Can not find camera - Error:0xA00F4244 for HP Pavilion DM4 Notebook PC

[ATM04]

I was in a ZOOM video conference, when my camera stopped working and displayed error: unable to find camera. 

The following error is displayed when you open CAMERA:

Error: We can not find your camera. Error code: 0xA00F4244<NoCamerasAreAttached>

System Model: HP Pavilion DM4 Notebook PC

OS:  Window 10 Home

Device Manager --> Camera --> HP Truevision HD. I ran 'update driver' but was ok. Follow a recommendation, I uninstalled the driver but, now, i can not find it to re-installed it. Camera is not more displayed in Device Manager.

My laptop is up to date with all the Window updates. 

Where I can downloads the driver for HP Truevision HD? or how can I fix this problem?

thanks

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Firstly, perform Windows Update and HP Support Assistant: (do not skip any troubleshooting steps if you feel steps are repeating) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.
