Windows 11/10上的摄像头通常默认工作，但如果您的集成摄像头或网络摄像头在^(Webcam)Windows 11/10中无法工作，那么本故障排除指南将帮助您解决问题。为了解决它，我们将查看以下选项：

1. 检查隐私设置。
2. 检查防病毒
3. 更新相机驱动程序。
4. 重新安装相机。
5. 检查设备管理器。

相机在 Windows 11/10 中不工作

就在我们开始之前，请务必检查相机是否已插入系统。它仅适用于您有外接摄像头的情况。

1]检查隐私设置

在Windows 11中，打开Settings > Privacy和功能 >相机^(Camera)并切换开启相机^(Camera)访问。

您还可以在此处控制单个应用程序的访问。

Windows 10在^{(Windows 10)}隐私^(Privacy)方面也有所改进并提供了精细控制。事情是这样的，除非您专门授予许可，否则没有任何东西可以访问您的相机。Windows 10 功能更新禁用了相机访问权限，并且一些应用程序失去了对相机的默认访问权限。

转到设置^(Settings)  > 隐私^(Privacy) > 相机^(Camera)。

打开。 允许应用访问您的相机^{(Allow apps to access your camera)}。

如果该选项显示为灰色，请单击带有选项Change的按钮。它将相机访问的状态更改为打开。

然后打开相机的允许应用程序。

在企业^(Enterprise)或企业^(Corporate)网络中，管理员通过策略禁用摄像头访问。如果您的计算机属于这种情况，请让管理员为您启用设置。发布这个；您可能必须授予对各个应用程序的访问权限，以便他们可以使用相机。

2]检查您的防病毒软件

一些适用于Windows^(Windows)计算机的安全套件会阻止对摄像头的访问。检查可以取消阻止它的软件的设置。

阅读^(Read)：相机丢失或未在设备管理器中显示^{(Camera missing or not showing in Device Manager)}。

3]检查^(Check)过时的网络摄像头驱动程序或过时的网络摄像头

通常，在Windows功能更新后，驱动程序变得不兼容。您可能必须通过软件或使用Windows Update更新相机驱动程序。

Press WIN+X+M打开设备管理器^{(Device Manager)}。

在成像^(Imaging)设备下，找到您的相机列表。

右键单击^{(Right-click)}，然后选择更新驱动程序。

您可以让Windows 10使用更新系统来查找最新的驱动程序。如果您已经下载了它，您可以手动选择它。

您的网络摄像头^(Webcam)可能很旧，并且可能不再适用于Windows 10。找出答案的最佳方法是通过设备管理器^{(Device Manager)}中的相机属性。如果在驱动程序详细信息按钮中，有一个名为stream.sys的文件，那么您需要用新的网络摄像头替换您的网络摄像头。

4]回滚网络摄像头驱动程序

这是另一个常见的场景。更新的驱动程序可能与您的Windows 10 不兼容。修复它的唯一方法是安装旧版本。通常，如果您刚刚更新Windows，您将获得回滚选项，否则您将需要下载旧版本并安装它。

在设备管理器^{(Device Manager)}中打开网络摄像头^(Webcam)属性，然后切换到驱动程序选项卡^{(Driver Tab)}。

单击  回滚驱动程序^{(Roll Back Driver)}，然后选择 是^(Yes)。

回滚完成后，重新启动计算机，然后再次尝试打开相机^(Camera)应用程序。

如果回滚选项不可用，请执行下一步。

5]再次删除并添加网络摄像头

打开Device Manager > Webcam > Properties。切换到驱动程序^(Driver)选项卡，然后单击卸载按钮。

选择^(Choose)卸载驱动软件，然后点击确定。

发布此内容后，选择“设备管理器操作”^{(Device Manager Action)}菜单中可用的扫描硬件更改。^{(Scan for Hardware changes)}

它应该会检测到摄像头，然后您可以让Windows安装驱动程序，或者您可以自己安装驱动程序。

如果您打开设备管理器^{(Device Manager)}并没有看到您的相机列出，请使用扫描硬件更改^{(Scan for hardware changes)}选项。可能是当您插入相机时，它未能检测到，因此它不在系统中。

Lenovo用户可能需要重新安装EasyCamera驱动程序。您可能会在控制面板^{(Control Panel)}中看到它的条目。您可以从他们的网站下载最新的驱动程序设置文件。

Laptop Camera or Webcam not working in Windows 11/10

The camera on Windows 11/10 uѕually works by default, but if your integrated Camera or Webcam does not work in Windows 11/10, thеn this troubleshooting guide will help уoυ resolve the issuе. To rеsolve it, we will look at the following optіons:

1. Check Privacy settings.
2. Check on Antivirus
3. Update Camera driver.
4. Reinstall Camera.
5. Check the Device Manager.

Camera not working in Windows 11/10

Just before we start, always make sure to check if the camera is plugged into the system. It’s applicable only when you have an external camera.

1] Check Privacy settings

In Windows 11, open Settings > Privacy & features > Camera and toggle On Camera access.

You can also control access for individual apps here.

Windows 10 has also improved and offers granular control when it comes to Privacy. Things are such that unless you give permission exclusively, nothing can access your camera. Windows 10 Feature updates disabled camera access and some of the apps have lost the default access to the camera.

Go to Settings  > Privacy > Camera.

Turn on. Allow apps to access your camera.

If the option is grayed out, click on the button with option Change. It will change the status of camera access to on.

Then toggle on the allow apps for the camera.

In Enterprise or Corporate networks, administrators disable camera access through policies. If that’s the case for your computer, ask the admin to enable the settings for you. Post this; you may have to give access to individual apps so they can use the camera.

2] Check your antivirus software

Some security suites for Windows computers, block access of the camera. Check in settings of the software which can unblock it.

3] Check for an outdated webcam driver or outdated webcam

Usually, after a Windows feature update, the drivers become incompatible. You might have to update the camera driver either through the software or using Windows Update.

Press WIN+X+M to open Device Manager.

Under Imaging devices, find your camera listing.

Right-click, and then choose to update driver.

You can let Windows 10 use the update system to find the latest driver. If you have already downloaded it, you can manually select it.

It is possible that your Webcam is very old, and it may not work with Windows 10 anymore. The best way to find out is going through Properties of the camera in the Device Manager. If in the driver details button, there is a file with name stream.sys, then you need to replace your webcam with the new webcam.

4] Rollback webcam driver

Here is another common scenario. An updated driver might not be compatible with your Windows 10. The only way to fix it is by installing an older version. Usually, if you had just updated Windows, you would get a rollback option, else you will need to download an older version and install it.

Open Webcam properties in Device Manager, and switch to Driver Tab.

Click on the  Roll Back Driver, and then choose Yes.

After the rollback is complete, restart your computer, and then try opening the Camera app again.

If the rollback option wasn’t available, follow the next step.

5] Remove & add webcam again

Open Device Manager > Webcam > Properties. Switch to Driver tab, and click on the uninstall button.

Choose to uninstall the driver software, and then click OK.

Post this, select Scan for Hardware changes available with the Device Manager Action menu.

It should detect the camera, and then you can let Windows install the driver, or you can do it yourself.

In case you open the Device Manager and do not see your camera listed, use the Scan for hardware changes option. It is possible that when you plugged in the camera, it failed to detect, and hence it’s not in the system.

Lenovo users may need to reinstall the EasyCamera driver. You may see its entry in the Control Panel. You can download the latest driver setup file from their website.
