I see from your post that you are getting an error message on your compaq notebook.  Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Did this happen after a recent software update or Windows upgrade?

As you mentioned when you open the webcam on your PC you are getting an error 0xA00F4244 on your PC.

Try the steps recommended below and check if it helps. For detailed instructions, please follow this link: HP PCs - Webcam Troubleshooting (Windows 10, 😎

In Windows, search for and open Device Manager.
Double-click Imaging Devices to expand the list of webcam drivers.
If there is no Imaging devices category listed in Device Manager, stop using these steps and see the section Webcam is not listed in Device Manager in this document.
If more than one webcam driver is listed, right-click the driver and select uninstall for any driver that is not the HP Webcam-101 or Microsoft USB Video Device driver. Once the other drivers have been removed, restart your computer and open your software. If problems persist, continue using these steps.
Right-click the name of the webcam in the Images Devices category (HP Webcam-101 or Microsoft USB Video Device), and select Update Driver Software.
Click Browse the computer to select a specific USB Video Device driver.
Double-click Imaging Devices to expand the list of webcam drivers, right-click the webcam driver, and then select Properties.
Make a note of the existing name of the webcam driver (Example: HP Webcam), as it might change after the update.
On the Webcam Properties window, select Update Driver....
Select to Browse the computer for the desired driver.
Click Let me pick from a list of device drivers on my computer.
Remove the selection from Show compatible hardware.
Select Microsoft in the Manufacturer field, and select USB Video Device in the Model field.
Click Next to install the webcam driver.
Allow the installation of the USB Video Device, and then click Close.
After the device has been updated to USB Video Device in Device Manager, restart your computer and open your software.
If problems persist, install the latest BIOS update from HP and get all the latest Windows updates from Microsoft.

Roll back webcam driver 

Open Device Manager > right-click on the device > select Properties > switch to Driver tab > click on Roll Back Driver button > select Yes on the next window. After that, you need to restart your PC to check whether it is working or not.

Also, install all the latest pending Windows updates as below and check if it helps.

Go to “settings” and click on “update and security”.
Under tab “Windows update”, click on the icon “check for updates”.
Then once you find the pending updates install it and check.
