  2. Code 43 My Microsoft 1000 wireless mouse

    Hi,

    Thank you for posting your query in Microsoft Community.

    I understand your concern regarding the issue that you are facing.

    Error Code 43 is a Device Manager error that means the following:

    Windows has stopped this device because it has reported problems. (Code 43)

    When you get this error with USB devices it’s because one of the drivers controlling the device notified the operating system that the device failed in some manner. This can be because of corruption in one of the loaded drivers and the driver
    cache needs to be flushed.

    Method 1: Troubleshoot

    Windows 10 has a built-in troubleshooter to check and fix issues with hardware and devices. I would suggest you to run this troubleshooter to check if the issue is with your touch Screen. Refer these steps:


    • Press Windows key +X, select Control panel

    • Change the view by option on the top right to Large icons

    • Click on troubleshooting and click on the view all option on the left panel

    • Run the Hardware and devices troubleshooter

    Method 2.

    I suggest you to manually update the Mouse driver from the Device Manager.

    1. Right click on Start button and click on Device Manager.

    2. Search for Mice and other pointing devices from the list of devices.

    3. Expand Mice and other pointing devices.

    4. Uninstall the mouse driver and reinstall the latest driver from manufacturer website.

    Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.

    Thank you.
