If you just turned on your computer and started surfing the web only to find out that the middle mouse button is not working. It can be very frustrating no longer being able to scroll down a webpage. I mean honestly how often do you even us the side scroll bar if your mouse has a wheel? There is a few ways you can trouble shot and try to fix the issue. Please note these are software fixes and not hardware. If your middle mouse button is truly broken due to a mechanical issue, It might be time for a new mouse or contacting the manufactures to see if it is still under warrenty.

Let us take look at a couple of different quick fixes we can do to see if these resolve the issue.

Troubleshoot the Hardware

First we have to figure out if this is a hardware related issue of a software related. So we will be checking the mouse first before we move onto and software related issues.

The quickest way to figure out if this is a mouse related issue. Is to unplug the mouse and plug it into another computer. If the mouse wheel works on the other computer then it is a software related issue with the mouse.

What happens if you don’t have another computer to use as a test? Then I suggest doing a physical inspection of the mouse wheel. If there was a recent fall or damage to the mouse wheel most likely the wheel will be bent off axis slightly. If there is a internal issue that can’t be seen with a visual inspection then you will have to open up the mouse. Which I don’t suggest at that point it will probably be better to see if there is any warranties from the manufacturer or to buy a new mouse.

Run Hardware Troubleshooter

On Windows 10 there is a built in hardware troubleshooter. That allows you to Automatica scan to see if there is any issues with the mouse. If there are any issues that the troubleshooter can resolve it will be easy and is why it is the first fix we recommend.

  1. Goto your control panel. Type control panel into the windows search bar.
  2. Select “Hardware and Sound“.
  3. Then open “Devices and Printers“.
  4. Find you mouse and right click on it to bring up the menu. Then select troubleshoot.
  5. The troubleshooter will run if it finds a fix apply it and restart your computer.

Update the Mouse Driver

If the troubleshooter didn’t work then you can try updating your mouse drivers.

  1. Using your windows search bar type in “device manager”. This will open a list with all of your devices.
  2. Find your mouse by looking for a tab labeled. “Mice and other pointing devices”
  3. Right-Click on the mouse then select update driver.
  4. Once the update is complete restart your computer.

Install Manufacturers Mouse Drivers

For most mice updating the generic driver should work. But if you are using a mouse like Razer etc then it might act up with the generic driver and you will need to install the drive from the manufacturer.

  1. Goto the manufacturer’s website of you mouse.
  2. They should have a drivers section at the top or bottom of the webpage. This changes with each manufacturer but if there is drivers available they will have it on there site.
  3. Find the driver for you model of mouse. Most companies have search functions, which make finding your model number a bit easier.
  4. Install the latest drivers for your mouse.
  5. Restart your computer when you’re done. You might need to re-configure your mouse button if you had it set up a different way previously.

Change the Registry Settings

Changing the registry is always the last attempt at fix issues. Due to the risk of causing more harm for users. Always make a back up before editing any code in your windows registry. follow the next steps very carefully.

  1. Search “registry” using your tool bar at the bottom of windows. Click registry editor.
  2. If this is your first time windows might ask for permission to make changes. Press “Yes” if asked.
  3. Within the registry there is many different drop down menus we only want to access the “HKEY_CURRENT_USERS” this is normally the second option.
  4. A New drop down menu will appear now we need to select “Control Panel”
  5. Next we need click “Desktop”. This will bring up once again more windows on the right hand side.
  6. Now we are looking for “WheelScrollLines” this list is in alphabetical order so it will be located towards the bottom of the list.
  7. Left-Click on “WheelScrollLines” and click “modify”. This should be the first option.
  8. Finally we just want to make sure that this setting is set to “3” if it is don’t do anything. If it isn’t then change it to “3”.
