If the mouse wheel does not work, you can try the following methods to troubleshoot and repair: 1. Check the connection and power supply to ensure that the wireless mouse has power, the interface is plugged in or replace the cable; 2. Restart Windows Explorer and mouse services to resolve system conflicts; 3. Update or reinstall the mouse driver through the device manager, and the brand mouse recommends to download the latest driver on the official website; 4. Advanced operations can check whether the Start value of the mouhid service in the registry is 3, and ensure that the computer is restarted after the settings are correct. If the above steps are invalid, it may be caused by the damage to the mouse hardware. It is recommended to replace the test.

It is really annoying that the mouse wheel does not work, especially when browsing web pages or processing documents. Generally speaking, this problem may be caused by software setup, driver problems, or hardware failure. Below I will tell you how to check and repair it from several common angles.

1. Check the basic connection and power supply

Sometimes the problem is actually very simple, such as the wireless mouse is out of power or the connection is unstable. Confirm first:

• Is the mouse powered up normally (especially wireless models)
• Is there any USB port plugged in? Try changing another port
• If it is a Bluetooth mouse, see if it is a successful connection

If it is a wired mouse, check if the USB cable is obviously damaged. You can also try to plug it into another computer to test whether it is a problem with the mouse itself.

2. Restart Explorer or Mouse Service

The Windows system occasionally experiences temporary glitches, causing some peripheral functions to be abnormal. You can try the following:

• Press Ctrl Shift Esc to open Task Manager → Find "Windows Explorer" → Right-click to select "Restart"
• At the same time, you can try restarting the "Mouse Pointing Device Service":
  • Press Win R to enter services.msc
  • Find Mouse or Pointer Devices related services, right-click and select Restart

Doing so often resolves some temporary system conflicts.

3. Update or reinstall the mouse driver

Driver problems are also a common reason for the failure of the scroll wheel. You can do this:

• Press Win X to select Device Manager
• Expand Mouse and Other Pointer Devices, right-click on your mouse device, and select Update Driver or Uninstall Devices
• After uninstalling, restart the computer, the system will automatically reinstall the driver

If you are using a branded mouse (such as Logitech, Razer, etc.), it is recommended to download the latest driver installation package to manually update it.

4. Check registry settings (advanced operations)

Sometimes, the mouse configuration in the registry is modified incorrectly, which can cause the scroll wheel to fail. This method is suitable for friends who know a little bit about computer basics:

• Press Win R to enter regedit to open the registry editor
• Positioning to path:
  計(jì)算機(jī)\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mouhid
• Make sure the value of the "Start" item on the right is 3 (indicates loading on demand)
• If not, double-click to modify it to 3 and restart the computer

?? It is recommended to back up the current settings before modifying the registry to avoid other problems caused by incorrect operations.

Basically these common solutions. If you have tried all the above methods but still can't work, it may be that the mouse itself has broken hardware, such as the roller micro-moving contact is poor. You can try it at this time.
