My HP desktop does not have a F13/webcam shutter key. My webcam does not show up in device manager.

When I turn on my camera I get an error message:  oxA00FH244

In my efforts to resolve my issue I've spent time with HP Virtual Assistant.  The resolution appears to be clicking on F13/webcam shutter key.  My desktop keyboard does not have an F13.  Also, my webcam/camera does not appear in the Device Manager.

Hi@loi78, Welcome to the HP Support Community!

If previously mentioned tips did not help you get rid of the “camera reserved by another app” error, the culprit may be the webcam’s drivers or its settings.  Don’t worry we have a few other steps that should:

To check if any of Windows apps are damaged, run Windows App Troubleshooter. Click on this link and follow the on-screen instructions.

1. Press Ctrl + Shift + Esc or right-click empty space on the toolbar.
2. Open Task Manager and go to the Processes tab.
3. Carefully analyze what programs are currently running in the background of the system.
4. If you found an app that uses Camera, for example, Skype running in the background, click it, and select “End Task.”

To repair damaged system, you have to purchase the licensed version of Reimage.

If the issue persists, 

Perform the reset on the camera

1. Click Windows key + I to open Settings.
2. Select App and Features.
3. Locate Camera and click it.
4. Select Advanced options and then Reset.
5. Reboot the PC.

Perform a clean boot: (no data loss)

1. Click Windows key and type msconfig.
2. Click System Configuration and open Services tab.
3. Mark Hide all Microsoft services box and select Disable all.
4. Open Startup tab and click Open Task Manager.
5. Click on each startup item and select Disable.
6. Close Task Manager and click OK on the System Configuration window.
7. Reboot the system.

If Clean Boot helped you fix the issue, we recommend you to enable apps one by one. After each enabled app, check if the Camera is working.

This way, you will isolate the problematic application.
