How to Completely Uninstall and Reinstall Webcam Drivers in Windows

A standard device uninstall in Device Manager removes the device entry itself, but by default leaves the underlying driver files in place in Windows' driver store — meaning a simple reconnect or restart often just reinstalls the exact same, potentially corrupted driver files right back, without actually resolving whatever was wrong in the first place.

The specific checkbox for "Attempt to remove the driver for this device," shown during the uninstall process, is what actually deletes those underlying driver files from the driver store — this is the genuinely important step that distinguishes a surface-level uninstall from a real, clean reinstallation that gives Windows a completely fresh start.

Step 1: Open Device Manager

— right-click the Start button and select it.

Step 2: Expand Cameras or Imaging devices

And find your webcam.

Step 3: Right-click it and select "Uninstall device."

Step 4: Check the box for "Attempt to remove the driver for this device"

In the confirmation dialog before clicking Uninstall.

Step 5: Restart your computer completely.

Windows automatically detects the camera fresh on boot and reinstalls an appropriate driver from scratch. ↑ Confirm the camera works with the widget above once your PC restarts.

If Windows' automatic reinstall doesn't fully restore functionality, downloading the manufacturer's official driver directly from their website, rather than relying on Windows' generic driver, is the appropriate next step for a camera that specifically needs vendor software beyond basic UVC capture.

How do I reset the Windows Camera app itself?

Go to Settings → Apps → Installed apps, find Camera, open its three-dot menu, and choose Advanced options → Reset. This clears the built-in Camera app’s own cache and settings without uninstalling it, which can fix a stuck, frozen, or permanently black preview even when the underlying device and driver are both working correctly. It only resets that one app — not your camera driver, and not other applications that use the camera.

Could my antivirus be silently blocking my camera?

Many third-party security suites — Bitdefender, Kaspersky, Norton, and ESET among others — include their own webcam-protection feature that runs independently of Windows’ own privacy settings. That means Windows can show camera access as fully permitted while the antivirus software blocks it anyway, at a layer Windows has no visibility into. Check the antivirus program’s own settings, usually under a Privacy, Webcam Protection, or similarly named section, and confirm your browser or conferencing app is on its allow-list.

How do I re-enable my camera in Device Manager if it's disabled?

Right-click the Start button → Device Manager, expand Cameras or Imaging devices, and look for a greyed-out icon or a small down-arrow badge. Right-click that entry and choose Enable device. This is a different action from updating a driver — a disabled device won’t respond to any other fix until it’s explicitly re-enabled here first, so it’s worth checking before assuming the problem is a driver or a permission.

Is Windows' own camera privacy toggle blocking access, separately from anything else?

Windows keeps a system-level camera permission at Settings → Privacy & security → Camera, completely separate from Device Manager, the Camera app, and any antivirus software. This one screen has a master Camera access switch plus a per-app list beneath it — both need to be on. It’s worth checking directly, since a camera can show as fully enabled and working in Device Manager while this toggle silently blocks every app from reaching it.
