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 and hope your left click works normally now.

    Fix 3: Update your mouse driver

    A corrupted/missing/outdated mouse driver is one of the common causes of your left-mouse-click-not-working problem. So you should update your mouse driver to see if it gets fixed.

    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.
