How to Stop Mouse From Selecting Everything on Windows?

There are multiple things you can try to fix the issue. Let’s go through the most eminent fixes that may help you out. These fixes will work on all versions of Windows.

Fix 1 – Perform All the Preliminary Checks on Your Mouse

By preliminary checks, we mean trying the basics before going into the complicated stuff. For instance, you may – 

  • Disconnect and reconnect the mouse to your computer to check whether it fixes the issue.
  • Clean the mouse, as there may be dirt in the sensor or the buttons of your computer that may be causing the problem. 
  • Replace your mouse with another, or use your mouse on another computer to check whether the issue lies in your mouse. 

With the help of these checks, you can quickly identify if you need to replace the mouse or it can be fixed. After establishing that the malfunctioning of the mouse is a problem related to the system, you can move on to the next fix. However, if you find an issue with the hardware, we recommend you fix it and replace the mouse. 

Fix 2 – Update Mouse Drivers

Now the first thing you need to do is ensure that the mouse uses the latest version of drivers. For those unaware, drivers are the basic yet significant components of any device interacting directly with the operating system.  Using an outdated or corrupt driver may introduce several issues.

If your system uses outdated mouse drivers, issues like the mouse highlighting everything without clicking may appear easily. 

Updating drivers frequently can become an issue for users unfamiliar with the dedicated driver update application like Advanced Driver Updater. Why? Because the process of downloading and installing driver updates is quite typical on Windows. 

You are supposed to – 

Step 1 – Go to the Device Manager on your computer. (use devmgmt.msc command in the run search or look up device manager in the start menu search.)

type devmgmt msc command

Step 2 – Find the connected mouse and right-click on it.
Step 3 – Click on Update device drivers.

Step 4 – Look for drivers and install them on your PC.

Now, since the entire process is manual, one may be unable to perform it regularly. Hence the issue may appear easily. On the other hand, with Advanced Driver Updater, one can easily run a scan to find outdated drivers on the system and update them in a single click.

The best part is that a user may create a scan schedule, allowing the tool to look for updates now and then. Install the application today and see the results for yourself.

Fix 3 – Check the Configuration of Your Mouse

After you have updated the drivers, it is essential to identify if there’s an issue with the mouse configuration. There are several things that you need to take care of. Here’s how you can do it – 

Step 1 – Press Win + R to open the run search on your computer.
Step 2 – In the Run search, use the command ‘Control’ to open the Control Panel.

Step 3 – After opening the Control Panel, ensure the view is set to large icons.

Step 5 – After opening the mouse options, ensure the button sensitivity is set to the middle of the bar as it decides the probability of your double clicks. If your mouse highlights everything without even clicking, the issue lies with the buttons.

Tip : Make sure that the ClickLock is not ON. If you find the Turn on ClickLock option is checked or marked as ON, unmark it instantly, as it may cause unnecessary highlights and selections on your PC.

Once you have made the required changes, click apply and exit the settings. You can continue using the device, and the issue should be resolved. 

Fix 4 – Use Ease of Access Center to Configure Mouse

Another way to configure your mouse is to use the Ease of Access Center in the control panel. A dedicated setting allows a user to activate a window by hovering over it. It usually means a window may open without you clicking on it.

When this feature is enabled, your mouse starts highlighting everything without clicking. Hence disabling it is the best you can do. 

Step 1 – Press Win + R to open the run search on your computer.
Step 2 – In the Run search, use the command ‘Control’ to open the Control Panel.
Step 3 – After opening the Control Panel, ensure the view is set to large icons.
Step 4 – Go to the Ease of Access Center from the available options.

Fix 5 – Try Running a Troubleshooter for Your Mouse

If none of the above fixes helped you resolve the error, try running Hardware & Device troubleshooting, which allows you to find and fix the error with the system. Here’s how you can do that – 

Step 1 – Go to the start menu and look for Command Prompt.
Step 2 – Click on Run as Administrator to open the CMD window.

Step 3 – In the Command Prompt, use the command –
