Fix Windows 10 Error 0x8007042c

Windows 10 error 0x8007042c usually appears when you try to open Photos, Camera, or other apps that need camera access, and it means Windows can’t start the camera because of a driver, privacy setting, or service problem. The fix is to check your camera privacy settings, restart the Windows Camera Frame Server service, and update or reinstall the camera driver — in that order. Below is a step-by-step guide that resolves the error for most users, plus background on why it happens and what to do if the basic fixes don’t work.

What Causes Error 0x8007042c?

This error is almost always tied to the camera stack in Windows 10. The code itself is a generic Windows error that means “ERROR_NOT_READY” — the device or service isn’t ready to accept a request. When you see it while launching a camera app, one of these is usually the culprit:

• Camera privacy settings — Windows 10 lets you block camera access per-app or entirely. If the toggle is off, the app can’t start the camera and you get this error.
• Camera Frame Server service — This background service manages frames from the camera. If it’s stopped or disabled, no app can access the camera.
• Outdated or corrupted camera driver — A driver that doesn’t match the Windows 10 version or is corrupted will cause the camera to fail.
• Another app using the camera — If the camera is already in use by another program, Windows may return 0x8007042c instead of a clearer message.
• Windows Update issues — A pending or failed update can break the camera stack temporarily.

Step-by-Step Fixes

1. Check Camera Privacy Settings

This is the most common cause and the quickest to rule out.

1. Open Settings (Windows key + I) and go to Privacy.
2. Select Camera from the left sidebar.
3. Make sure Allow apps to access your camera is turned On.
4. Scroll down and ensure the specific app you’re using (e.g., Photos, Camera) is also toggled On.
5. If the toggles are already on, turn them off and on again, then restart the app.

If the toggles are greyed out, you may have a group policy or registry setting that overrides them. In that case, skip to the service and driver fixes below.

2. Restart the Windows Camera Frame Server Service

This service is essential for camera operation. Restarting it clears temporary glitches.

1. Press Windows key + R, type services.msc, and press Enter.
2. Scroll down to Windows Camera Frame Server.
3. Right-click it and select Restart. If it’s not running, right-click and choose Start.
4. Also check Windows Camera Frame Server Monitor (if present) and do the same.
5. Set both services to Automatic by right-clicking, choosing Properties, and changing the Startup type.
6. Close Services and try the camera app again.

3. Update or Reinstall the Camera Driver

A faulty driver is the second most common cause. Updating is easy:

1. Right-click the Start button and select Device Manager.
2. Expand Cameras or Imaging devices.
3. Right-click your camera device and choose Update driver.
4. Select Search automatically for drivers. If Windows finds nothing, try Uninstall device (check “Delete the driver software” if offered) and then restart your PC. Windows will reinstall the driver automatically.

If you have a built-in laptop camera, check the manufacturer’s support site for the latest driver. For external USB cameras, try a different USB port or cable.

4. Run the Windows Store Apps Troubleshooter

Since the error often appears in Store apps, the built-in troubleshooter can help.

1. Go to Settings > Update & Security > Troubleshoot.
2. Select Windows Store Apps and run the troubleshooter.
3. Apply any fixes it suggests and restart.

5. Reset the Camera App

If the problem is specific to the Camera app, resetting it clears its cache and permissions.

1. Go to Settings > Apps > Apps & features.
2. Find Camera, click on it, and select Advanced options.
3. Scroll down and click Reset. Confirm when prompted.
4. Restart your PC and try again.

6. Check for Windows Updates

Microsoft regularly fixes camera bugs in cumulative updates.

1. Go to Settings > Update & Security > Windows Update.
2. Click Check for updates and install any available updates.
3. Restart if prompted.

What to Do If the Error Persists

If you’ve tried all the above and still get 0x8007042c, consider these less common causes:

• Third-party antivirus — Some security software blocks camera access. Temporarily disable it (or its webcam protection) to test.
• Corrupted user profile — Create a new local user account and see if the camera works there. If it does, migrate your files.
• Hardware issue — If the camera doesn’t work in any app or even in Device Manager shows an error (like Code 43), the hardware may be failing. Test with a known-working USB webcam.
• Registry tweaks — Some users have fixed this by adding a DWORD value EnableFrameServer under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation and setting it to 0. This disables the frame server and forces the old camera path. Only try this if you’re comfortable editing the registry, and back it up first.

Common Misconceptions

One frequent myth is that error 0x8007042c means your camera is broken. In most cases, it’s a software issue and can be fixed without replacing hardware. Another misconception is that reinstalling Windows is the only solution — that’s rarely necessary. The error is also not related to the 0x8007042c that appears during Windows Update (that one is a different issue with a different fix).

Frequently Asked Questions

Why does error 0x8007042c appear only in some apps?

Because each app has its own permission toggle. If the Camera app works but Photos doesn’t, check the per-app toggle in Settings > Privacy > Camera. Also, some apps (like older desktop programs) may not support the Windows camera frame server and need the registry fix mentioned above.

Can I fix this without admin rights?

Restarting services and updating drivers requires administrator privileges. If you’re on a work or school PC, contact your IT admin. On a personal PC, make sure your account is an administrator (Settings > Accounts > Your info).

Will this error damage my camera hardware?

No. The error is a software-level failure. It doesn’t cause physical damage. However, if the camera is already failing, the error may appear more frequently, but the error itself won’t worsen the hardware.

How do I know if my camera driver is the problem?

Open Device Manager and look for a yellow exclamation mark next to your camera. If you see one, right-click and select Properties — the error code (like Code 10 or Code 43) will tell you more. If there’s no warning, the driver is likely fine, and the issue is elsewhere.

Does this fix work for Windows 11 too?

Yes, most of these steps apply to Windows 11 as well, though the Settings layout is slightly different. The service names and driver update process are the same. If you’re on Windows 11, the error is rarer but the same fixes apply.
