Simple Methods for Fixing Errors in Windows 10, 8.1 and Windows 7

First, a few simple ways to solve the problem code 19, "Windows cannot run this device, since information about its configuration in the registry is incomplete or damaged," perhaps one of them will work and you will not need to perform any additional manipulations:

1. Try to perform a simple reboot of your computer or laptop. Important: In the case of Windows 10 or 8.1, it is necessary to use the "Reboot" item, and not the "shutdown" with re-inclusion, these two actions differ by results.
2. Go to the control panel. To do this, you can press keys Win + R. on the keyboard and enter Control and then click OK or ENTER. And if the keyboard does not work, run the "Run" dialog box through the right click on the Start button (in Windows 10) or from the Start menu, and then enter the Control using the on-screen keyboard, which you will find in the "Special Features" folder in the standard programs.
3. Go to "Restore" and select "Running System Recovery".
4. Check if there is a system recovery point on the date when the problem with code 19 in the device manager was not observed. When presented, select this recovery point and apply it.

   

5. If the problem occurred not with some standard device, try downloading drivers for it from the manufacturer's official website and install them. At the same time, if you have Windows 10, and drivers for previous versions of the system, try to install them anyway.
6. You can try the following method: In the device manager, right-click on the device with an error and select Delete. Confirm the deletion of the device, and then in the Main Menu of the Device Manager, select "Action" - "update hardware configuration" and check if it solved the problem.

Another method, however, is not very often triggering - the use of built-in troubleshooting tools that in Windows 10 can be found in the parameters - update and security - troubleshooting - additional troubleshooting tools, and in previous systems in the corresponding control panel item (more details: elimination Windows 10 troubleshooting).

In the list of available troubleshooting tools, select the one that matches the device with an error (if any) and start the troubleshooting agent.
