About the Error

When trying to use a hardware device attached to your computer, such as a USB optical mouse, your computer displays the error message for error code 20. Windows is having problems loading a device driver and is unable to use the affected device.

How I solved the code 20 error

To resolve Windows error code 20, you will have to take some very basic steps to update the drivers for the device that will not work. You should have gotten the error when trying to use a specific piece of hardware, so you will have to update the driver for that device.

Here are the steps you will need to take in order to update the device driver:

• Browse to the Device Driver on your computer.
• Locate the device that is causing the driver error to display.
• Right click on the device. This should launch the device’s Properties dialog box.
• In the dialog box, click on the Driver tab.
• Click on the button that says “Update Driver”.
• Follow all of the prompts from the Hardware Update Wizard.
• When the Wizard gets to the screen that asks you for the path to the driver, you can choose the option to let Windows automatically locate the driver.
• If Windows is able to locate the correct driver, simply follow the remaining prompts.
• If Windows is still unable to locate the correct driver, you may have to go to the device manufacturer's website to download the most current driver. If you do, save the new driver to a location you will remember.
• Choose the correct path (the location where you saved the new driver) and follow the rest of the Update Wizards prompts.
• Restart your computer.

Windows error code 20 should not happen after you take these steps. If it does reoccur, you may need to consult with the manufacturer's documentation or website to see if there are any patches or hot-fixes that address this error.
