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.

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, then 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 1: 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.

1. Launch Run by typing it in the Search bar or pressing Windows + R on your keyboard. In the Run box, type in regedit and press OK. This will launch the Registry Editor.

2. Find and click on Computer in the Registry Editor.

3. At the top portion of the window, click File on the toolbar. Then, select Import. Choose the location where you stored a previous backup.

4. Click on the Open button. This will restore the system to its original state at a certain point in time.

Method 2: Use Registry Editor

1. Press Windows + R on your keyboard. This will launch Run. Type in regedit in the Run box and press OK. This will open Registry Editor.

2. Now, the Registry Editor window will open. Look for the HKEY_LOCAL_MACHINE folder. Under that folder, find System. Then, click on the CurrentControlSet folder. Now, go to the Control folder. Expand the folder and select Class. Then, click on {4d36e965-e325-11ce-bfc1-08002be10318}

3. Locate the files named UpperFilters, LowerFilters. Make a right-click on the icons and click Delete in the drop-down menu.

4.Exit Registry Editor and perform a reboot of your computer.

Method 3: Uninstall Faulty Drivers

Uninstalling and reinstalling faulty drivers could be the solution to your problem. Follow the instructions below to perform this:

1. Press Windows + R on your keyboard to launch Run. Or simply type it in the search bar or look for it in the Start menu.

2. The run box will now launch. Type in devmgmt.msc and click OK to open Device Manager.

3. Look for the files with a warning sign on the icon (yellow exclamation point). Right-click on the files and click on Uninstall in the drop-down menu.

4. Confirm the uninstallation by clicking Yes.

5. Do the same steps to uninstall the other files with the warning signs.

6. On the toolbar of Device Manager, click on Action. Then, select Scan for hardware changes. This will reinstall the device drivers upon the next startup.

7. Reboot your computer.

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.
