How to Fix Code 19 Error

welcome message

What to do when the code 19 error occurs?

Code 19 error is a driver-related error code, which is generated by the Device Manager in Windows. The Device Manager, which is a Windows driver management utility, has a set of exclusive error codes that are generated when one of the following occurs:

  • When a computer fails to recognize the drivers for the device, or
  • When there are hardware problems on the system.

These error codes should not be mistaken for system error codes that are generated by software malfunctions.

What is the “code 19” error?

Before you continue!

The cause of this problem may actually reside in your Windows registry. I personally use RegCure Pro to make sure my registry is optimized and error-free.

The code 19 error pops up on the screen when the Device Manager fails to recognize an optical drive such as a CD-ROM/DVD-ROM on the system. This may occur due to corrupt drivers or corrupt Windows. It can also occur when the driver is faulty.

How to fix the code 19 error?

The missing or non-working optical drive that gives the code 19 error can be rectified by performing the steps listed below:

Step 1 – Uninstall any new software –

If the error started occurring soon after you install one or more software programs on your computer, uninstall them. If the error goes away, the problem may be caused by one of these software programs. To identify which software program caused the error, install them one-by-one. The error will start reoccurring after you reinstall the problematic software. Remove this software program and retain the rest.

If this does not fix the error, proceed to the next step.

Step 2 – Uninstall the Problem Optical Drive

1)       Right-click My Computer and then select Properties.

2)      On the Hardware tab in the System properties dialog box, select Device Manager.

3)      Right-click the problematic optical drive—marked with a yellow exclamation or a red cross next to it –and click Uninstall.

4)      Now restart the system.

The system will automatically search for and install the driver. Proceed to next step if error is still there.

Step 3 – Restore to Last known good configuration

1)      Restart the system.

2)      Keep pressing the F8 key.

3)      You will get a set of options.

4)      Scroll down with arrow keys and select “Last known Good Configuration”.

This will put the system back to the configuration kept as a snapshot by windows and once this is done the OS restarts. If it still doesn’t clear the Code 19 error then move to next step.

Step 4 – Perform System Restore

1)      Click Start and go to All Programs.

2)      Go to Accessories and click on System tools.

3)      Click System Restore and choose a date when the system was working fine.

4)      This will apply the settings of that day and restart the system.

Step 5 – Change the optical drive

If all the above procedures do not solve the code 19 error then check for the optical drive itself by swapping it with a good known drive.

Step 6 – Delete related entries from the registry

If the problem persists then there is a problem with your Windows operating system. To solve it follow the steps below. This step involves advanced editing of the registry and deleting keys that represents the optical drive.

1)    Click Start and go to Run.

2)    Type Regedit and press enter to display the Registry Editor window.

3)    Expand HKEY_LOCAL_MACHINE.

4)    Now browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}.

5)    Click on UpperFilters on the right pane and select delete and press OK.

6)    Now select Lowerfilters on the right pane and select Delete.

7)    Click OK to delete.

8)    Close the Registry editor.

9)    Restart the system.

This should solve the problem with the code 19 error, if not,  it is better to use the “Fix it” option which is an automated troubleshooting service from Microsoft or do a clean install of the operating system.
