Check your antivirus software

In your antivirus app, look for settings related to blocking access or permission to use your webcam. For help, visit your antivirus software company’s website.

Check for an outdated webcam driver

Select the Start button, type Device Manager, and then select Device Manager from the search results.

Find your webcam under Imaging devices or Sound, video and game controllers.

Press and hold (or right-click) the name of your webcam, and then select Properties.

Select the Driver tab, select the Driver Details button, and look for a file name that includes stream.sys. If it’s there, your webcam was designed before Windows 7 and you'll have to replace it with a newer webcam.

If you don't find a file name that includes stream.sys, try rolling back your webcam driver.

Roll back your webcam driver

In Device Manager, press and hold (or right-click) your webcam, and then select Properties.

Select the Driver tab, select Roll Back Driver, and then choose Yes. (Note that some drivers don’t provide a rollback option.)

After the rollback is complete, restart your PC, and then try opening the Camera app again.

If rolling back didn’t work or isn’t available, uninstall your webcam driver and scan for hardware changes. 

Uninstall your webcam driver and scan for hardware changes

In Device Manager, press and hold (or right-click) your webcam, and then select Properties.

Select the Driver tab, select Uninstall > Delete the driver software for this device, and then select OK.

In Device Manager, on the Action menu, select Scan for hardware changes. Wait for it to scan and reinstall updated drivers, restart your PC, and then try opening the Camera app again.

If your webcam still doesn’t work, try looking for help on the webcam manufacturer’s website.

Hi Sake. I'm Greg, an installation specialist and 9 year Windows MVP, here to help you.

Did you enable the Privacy setting to allow apps to use your webcam?

Try the Hardware & Devices troubleshooter at Settings > Update & Security > Troubleshoot.

Try Updating the webcam driver from the HP Drivers update page for your exact model here: http://support.hp.com/us-en/drivers. Install it even if it's the same or newer than the one in Device Manager reached by right clicking the Start button.

Also compare all other drivers including Chipset, display, sound, etc to make sure you have the latest on the PC maker's Support Downloads web page.

Right click Start button to access Device Manager, locate Webcam device (if necessary from View tab Show Hidden Devices), on Driver tab see if Roll Back is available, if not try Update Driver, first automatically, then Browse, then Let Me Pick to try all previously installed Drivers.

If these fail try to Uninstall the Driver, restart PC to reinstall.

If this was caused by Windows Updates then you can check which were installed at Settings>Update & Security>Windows Update under Installed Updates, then uninstall them from the link there, and hide with the Hide Updates tool downloaded from here: http://download.microsoft.com/download/f/2/2/f2...

You can also use System Restore to get before the problem began, then check for Updates with the Hide Update tool and hide them: http://home.bt.com/tech-gadgets/computing/how-t...

Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files. Then continue with the other steps to go over your install most thoroughly.

If nothing else helps what I'd nstall Media Creation Tool from this link and choose Upgrade This PC Now: http://windows.microsoft.com/en-us/windows-10/m...

This is the most stable way to change to the newer version and because it reinstalls WIndows while keeping your files and programs in place, fixes most problems. It also brings all Windows Updates to date.

If there are any hurdles during install then these steps can overcome them: http://answers.microsoft.com/en-us/windows/wiki...

You can monitor the Windows 10 Blog here to get notified of the exact date for release of Spring Creators Version 1803 which is soon: https://blogs.windows.com/windowsexperience/#ut...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
