What to do if the Mouse left-click button is not working on Windows 10

If you are using a dedicated mouse with either a desktop computer or a laptop and you suddenly find the mouse left-click button not working on Windows 10 PC for some reason, read on as this post will give you a couple of options you can try if your mouse or touchpad left-click is not working. Note that in some of these options you might have to use the left-click button which isn’t working like in this case. In the meantime, you can just use Touch if your device has this kind of function or use another mouse or the Arrow/Enter keys to navigate your device.
Here are some suggestions you need to check out if the left mouse button is not properly working on your Windows 10 PC or laptop. Before you proceed with the troubleshooting steps laid out below, you can try using that mouse on another computer and check. Once you’ve done that, make sure that the mouse has been correctly set. To be more specific, you have to select the left-click as the primary button – to do so, just open Windows Settings then go to Devices > Mouse.

After that, select Left from the drop-down menu on the right-hand side where it states to “Select your primary button” then check if the problem’s now fixed if not, use the following options.
Option 1 – Restart the Windows File Explorer
Restarting the Windows File Explorer is most likely the easiest and uncomplicated thing you can try.

Tap the Ctrl + Shift + Esc keys on your keyboard to open the Task Manager.
Next, use the down arrow button to select the Windows Explorer and then use the Tab key to select the option to Restart.
After that, click on the Enter button.

Option 2 – Try changing the USB Port
You can also try changing the USB port to fix the issue. There are times when for no reason, it can help resolve the problem.

Option 3 – Reinstall or update the Mouse driver
The problem may be caused by a corrupted or an outdated driver. So you have to update or reinstall the mouse driver. How? Follow these steps:

Open the Devices Manager from the Win X Menu.
Then locate the Mouse and other pointing devices and right click on the mouse driver to open the Properties.
After that, switch to the Driver tab and click on the Uninstall Device button.

Follow the screen option to completely uninstall it.
Finally, disconnect the mouse and plug it back in to reinstall the mouse driver.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.
Option 4 – Try checking the Mouse Properties

Pull up Settings then go to Devices > Mouse > Additional mouse.
From there, the Mouse Properties will be opened. Click on the Buttons tab and check the option “Turn on Click Lock” and click the Apply button.
After that, uncheck this option and then click the Apply button again and see if it has fixed the problem or not.

Option 5 – Try creating a new User Account
There are times when a corrupt user account could cause such problems on the computer. This is why you have to simply create a new User Account.
Option 6 – Try running the DISM tool
The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

Open the Command Prompt as admin.
Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 7 – Put your system in a Clean Boot State
Putting your PC into a Clean Boot State helps you in checking if the problem is caused by some third party app. To rule out this possibility, follow the steps below.

Log onto your PC as administrator.
Type in msconfig in the Start Search to open the System Configuration utility.
From there, go to the General tab and click “Selective startup”.
Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.

Next, click the Services tab and select “Hide All Microsoft Services” check box.

Click Disable all.
Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

From the “Start” menu, go to System Configuration.
After that, switch to the General tab and click the option for “Normal Startup”.
Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
Then find and click “Enable all” and if prompted, you have to confirm.
Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
Restart your PC when prompted.

Option 8 – Try uninstalling software you recently installed
If you have installed a program recently or a driver like a graphics driver or audio driver, you can try uninstalling it. In most cases, most driver or software installed might be causing the problem. After that, restart your PC and check if it has fixed the issue or not.
