If you have been hit with a similar problem, this is the post for you. Below you will find several methods to solve the problems resulting in your computer’s mouse highlighting everything wherever it goes on a Windows 11/10 PC.

Why Mouse is Highlighting Everything?

There can be several reasons why your computer mouse may be highlighting everything on your screen. It can be something faulty, or maybe a Windows feature that is enabled that you are not aware of. Below is a list of all the possible reasons:

Faulty hardware (mouse or keyboard)Faulty/outdated mouse driverThe Sticky Keys feature is enabledThe ClickLock feature is enabledYou have a faulty application/softwareCorrupted system files are causing your mouse to behave abnormally

You will find methods to address all of these causes for your mouse highlighting text and everything else on your Windows computer down below.

Troubleshoot Mouse Highlighting Everything

To fix your mouse highlighting everything, perform the following tasks in the chronological order given below. These methods escalate from a less aggressive approach to a more aggressive one.

Rule Out Faulty Hardware

Start your troubleshooting by ruling out any faulty hardware. It may be possible that the button(s) on your mouse is stuck or faulty, or maybe the “Shift” button on your keyboard is pressed continuously. To troubleshoot your hardware, connect your mouse to another computer and check if it behaves similarly. If it does, it means that something is wrong with your mouse and needs to be replaced. However, if it is working fine, then you must also check your keyboard. Re-connect your original mouse to your computer and replace the keyboard. Now check to see if your issue has been resolved. If it has, means that the original keyboard was faulty. If you still experience the same problem, then you need to perform the tasks given below.

Use Mouse in Another Application

If your mouse is highlighting everything inside an app or a program, try switching apps to see if the problem persists, since it might only be app-specific. If the mouse is functioning fine on other apps, then the issue is only related to that one particular app. In that case, check the app’s settings to resolve the issue, or try reinstalling it.

Disable ClickLock

ClickLock is a feature in both Windows 10 and 11 that allows you to drag and highlight content without holding down the mouse button. However, if this feature is enabled, it may be possible that you are using it without knowing it, resulting in the mouse highlighting everything. Disable ClickLock using these steps: Once it is disabled, check to see if your problem has been resolved.

Disable Sticky Keys

Sticky Keys is another feature in the Windows operating system using which you can use shortcut keys without pressing them at the same time. Instead, with Sticky Keys enabled, you can use the shortcut keys by pressing them in a defined order. This feature can also cause your mouse to behave abnormally. Disable Sticky Keys using these steps: When disabled, check if your mouse is still highlighting everything. If it is, then you need to perform the tasks given below in order to resolve this issue.

Run Hardware and Devices Troubleshooter

The Windows operating system comes with built-in troubleshooters that automatically detect and fix issues relating to different parts, such as network, audio, Bluetooth, etc. These troubleshooters can be accessed from the Settings application. It also used to have a “Hardware and Devices” troubleshooter but was later hidden by Microsoft. That said, the feature has not been removed from the OS, which means you can still run it. Run the “Hardware and Devices” troubleshooter using these steps: Now check to see if your mouse is still highlighting things without pressing any buttons. If it is, there are still a few things you can do to fix it.

Update/Reinstall Mouse Driver

A driver is a piece of code that makes communication between the software and the hardware possible. It may be possible that an outdated or corrupted mouse driver is causing it to highlight everything in its path. For that, you can try updating your mouse’s driver, or if a newer one is not available, reinstall it. Here is a complete guide on how to reinstall/update a driver manually or automatically.

Dial Down Double-Click Speed

Another possible reason for the mouse highlighting everything is that your computer is registering the mouse clicks as double clicks. This can be avoided by adjusting the double-click speed from your Windows Control Panel. Here is how: Now repeat your actions that were causing your mouse to highlight anything and check if it resolved the problem.

Run the SFC and DISM Scans

As we mentioned at the start of this post; a possible reason for the mouse to behave this way is due to corrupted system files. You can attempt to repair any on your computer by running the DISM and the SFC scans. Here is how: Once the scans are completed, restart the computer and then check if the problem has been resolved.

Closing Words
