Fix 1: Check for hardware issues

Before addressing our mouse left click not working problem, we might have to look out for potential hardware issues.

  1. Plug your mouse in a different USB port and see if the right click works normally:
    If yes, then the previous port is to blame.
    If no, move on to the next step.
  2. Try a different (and functioning) mouse on your computer and see if the right click works normally:
    If yes, then you might have to have the faulty mouse repaired or change a new mouse.
    If no, then move on to Fix 2.

Fix 2: Run DISM

DISM (Deployment Image & Servicing Management) is a tool in Windows that helps us fix Windows-corruption-caused errors. Sometimes this left-click-on-mouse-not-working problem happens because of corruption and misconfigurations on our computer. If that’s the case, we’ll have to run DISM to check and fix the error.

  1. On your keyboard, press the Windows logo key and type cmd. Then right click on Command Prompt and click Run as administrator.
  2. Type the following command and press Enter:
    DISM.exe /Online /Cleanup-image /Restorehealth

    Wait a while for the whole process to finish.

  3. Type sfc /scannow and press Enter.
  4. Restart your computer, then check to see if the left click works properly. If yes, then great! If the issue persists, you should try Fix 3, below.

Fix 3: Update your mouse driver

This problem may occur if you are using the wrong mouse driver or it’s out of date. So you should update your mouse driver to see if it fixes the problem. If you don’t have the time, patience or skills to update the driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

You can update your drivers automatically with either Free or the Pro version of Driver Easy. But with the Pro version it takes just 2 steps (and you get full support and a 30-day money back guarantee):

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click Update All to automatically download and install the correct version of ALL the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
    You can also click Update do it for free if you like, but it’s partly manual.
  4. Restart your computer and check if the left click not working on mouse problem has been resolved. If yes, then congrats! If the issue remains, please move on to Fix 4, below.

Fix 4: Create a new user account

A corrupted user account can also be responsible for this mouse click problem. So we might have to create a new user account and see if it gets fixed:

  1. On your keyboard, press the Windows logo key and type account, then click Add, edit, or remove other people.
  2. Click Add someone else to this PC.
  3. Follow the on-screen instructions to create a new user account.
  4. Log in your Windows with the new account and see if your mouse works properly now.
