A freezing webcam can make a meeting feel like a badly paused movie. Before replacing the camera or reinstalling Windows, try a few targeted checks: test the preview in the Windows Camera app, close other camera apps, and, for an external webcam, change its USB connection.

These steps apply to Windows 10 and Windows 11 and take about 15 minutes. You’ll need the affected webcam and, if it’s external, another suitable USB port. Test after each change so you can tell what helped.

A user checks a USB webcam on a laptop, where camera access is enabled and a caller waves on screen. 1. Test the webcam in the Camera app​

  1. Save your work and close video meetings, recording software, and browser tabs that might be using the camera.
  2. Open Start, type Camera, and select the Camera app.
  3. If prompted, allow camera access. If your PC has more than one camera, use the app’s camera-switch control to select the one you want to test.
  4. Watch the preview and move your hand in front of the lens for a minute or two. If the freeze usually takes longer, leave the preview running for roughly that long.

Success looks like: the preview continues moving without sticking on one frame. If it works in Camera but freezes in a meeting app, the camera may be functional and the problem may be specific to that app, its settings, or the call connection. Microsoft recommends the Camera app as a way to distinguish an app-specific problem from a broader camera problem.

If the preview is black rather than frozen, check the lens cover and any physical camera switch or keyboard button before continuing.

2. Check for another app using the camera​

A video-call app, browser tab, or recording tool may still be running in the background. Depending on the camera and software, another app’s access can interfere with your test.

  1. Close any meetings and recording sessions, then quit the apps involved. Also close browser tabs that may be using the camera.
  2. Check the notification area near the clock for apps that are still running, and quit them if appropriate.
  3. Open Task Manager by right-clicking the taskbar and selecting Task Manager. If you recognize an app that may be using the camera and it hasn’t closed, select it and choose End task. Save its work first; don’t end processes you don’t recognize.
  4. Reopen Camera and repeat the preview test.

If the preview now works, open the app you actually want to use and test it again. Check that it has selected the correct webcam. For a browser-based meeting, also check that the browser and website have permission to use the camera. Microsoft notes that another browser tab can be enough to keep a camera busy in some situations.

If Camera works but the call still freezes: the meeting app, its camera selection, effects, permissions, or the network connection are worth investigating. A stable local preview is useful evidence, but it doesn’t prove which part of the call is at fault.

3. Try another USB port​

Skip this step if the affected camera is built into your laptop.

  1. Close the Camera app and any other software using the webcam.
  2. Unplug the webcam and connect it securely to another compatible USB port on the PC. If it was connected through a hub or dock, try a direct connection to the PC.
  3. Open Camera and repeat the preview test.

If the camera becomes stable on the new connection, the original port, hub, dock, cable, or connection may be involved. That is a clue—not proof that the port itself is defective. You can compare the original connection again later to see whether the problem returns. Microsoft also recommends trying a different USB port for an external camera.

4. Disconnect other USB devices and retest​

For an external webcam, reduce the number of variables:

  1. Close the Camera app.
  2. Safely eject any external storage before unplugging it. Disconnect unnecessary USB devices, particularly other cameras or capture devices. Leave the keyboard, mouse, and anything essential connected.
  3. Keep the webcam connected directly to the PC if possible.
  4. Open Camera and repeat the same preview test.
  5. If it is stable, reconnect the other devices one at a time, retesting after each connection.

If freezing returns after a particular device or hub is reconnected, that combination deserves a closer look. It may point to a connection or shared-resource issue, though this test alone cannot identify the exact cause.

If the camera still freezes​

Work through these checks next:

  • Check camera permissions. In Windows 11, open Settings > Privacy & security > Camera. In Windows 10, open Settings > Privacy > Camera. Enable device and app access as needed; for desktop meeting apps and browsers, also check the desktop-app access setting. If a control is unavailable on a work PC, ask your administrator.
  • Restart the PC. Use Start > Power > Restart, then test in Camera again.
  • Check for updates. Look for Windows and optional camera driver updates, then restart if prompted. On Windows 10, Windows Update is under Settings > Update & Security; on Windows 11, it’s under Settings > Windows Update.
  • Try the webcam on another computer, if it is external. A similar failure there makes the camera or its cable more suspect; a stable test suggests looking further at the original PC.
  • Try Basic camera mode on Windows 11, version 24H2 or later. Microsoft says this troubleshooting mode turns off hardware acceleration and, where possible, manufacturer camera plug-ins. Go to Settings > Bluetooth & devices > Cameras, select the camera, and choose Edit under Advanced camera options, if available. Turn on Basic camera and retest. Windows Studio Effects won’t work while this mode is enabled.

Finally, note the results: whether Camera itself froze, which port you used, and whether disconnecting a device changed anything. That short list gives your IT team or the webcam manufacturer a much better starting point than “it froze during my meeting.”
