This post teaches you how to download and update webcam or camera driver on Windows 10 so that your built-in or external webcam/camera can well communicate with your computer. Some tips to fix webcam not working on Windows 10 are also included. More computer solutions and utilities, please visit MiniTool Software official website.
Fix 4. Reinstall or roll back the webcam or camera driver on Windows 10. You can press Windows + X and select Device Manager. Expand Imaging devices, Cameras or Sound, video and game controllers. Right-click your webcam and select Properties. Click Driver tab and select Uninstall device to remove the webcam driver on Windows 10. Restart your computer and it will automatically install the webcam driver. If you want to roll back the webcam driver to an old version, you can click Roll Back Driver to install the old version of the webcam driver.
When your camera isn't working in Windows 11, it might be missing drivers after a recent update. It's also possible that your antivirus program is blocking the camera, your privacy settings don't allow camera access for some apps, or there's a problem with the app you want to use.
If there are no updates for your camera, try to select Advanced options > Optional updates, and look for any driver updates for your camera. Allow available updates to install, then restart your device when it's ready.
Some laptops and portable devices have a physical switch or button that turns the camera on or off. When it's turned off, your device may not recognize that there's a camera installed, or it may cause your camera to show an image of a camera with a slash through it. If your laptop has a switch or button, make sure it's in the on position before using your camera.
If you're having problems with an app that you did not install from Microsoft Store, make sure that Let desktop apps access your camera is turned on. You can't turn off camera access for individual desktop apps. Internet browsers, like Microsoft Edge, and many video conferencing apps, like Microsoft Teams, are desktop apps that require this setting to be turned on.
Most available USB webcams are UVC (standard USB Video Class) compatible cameras. They will work with the UVC driver that is included in Windows (the in-box UVC driver). If your webcam is not working correctly, swapping to the in-box UVC driver may resolve the issue. Please follow the steps below to change drivers (admin rights are required).

Check for updates. Select Start , then select Settings > Update & Security > Windows Update > Check for updates. If you see the option to View optional updates, select it to see if there are updates available for your camera. Allow available updates to install, then restart your device when it's ready.

After allowing access to the camera, go to Choose which Microsoft Store apps can access your camera and turn on camera access for the apps you want. Only apps installed from the Microsoft Store will show in this list.
If you installed the app from the internet, a disc, a USB drive, or your IT administrator installed the app for you, it might not be a Microsoft Store app. To check, go to Allow desktop apps to access your camera and make sure it's turned on. Internet browsers (like Microsoft Edge) and many video conferencing apps (like Microsoft Teams) are desktop apps that require this setting to be turned on.
Step 3. Right-click on this, then press Uninstall device. This option should uninstall the current camera driver on your Windows registry. Once finished, you will not be able to use your device for the moment.
The steps below can be used to manually uninstall and reinstall the camera drivers for USB 3.0, USB 2.0 and FireWire cameras. To update or re-install the driver, without first uninstalling, skip ahead to step 5.
UWP device apps let device manufacturers apply custom settings and special effects on the camera's video stream with a camera driver MFT (media foundation transform). This topic introduces driver MFTs and uses the Driver MFT sample to show how to create one. To learn more about UWP device apps in general, see Meet UWP device apps.
This section describes the Media Foundation Transform (MFT) that you create to apply effects to the media capture stream coming from the camera. This is how you provide transforms for color effects, scheme modes, and face-tracking effects that really distinguish your camera from others. This MFT, known as the driver MFT, is first applied to the connected video stream coming from the camera driver when a UWP app begins video capture. When that app invokes the Camera options UI, Windows automatically provides access to any interfaces the driver MFT implements for controlling its custom effects.
The UWP device app for a camera runs in a different process than the Microsoft Store app that invokes it from the CameraCaptureUI API. For the Microsoft Store device app to control a driver MFT, a specific sequence of events across different process spaces must occur.
The driver MFT is instantiated per stream. For each stream the camera supports, an instance of the MFT is instantiated and connected to it. The driver MFT is expected to have a single input stream and a single output stream. The driver MFT may be either a synchronous MFT or an asynchronous MFT.
In this example, the MFT_CONNECTED_STREAM_ATTRIBUTE in the driver MFT's attribute store is set to point to the device source stream's attribute store. See Hardware Handshake Sequence for further details on how communication between the camera and the MFT is set up.
You'll need to include header files for the IInspectable and IMFTransform methods that the driver MFT must implement. For a list of header files to include, see stdafx.h in the SampleMFT0 directory of the UWP device app for camera sample.
A driver MFT that's intended for use from a camera's UWP device app must implement the methods of IInspectable so that the Microsoft Store device app can access a pointer to the driver MFT when launched. Your driver MFT should implement the methods of IInspectable as follows:
Each interface your driver MFT implements should implement and derive from IUnknown, in order to be correctly marshaled to the camera's UWP device app. The following is an example .idl file for a driver MFT that demonstrates this.
The Wrapper subproject in the UWP device app for camera sample provides an example of how to expose your driver MFT to the Windows Runtime so that you can use it from a UWP device app implemented in C# or JavaScript. It is designed to work together with the Driver MFT sample. See the Driver MFT sample page for a step-by-step guide to installing, running, and testing the samples.
Your camera installer registers the driver MFT by calling regsvr32 on your driver MFT DLL, or by providing a driver manifest (.man) file for the DLL that the installer uses for registration.
Set the CameraPostProcessingPluginCLSID value in the registry key for your camera. Your INF file should specify the CLSID of the Driver MFT in the device class registry key for the device, by setting the CameraPostProcessingPluginCLSID value to the CLSID GUID of the driver MFT class. The following is an example from an INF file entry that populates the registry keys for a camera:
After the first installation of the app, if the user downloads an updated version of the app, then the updates are automatically integrated into the camera capture experience. However, updates are not downloaded automatically. The user must download additional app updates from the Microsoft Store, because the app is automatically installed only on first connect. The main page of your UWP device app can provide notifications that updates are available and provide links to download updates.
UWP device apps for internal cameras are eligible for Automatic installation from the Microsoft Store, but it is recommended that they be pre-installed for the most seamless user experience. There are additional steps required to support internal cameras and associate a UWP device app with them. For more info, see Identifying the location of internal cameras.
For both internal and external cameras, you need to create a device metadata package. When you submit your camera's UWP device app to the Microsoft Store (or preinstall it using the OPK, in the case of internal cameras), in addition to the app itself, you'll need to provide metadata containing the following:
Although Windows 10 can automatically configure most cameras, it does not mean they will continue operating with issues indefinitely. Sometimes, peripherals can stop working for many reasons. For instance, it could be due to a problem with the driver, recent system updates, privacy settings blocking access to the camera, or hardware-related issues.
