you restart the device. Also, some options may not be available.

Make Your Cursor Move Smoothly

You can easily fix mouse sensitivity issues by following the solutions in this article and feeling like you’ve bought a new mouse. If you have installed a multi-display setup, you can continue the process of further customization and install applications that change the behavior of the cursor when moving it to a different screen.
