想象一下^(Imagine)，您正在使用笔记本电脑，突然发现您的网络摄像头灯在闪烁。您不想找出并知道哪个应用程序正在使用您的网络摄像头^{(which app is using your webcam)}吗？它可能是像Skype这样的合法软件，也可能是恶意软件——因此，进一步调查这一点很重要，尤其是如果这种情况不止一次发生！Windows 11/10/8/7中找出哪个应用程序正在使用您的网络摄像头，以及如何选择可以使用或访问您的摄像头的应用程序。

如何找出正在使用我的网络摄像头的应用程序？

要找出Windows 11中哪个应用程序正在使用您的网络摄像头，您需要借助Windows 设置^{(Windows Settings)}。为此，按 Win+I 打开Windows 设置^{(Windows Settings)}并切换到 隐私和安全 ^{(Privacy & security )}选项卡。在这里您可以找到一个名为“让应用程序访问您的相机”^{(Let apps access your camera)}的标题 。在此标题下，您可以找到所有具有相机访问权限的应用程序。如果您想阻止某个应用使用您的相机，您需要切换相应的按钮将其关闭。

哪个应用正在使用网络摄像头

在 Windows 10 计算机上，从WinX 菜单^{(WinX Menu)}中打开设备管理器^{(Device Manager)}并识别系统的网络摄像头设备。您将不得不展开 成像设备^{(Imaging device)}。在我的笔记本电脑上，我看到一个条目Integrated Webcam。双击它以打开其属性^(Properties)框。现在在Details选项卡下，查看Physical Device Object name的^{(Physical Device Object name)}属性^(Property)。就我而言，它是 \Device\0000004a。

右键单击它并选择复制。

现在从Microsoft Sysinternals下载Process Explorer。这个免费的便携式工具会告诉您哪个程序打开了哪个文件、进程或目录，以及有关哪些句柄和DLL^(DLLs)进程因此而打开或加载的信息。

工具打开后，按Ctrl+F打开其搜索^(Search)框，将复制的文本粘贴到此处，然后单击搜索^(Search)。

该工具将搜索您所有正在运行的进程并查看其中哪些进程正在使用此句柄，并在此处列出该进程。

一旦您确定了正在使用您的网络摄像头的进程，您可以右键单击它并选择Kill Process。如果您不希望该工具使用网络摄像头。

如果您怀疑恶意软件，请运行防病毒软件扫描。

提示^(TIP)：使用 Who Stalks My Cam 软件防止网络摄像头黑客攻击。

^(Choose)Windows 11/10选择哪些应用^(Apps)可以使用我的网络摄像头

要在Windows 11^{(Windows 11)}中选择可以使用网络摄像头的应用程序，请执行以下步骤：

1. 按 Win+I 打开Windows 设置。
2. 转到左侧 的隐私和安全 ^{(Privacy & security )}设置页面。
3. 找出 让应用程序访问您的相机的 ^{(Let apps access your camera )}标题。
4. 切换相应的按钮以打开或关闭相机访问。

但是，如果您使用的是Windows 10，请按照以下步骤操作：

使用Windows 10 设置^(Settings)，您可以管理和选择可以访问您的网络摄像头并使用您的摄像头的应用程序。^(Apps)从WinX 菜单^{(WinX Menu)}中，打开设置 > 隐私> Camera。在这里，您将看到可以访问您的网络摄像头的应用程序列表。

在这里，您可以简单地将让应用程序使用我的相机^{(Let apps use my camera)}开关切换到关闭^(Off)位置以拒绝网络摄像头访问所有应用程序，或者您可以单独将开关切换到关闭^(Off)或打开位置以停止或允许每个应用程序访问您的相机。通过这种方式，您将能够管理哪些应用程序可以使用您的网络摄像头。

如今，使用远程访问技术 (RAT)，^{(Remote Access Technology (RAT), )}黑客可以破坏您的系统并使用您自己的网络摄像头监视您、监控您的活动，甚至记录您的行为！Â因此，如果您是一个从不使用网络摄像头并且害怕被监视或监视的人，那么您可能需要禁用网络摄像头^{(disable the webcam)}。当然，如果需要，您可以随时再次启用它。

为什么我的相机被另一个应用程序使用？

如果您在Windows 11^{(Windows 11)}或Windows 10上打开摄像头访问权限，则任何应用程序都可以使用集成或外部网络摄像头而无需进一步许可。但是，您可以阻止任何特定应用程序使用计算机上的相机。为此，您需要仔细执行上述步骤。

How to find out which app is using the webcam in Windows 11/10

Imagine yоu are working оn your laptop and you suddenly find that your web camera light is flickering. Wouldn’t уou like to find out and know which app is using your webcam? It could be a legit software like Skype, or it could be malware – and so it is important that you investigate this further, especially if this happens more than once! In this post, we will see how to find out which app is using your webcam in Windows 11/10/8/7 & how you can choose the apps that can use or access your camera.

How do I find out what application is using my webcam?

To find out which application is using your webcam in Windows 11, you need to take the help of Windows Settings. For that, press Win+I to open Windows Settings and switch to the Privacy & security tab. Here you can find a heading called Let apps access your camera. Under this heading, you can find all the app that has camera access. If you want to prevent an app from using your camera, you need to toggle the corresponding button to turn it off.

Which app is using the web camera

On your Windows 10 computer, from the WinX Menu, open Device Manager and identify the web camera device of your system. You will have to expand Imaging devices. On my laptop, under  I see an entry Integrated Webcam. Double-click on it to open its Properties box. Now under the Details tab, see the Property for Physical Device Object name. In my case, it is \Device\0000004a.

Right-click on it and select Copy.

Now download Process Explorer from Microsoft Sysinternals. This free portable tool tells you which program has a which file, process or directory open along with information about which handles and DLLs processes have opened or loaded because of it.

Once the tool is open, press Ctrl+F to open its Search box, and paste the copied text here and click on Search.

The tool will search all your running processes and see which of them is using this handle, and list the process here.

Once you have identified the process that is using your webcam, you may right-click on it and select Kill Process. if you do not want that tool to use the webcam.

If you suspect malware, run your antivirus software scan.

Choose which Apps can use my web camera in Windows 11/10

To choose apps that can use your web camera in Windows 11, follow these steps:

1. Press Win+I to open Windows Settings.
2. Go to Privacy & security settings page on the left side.
3. Find out the Let apps access your camera heading.
4. Toggle the corresponding button to turn on or off camera access.

However, if you are using Windows 10, follow these steps:

Using Windows 10 Settings, you can manage and choose the Apps that can have access to your webcam and use your camera. From the WinX Menu, open Setting > privacy > Camera. Here you will see the list of apps that have access to your webcam.

Here you may simply toggle the Let apps use my camera switch to the Off position to deny webcam access to all apps or you may individually toggle the switch to the Off or On position to stop or give access to your camera for each app. In this way, you will be able to manage which apps can use your web camera.

These days, using Remote Access Technology (RAT), hackers can compromise your system and watch you, monitor your activities, and even record your actions, using your own webcam!  So, if you are one, who never uses the webcam and who fears being watched or monitored, using it, you may want to disable the webcam. You can of course always enable it again anytime in the future, should the need arise.

Why is my camera being used by another application?

If you turn on the camera access on Windows 11 or Windows 10, any app can use the integrated or external webcam without further permission. However, you can block any particular app from using the camera on your computer. For that, you need to follow the aforementioned steps minutely.
