19Code 19 describes incomplete or damaged device configuration in the registry. It does not identify a failed component or a key you should delete. The device class and a recent change determine how to recover its configuration.
Device Manager Code 19
Windows cannot start the device because its configuration is incomplete or damaged. Check the correct entry before reinstalling its driver.

Find your situation
See all the clues. Choose the one that matches what you observe.
Started after installation or an update
Relate the failure to the specific driver or software before touching other devices.
It is a CD/DVD drive
Recording software and its filters have a specific path; it does not generalize to disks or keyboards.
Persists on an identified device
Reinstall only with a compatible package and a safe way to regain control of the computer.
Diagnostic signals
- ObservationSeveral devices of the same class fail
- This points toward shared configuration or software, without proving simultaneous physical damage. Do not delete class-wide filters to test it.
Step-by-step solutions
Confirm the device entry and class
Identify what removing the device would interrupt.
Open Device Manager, the affected entry and Properties > General. Confirm Code 19 and record the model, class and provider/version under Driver. If the code differs, change diagnosis.
Distinguish CD/DVD, storage, keyboard/mouse, audio or USB. If it is the boot disk, storage controller or only input method, do not uninstall it to test: arrange assistance and recovery first.
Relate the failure to a recent change
Record which driver, audio/USB utility or recording program was installed or removed before failure. If there was no known change, do not choose random software.
If it began after updating that driver, check whether its Driver tab offers Roll Back Driver. Before applying it, save work and prepare the official package and alternative input; if unavailable, go to the manufacturer.
If Code 19 disappears and it works, the driver change is implicated, not physical damage. If it persists, do not repeat rollback; review reinstallation or the CD/DVD-specific branch.
Scope the CD/DVD case
If it began after installing or removing recording software and the CD/DVD drive has Code 19, consult that program’s support and Microsoft’s optical-drive guide. A compatible program repair may be more appropriate than removing unrelated drivers.
The optical guide discusses UpperFilters/LowerFilters in a specific context. Do not copy that recipe to a keyboard, audio device, USB device, SSD or storage controller. This guide does not prescribe registry deletion: if safe measures do not change the failure, request supervised recovery with backup and confirmed scope.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Redetect only the affected device
First download the official package for the model and installed Windows version. With alternative input available, close applications using the device. Do not use third-party driver updaters.
In Device Manager, right-click the confirmed entry > Uninstall device. Do not select driver-package deletion as an additional step. Use Action > Scan for hardware changes; restart normally if Windows requests it.
If it returns without Code 19 and works, stop. If a driver is missing, install the prepared official package following its instructions. If the same code returns, do not repeat the cycle: give the manufacturer the class, changes and results. If the code changes, follow that state.
Still not working?
Reinstallation without improvement calls for reviewing the specific configuration, not a registry cleaner. Provide model, class, version, prior change and resulting code. Plan any system restore with support, backup and review of affected programs.
