Fix Camera Freezes in Microsoft Teams

If your camera freezes in Microsoft Teams during a call, the fix is usually a combination of closing bandwidth-hogging apps, updating your graphics or camera drivers, and disabling hardware acceleration in Teams. Below is a step-by-step guide that resolves the issue for most users, followed by deeper context on why it happens and how to prevent it.

Why Your Camera Freezes in Teams

Teams is a resource-heavy application. It uses your webcam, encodes video, and renders the interface simultaneously. A freeze—where your video becomes a still image for others or where the preview freezes for you—typically comes from one of these causes:

Insufficient CPU or GPU resources: Other apps (browsers, games, screen recorders) are competing for the same hardware.
Outdated or corrupt camera drivers: Windows updates or third-party software can break the driver that Teams relies on.
Hardware acceleration conflict: Teams’ built-in GPU acceleration can cause rendering glitches on some graphics cards.
Network instability: A weak or fluctuating connection can cause Teams to drop video frames, which appears as a freeze.
Background apps using the camera: Another app (like a browser tab or a security camera viewer) may have exclusive access to the webcam.

Step-by-Step Fixes

Work through these in order. Most users find the fix in the first three steps.

Close other apps that use the camera or heavy resources. Check your system tray for apps like Zoom, Skype, or any camera utility. Close unnecessary browser tabs, especially those with video or heavy animations.
Update your camera and graphics drivers. Open Device Manager (right-click the Start button), expand “Cameras” and “Display adapters,” right-click each device, and select “Update driver.” Choose “Search automatically.” Restart your PC after updating.
Disable hardware acceleration in Teams. In Teams, click your profile picture at the top right, select Settings > General, and uncheck “Disable GPU hardware acceleration” (note: this checkbox is labeled as “Disable” but you are enabling the disable—so check it to turn off acceleration). Restart Teams.
Clear Teams cache. Close Teams completely (right-click the Teams icon in the system tray and choose “Quit”). Press Win + R, type %appdata%\Microsoft\Teams, and delete the contents of the Cache, Code Cache, and GPUCache folders. Restart Teams.
Check your network. Run a speed test. For video calls, you need at least 1.2 Mbps upload/download. If your connection is unstable, use a wired Ethernet connection or move closer to your router.
Set Teams to high performance in Windows. Go to Settings > System > Display > Graphics, select Teams, click Options, and choose High performance (dedicated GPU if available).

What to Do If the Fix Fails

If you’ve done all the above and the camera still freezes, try these additional steps:

Repair Teams: Go to Settings > Apps > Apps & features, find Microsoft Teams, click Modify, and choose Repair.
Reinstall Teams: Uninstall Teams completely, then download the latest version from the official Microsoft site.
Use the web version: In a browser, go to teams.microsoft.com and join the meeting there. If the web version works, the problem is with the desktop app.
Test with another app: Open the built-in Camera app in Windows. If it also freezes, the issue is with your camera hardware or driver, not Teams.

Common Misconception: “It’s a Bandwidth Issue”

Many users assume that a frozen camera means their internet is too slow. While a poor connection can cause video to freeze, it usually affects the incoming video or the entire call. If your outgoing video freezes but you can still hear others clearly, the problem is almost always local—either your hardware, drivers, or Teams settings. Bandwidth issues typically cause choppy audio, not a perfectly frozen video frame.

Preventing Future Freezes

Once you’ve fixed the immediate problem, take these steps to avoid it happening again:

Keep drivers updated: Set Windows Update to automatically install driver updates, or check your camera manufacturer’s website periodically.
Limit background apps: Close unnecessary programs before a meeting. Use Task Manager (Ctrl+Shift+Esc) to see which apps are using high CPU or GPU.
Use a wired connection: If you’re on Wi-Fi, consider an Ethernet cable for stable, consistent bandwidth.
Restart Teams regularly: Teams can accumulate memory leaks. Quit and reopen it at least once a day.

Frequently Asked Questions

Why does my camera freeze only in Teams, not in other apps?

This usually points to a Teams-specific setting or conflict. The most common cause is hardware acceleration. Disabling it (as described in step 3) resolves the issue for many users. If that doesn’t help, try clearing the Teams cache or repairing the app.

Can a VPN cause Teams camera freezes?

Yes. A VPN can introduce latency and packet loss, which can cause video to freeze. If you use a VPN, try disconnecting it during a meeting or switching to a different server. Some corporate VPNs also block certain ports that Teams uses for video, so check with your IT department.

Does using a virtual background cause camera freezes?

Virtual backgrounds require additional GPU processing. If your graphics card is older or doesn’t support hardware acceleration, applying a virtual background can cause the camera to freeze. Try turning off virtual backgrounds in Teams settings (Background effects > None) to see if that helps.

How do I know if my camera driver is outdated?

Open Device Manager, expand “Cameras,” right-click your camera, select “Properties,” and go to the “Driver” tab. The date and version are listed there. Compare it with the latest version on your camera manufacturer’s website. If you’re unsure, run Windows Update and install any optional driver updates.

Will reinstalling Teams delete my chat history?

No. Your chats and files are stored in the cloud. Reinstalling the app only removes local cache files. You’ll need to sign in again, but all your conversations and shared files will still be there.

Is there a way to prioritize Teams in Windows for better performance?

Yes. Go to Settings > System > Display > Graphics, find Teams, click Options, and set it to High performance. This tells Windows to use your dedicated GPU (if you have one) for Teams, which can reduce freezes.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
