Owning a PC means having to deal with a multitude of errors that you or you may not understand. This is true if you’re just an average computer user who relies on their computers for day-to-day use, whether at work or school. Computers contain drivers within. These drivers are files within the system that make sure that your PC’s operating system smoothly communicates and works well with your hardware devices (these are devices usually externally connected like a mouse, keyboard, printer, scanner, etc.).

If you own a PC, you probably own at least one of these hardware devices. Sometimes, these drivers fail, and this is problematic for the users. External devices can no longer function well because the communication between the device and the PC’s OS is somehow cut off. When this happens, this would be shown to you as Code 19 Error.

Part 1. Overview of Code 19 Error

Code 19 Error usually results from an error with the configuration information. This eventually leads to the failure of hardware devices from functioning along with the operating system. Changes within the registry could also affect the drivers. If you’ve recently installed or uninstalled a new operating system or performed an update, then notice the change within your PC thereafter; it may be the cause. You might also notice the error pop up multiple times when a particular hardware device is connected to your computer. This error could also be seen when your computer becomes sluggish or freezes upon the click of the mouse or a press on the keyboard.

The recommended fix of Windows for this error is to uninstall then reinstall the drivers. But there are also other existing ways to go about this problem. Keep on reading to find out how you can fix Windows Error Code 19.

Method 2. Use System Restore

System Restore is a built-in feature created by Windows. This unique tool allows users to backup their system at a certain point in time. This way, if ever something goes wrong, they can always go back to a previous state of the system at a certain point in time. This is essential when doing troubleshooting on your computer. If ever something goes wrong, you can revert your system to an earlier version.

By the end of Step 3, your issue of Code 19 will be solved if iTunes software was the real reason behind it! But if the iTunes software is not the reason, you can try resolving the error by switching to the next method.

Method 6. Run a Hardware & Device Troubleshooter

Sometimes, the Code 19 error may occur due to a hardware issue in your PC. So, in order to fix it, you must run the Hardware & Device Troubleshooter. It is basically a built-in troubleshooting utility of Windows that helps you resolve any issue with the hardware or external drives of the computer. For running a Hardware & Device Troubleshooter, you need to:

Step 1. Press Windows + I key. This will open up the Settings app on your screen.

Step 2. Now, navigate to Update & Security and then move to Troubleshoot.

Step 3. On the right panel, find the Hardware and Devices option and tap on Run the Troubleshooter, as shown below.



As always, create a system restore point or backup for your device before proceeding with any troubleshooting methods. This will avoid the unnecessary stress of any errors you might create when you attempt to fix the issue.

Your computer contains a lot of drivers to run your hardware devices. Sometimes, they become corrupt or go missing. This is usually from a system crash or a recent update or upgrade of your PC’s operating system. This may seem frustrating because it will disable you from taking control of your external device. Any of the methods above should help you fix this issue.
