Camera in Use by Another Application: How to Fix It in Windows

The short answer

The message means the app you just opened asked Windows for the camera and could not get it. Usually another program, such as a video-call app, the Camera app, a browser tab or a background utility, already has the camera open, and many camera setups serve only one program at a time. The fix is to find and close whatever is holding the camera, then reopen the app you actually want to use.

The wording can be misleading. The same error can appear when no other window is visibly open. A process may still be running in the background, a driver may have stopped responding, or something may be blocking access to the camera. If closing apps does not help, work through the later steps in order.

Step 1: Close the apps most likely to be using the camera

Start with programs that commonly open the camera and keep running after you close their window:

• Video-call and meeting apps, including ones that start automatically when you sign in
• The Windows Camera app
• Browser tabs that had a call, meeting or camera test open
• Streaming or recording software, especially tools that create a virtual camera
• Camera utilities from the computer or webcam manufacturer

Many call apps keep running in the notification area at the right end of the taskbar after you close the main window. Open the hidden-icons arrow there, right-click any call or camera app, and choose its quit or exit option. Closing the window alone is not always enough.

Step 2: Check which apps used the camera recently

Windows can show which apps have accessed the camera. In Windows 11, go to Settings, then Privacy & security, then Camera. Look for the list of apps and any recent-activity information. In Windows 10 the camera privacy settings are under Settings, then Privacy, then Camera. Exact labels vary between Windows versions and updates, so look for the closest match.

If an app is shown as currently using the camera, or used it recently when you did not expect it to, close that app first. If you do not recognize it, turn off its camera permission on the same page.

Step 3: End leftover processes in Task Manager

Press Ctrl+Shift+Esc to open Task Manager. On the Processes tab, look for call, meeting, streaming or camera-related programs that are still running. Select one and choose End task. Only end programs you recognize. Ending unfamiliar system processes can cause other problems.

If you cannot tell what is holding the camera, restart the computer. A restart closes every program at once. Then open only the app you need before anything else starts using the camera.

Step 4: Confirm the app is allowed to use the camera

Sometimes the real problem is a blocked permission, even though the error mentions another application. On the same Camera privacy page in Settings, check these items:

• Camera access for the device is turned on
• Apps are allowed to access the camera
• The specific app you want to use is switched on, if it appears in the list
• Desktop apps are allowed to access the camera, if you are using a traditional installed program rather than a Store app

If you use the camera through a website, the browser has its own camera permission. Check the camera setting for that site in the browser's site permissions. Make sure no other tab or browser window has the camera open.

Step 5: Rule out hardware switches and security software

Some laptops and webcams have a physical privacy shutter, a camera switch on the side, or a keyboard key that turns the camera off. Depending on the device, these can produce a black image or an access error. Check that the shutter is open and the camera key is not set to off.

Some security suites include a webcam-protection feature that blocks apps they do not trust. If yours has one, check whether it is blocking the app you want to use. Whether your security software has such a feature depends on the product; check its settings rather than assuming.

Step 6: Reset the camera connection and driver

If no app seems to be using the camera but the error persists, the camera driver may be stuck. A driver is the software that lets Windows talk to the camera hardware. Try these in order, testing after each one:

• For an external USB webcam: unplug it, wait a moment, and plug it into a different USB port, preferably directly on the computer rather than through a hub.
• Open Device Manager by right-clicking the Start button, expand Cameras or Imaging devices, right-click your camera, choose Disable device, then right-click it again and choose Enable device.
• In Device Manager, right-click the camera and choose Uninstall device, then restart the computer so Windows reinstalls it.
• Check Windows Update, including optional driver updates, and the computer or webcam maker's support software for a newer camera driver.

If the problem started right after a driver update, the driver's Properties window in Device Manager may offer a Roll Back Driver option on the Driver tab. This option is available only when a previous driver is stored on the system.

How to check that it is fixed

Confirm the result in stages, because each stage tells you something different:

• Access: open the Windows Camera app by itself. If it opens without an error, Windows can hand the camera to an app.
• Capture: confirm you see a live, moving image, not a black or frozen frame. An app can gain access and still receive no usable picture, which points to a shutter, privacy switch or driver issue.
• Your actual app: close the Camera app, then open the call or recording app you need and select the correct camera in its video settings, especially if you have more than one camera or a virtual camera installed.
• Call quality: if the image is clear in a test but poor during a call, that is a separate issue, usually lighting, bandwidth or app settings, not the in-use error.

Limits of this guide

No device-specific evidence was available for this guide. Menu names, privacy options and camera-sharing behavior can differ between Windows 10 and Windows 11 builds and between device makers, and newer Windows releases may handle multiple apps differently. If none of the steps help, the camera hardware may be faulty. Testing an external webcam, or testing the same camera on another computer, can help confirm whether the hardware is at fault. After that, the computer or webcam maker's support is the next step.
