10 Tech How-To

How to Install a New Mouse in Windows 10 PC

Guide 10-16402 · Updated · Step by step

This guide walks you through connecting a new mouse to your Windows 10 PC, whether it’s a wired USB, wireless, or Bluetooth model. You’ll learn the physical setup, driver installation, and how to customize the mouse settings to your liking.

What You’ll Need

  • The new mouse (with its USB receiver if wireless)
  • For wireless: fresh batteries (if required)
  • For Bluetooth: a PC with Bluetooth capability (or a Bluetooth adapter)
  • Access to a USB port on your PC
  • If the mouse came with a CD or driver disk, you may need it (though Windows usually auto-installs)

Step-by-Step

  1. Turn on your PC and log in to Windows 10 if prompted. It’s best to do this before connecting the mouse, so Windows can detect it during startup.
  2. Determine the connection type your mouse uses:
    • Wired: It has a USB cable (or PS/2, but USB is far more common).
    • Wireless (2.4GHz): It comes with a small USB dongle/receiver.
    • Bluetooth: No dongle, pairs directly with your PC’s Bluetooth.
  3. For a wired mouse: Simply plug the USB connector into any available USB port on your PC. Windows will automatically detect and install the driver. You should see a notification that the device is ready to use.
  4. For a wireless mouse with a receiver:
    1. Insert the included USB receiver into a USB port on your PC.
    2. If the mouse uses batteries, install them (check the polarity markings).
    3. Turn on the mouse using its power switch (usually on the bottom).
    4. Windows will install the driver automatically. The mouse should work immediately.
  5. For a Bluetooth mouse:
    1. Make sure the mouse has batteries and is turned on.
    2. Put the mouse into pairing mode. This usually involves holding down a dedicated pairing button (often on the bottom) for a few seconds until the LED blinks rapidly.
    3. On your PC, go to Settings (Windows key + I) > Devices > Bluetooth & other devices.
    4. Ensure Bluetooth is toggled On.
    5. Click Add Bluetooth or other device > Bluetooth.
    6. Select your mouse from the list of discovered devices. It may take a few seconds to appear.
    7. If prompted, confirm the pairing code (often “0000” or just click “Pair”).
  6. Test the mouse: Move it around to see if the cursor responds. Click the left and right buttons, and scroll the wheel. If it works, you’re done with the basic setup.
  7. Customize settings (optional but recommended):
    1. Go to Settings > Devices > Mouse.
    2. Here you can adjust the primary button (swap left/right for left-handed use), pointer speed, scroll direction, and more.
    3. For advanced options (like button remapping or DPI settings), many mice come with their own software. You can download it from the manufacturer’s website if needed, but Windows’ built-in settings cover most basic needs.
  8. If the mouse doesn’t work immediately, try a different USB port (preferably directly on the motherboard, not a hub).

Common Mistakes

  • Using the wrong port: Some older mice use PS/2 ports (round, purple/green). If you plug a PS/2 mouse into a USB port, it won’t work. Conversely, a USB mouse won’t fit a PS/2 port without an adapter.
  • Forgetting to turn on the wireless mouse: Many wireless mice have a physical power switch on the bottom. If the mouse is off, it won’t be detected.
  • Not putting the Bluetooth mouse in pairing mode: Simply turning it on isn’t enough. You must press the pairing button so the PC can find it.
  • Plugging the receiver into a USB hub: Some hubs, especially unpowered ones, may not provide enough power or stable connection. Always use a direct port on the PC if possible.
  • Ignoring battery polarity: If batteries are inserted incorrectly, the mouse won’t power on.

Tips

  • Keep the receiver safe: If your wireless mouse uses a USB receiver, store it in the mouse’s battery compartment when traveling to avoid losing it.
  • Use the manufacturer’s software: For gaming or productivity mice, the dedicated software often unlocks extra buttons, RGB lighting, and DPI adjustments that Windows doesn’t expose.
  • Adjust pointer speed: If the cursor feels too fast or slow, go to Settings > Devices > Mouse > Additional mouse options > Pointer Options tab, and adjust the motion slider.
  • For left-handed users: Swap the primary and secondary buttons in Settings > Devices > Mouse.
  • Clean the mouse sensor: If the cursor jumps or lags, clean the bottom sensor with a soft cloth.

Troubleshooting

If your new mouse isn’t working, try these steps in order:

  1. Check the basics: Ensure the mouse is turned on (for wireless), batteries are fresh and installed correctly, and the USB receiver is firmly plugged in.
  2. Try a different USB port: Unplug and plug into another port. This rules out a faulty port.
  3. Restart your PC: Sometimes a simple restart helps Windows recognize the new device.
  4. Run the Hardware and Devices troubleshooter: Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Hardware and Devices > Run the troubleshooter.
  5. Reinstall the driver:
    1. Right-click the Start button and select Device Manager.
    2. Expand Mice and other pointing devices.
    3. Right-click your mouse (it may show as “HID-compliant mouse” or the brand name) and select Uninstall device.
    4. Restart your PC. Windows will reinstall the driver automatically.
  6. For Bluetooth mice: Remove the device from Bluetooth settings and pair again. Also, ensure the mouse is not connected to another device (some mice can only be paired to one device at a time).
  7. Check if the mouse works on another PC: If it doesn’t, the mouse itself may be defective. Contact the manufacturer for support.

Frequently Asked Questions

My mouse is plugged in but the cursor doesn’t move. What should I do?

First, try a different USB port. If that fails, restart your PC. If it still doesn’t work, go to Device Manager, uninstall the mouse driver, and restart. If the issue persists, test the mouse on another computer to see if it’s a hardware problem.

How do I connect a Bluetooth mouse to Windows 10?

Turn on the mouse and put it in pairing mode (usually by holding a button on the bottom until the LED blinks). Then go to Settings > Devices > Bluetooth & other devices, turn on Bluetooth, click “Add Bluetooth or other device,” select Bluetooth, and choose your mouse from the list.

Can I use a wireless mouse without the USB receiver?

If the mouse supports Bluetooth, yes. Otherwise, no—the USB receiver is required for the connection. Some mice support both, but most 2.4GHz wireless mice need their specific receiver.

Why is my mouse cursor moving erratically or jumping?

This is often due to a dirty sensor, a reflective surface, or low batteries. Clean the bottom of the mouse, use a mousepad or a non-glossy surface, and replace the batteries if they’re low.

Do I need to install drivers for a new mouse?

For most standard mice, Windows 10 automatically installs a generic driver that works immediately. For advanced features (like extra buttons or adjustable DPI), you may need to install the manufacturer’s software, but it’s not required for basic use.

How do I change the mouse pointer speed in Windows 10?

Go to Settings > Devices > Mouse > Additional mouse options > Pointer Options tab. Adjust the “Motion” slider to your preferred speed. You can also enable “Enhance pointer precision” for more control.
