A mouse is a basic computer hardware device used to operate a computer. When you are busy working, you will feel annoyed if the mouse sensitivity changes randomly. Why does my mouse randomly change sensitivity? Maybe there are corrupt system files on your computer.

To solve mouse sensitivity changes randomly, here are several methods you can try.

How to Stop Mouse from Changing Sensitivity

How to “fix mouse randomly change sensitivity”? Below you can try some simple methods to solve this problem first.

  • Disconnect your mouse and then reconnect it.

  • Check the connection and battery if you are using a wireless mouse.
  • Connect your mouse to other computers to see if the issue still exists.

If the above simple methods cannot solve your problem, then please refer to the solutions below.

Way 1: Check Mouse Settings

You can check your mouse settings and choose a speed that works for you. This avoids the constant changes in mouse sensitivity that make you unaccustomed to the speed of your mouse cursor.

Way 2: Decreasing the Mouse DPI

When you move the mouse quickly, the sensitivity of the mouse changes completely until you set the DPI to a different value and change it back. The higher the DPI is set, the faster the cursor will fly when using the mouse.

If you want to avoid using too high a sensitivity in your game, we recommend lowering the DPI. Here are steps on how to decrease the mouse DPI.

Step 1: First, locate the on-the-fly button on the mouse. Usually, it is on the top of the mouse, located below the scrolling wheel. It is relatively small and even has the word “DPI” written on it.

Step 2: Press the button and the mouse will cycle through the preset DPI settings. If your mouse has two DPI buttons: one for increasing the mouse DPI and another for decreasing the DPI, it is more convenient than cycling through the settings.

Way 3: Run SFC and DISM Scan

If there are corrupted system files in your computer, they may cause the issue that mouse sensitivity randomly changes, too. Therefore, you can run SFC and DISM scans to fix the corrupted files.

Step 1: Run the Command Prompt as administrator. You can press Windows + R simultaneously to open the Run box. After opening the Run box, type cmd and press Ctrl + Shift + Enter.

Step 2: Type the following commands and remember to press Enter after you type each of them.

  • sfc /scannow
  • DISM.exe /Online /Cleanup-image /Scanhealth
  • DISM.exe /Online /Cleanup-image /Restorehealth
  • DISM.exe /online /cleanup-image /startcomponentcleanup

During this process, your computer will automatically replace the detected corrupt files. Once the operation is completed, the issue of mouse randomly change sensitivity will be fixed.

Way 4: Run the Hardware and Devices Troubleshooter

When you are suffering from the issue that mouse sensitivity changes randomly, you can run the hardware and devices troubleshooter to fix it without losing anything on your computer.

Step 2: Type msdt.exe -id DeviceDiagnostic in the panel and press Enter.
