如果您无法在 Windows PC 上使用Skype并且您看到错误消息Your Webcam is being used by another application，那么这里有可能帮助您解决问题的解决方案。

此错误不允许您将网络摄像头用于Skype，因此无法进行视频会议。内部/集成和外部网络摄像头都可能发生这种情况。

Skype 说，您的网络摄像头正被另一个应用程序使用

这个问题没有任何具体的原因。一些可能的原因如下：

1. 影响系统的病毒^(Virus)或恶意软件。
2. ^(Old)Skype for Desktop软件的旧版本或损坏版本。
3.  相机的驱动程序可能已损坏。
4. Skype应用程序可能无法访问网络摄像头。
5. 防火墙^(Firewall)、防病毒软件或某些网络摄像头保护可能会限制摄像头和Skype之间的链接。
6. 使用相机的其他一些应用程序可能尚未关闭，可能正在后台运行。

考虑到各种可能性，您可以按以下顺序对问题进行故障排除：

1. 运行防病毒扫描
2. 使用相机杀死进程
3. 禁用防火墙
4. 更新相机驱动程序
5. 打开“允许应用程序访问相机”。
6. 重置相机应用
7. 禁用网络摄像头保护
8. 重新安装 Skype for Desktop。

1]运行防病毒扫描^{(1] Run an anti-virus scan)}

运行完整的系统反恶意软件扫描，从而消除此类原因的可能性。

2]使用相机杀死进程^{(2] Kill the process using the camera)}

打开任务管理器^{(Task Manager)}（按CTRL+ALT+DEL打开安全^(Security) 选项^(Options)窗口并从列表中选择任务管理器^{(Task Manager)}）。

检查除Skype之外的任何使用摄像头的程序是否仍处于活动状态并正在运行。

如果是，您可能会考虑终止该进程并重新启动系统。

3]禁用防火墙^{(3] Disable Firewall)}

暂时禁用系统上的任何防病毒或防火墙^{(Firewall )}。这是为了确保这些都不会干扰网络摄像头的功能。隔离问题后，您可以打开电源。

4]更新相机驱动程序^{(4] Update the camera drivers)}

Press Win + R打开运行^(Run)窗口。键入命令devmgmt.msc并按Enter打开设备管理器^{(Device Manager)}。

展开摄像头^(Camera)驱动程序列表并右键单击网络摄像头的驱动程序并选择更新^(Update)驱动程序。

重新启动系统。

5]打开“允许应用程序访问相机”。^{(5] Switch ON “Allow apps to access the camera.”)}

单击^(Click)“开始^(Start)”按钮，然后选择类似齿轮的符号以打开“设置”^(Settings)菜单。转到隐私^(Privacy)。

在左侧的应用^(App)权限列表中，选择相机^(Camera)。打开允许应用程序访问您的相机^{(Allow apps to access your camera)}的切换开关。

此外，请查看选择哪些应用程序可以访问您的相机^{(Choose which apps can access your camera)}下的列表。对于Skype^(Skype)，该开关应为 ON 。

请记住^(Remember)，桌面版^(Desktop)Skype的显示与系统上预装的Skype应用不同。

6]重置相机应用程序^{(6] Reset the Camera app)}

即使我们错过了取消相机与正在使用它的程序的链接，重置应用程序^{(resetting the app)}也可以完成这项工作。

单击^(Click)开始Start > Settings > Apps > Apps和功能。

滚动^(Scroll)列表以找到相机^(Camera)应用程序。单击^(Click)它以展开选项并选择高级^(Advanced)选项。

滚动^(Scroll)选项并找到Reset。单击^(Click)重置^(Reset)并允许其处理。

作业完成后重新启动系统。

7]禁用网络摄像头保护^{(7] Disable webcam protection)}

某些^(Certain)安全软件带有网络摄像头保护。它可能是您的通用防病毒软件的一个选项，也可能是专用软件。如果您意识到这一点，暂时禁用网络摄像头保护以隔离问题可能会有所帮助。

8]重新安装桌面版Skype^{(8] Re-install Skype for Desktop)}

如果一切都失败了，你可以考虑卸载并重新安装Skype for Desktop。就像^(Just)任何其他应用程序一样，Skype可以从控制面板的^{(Control Panel)}程序^(Programs)和功能^(Features)菜单中卸载。您可以从Skype^(Skype)的官方网站重新安装该应用程序。

All the best!

Skype - Your webcam is being used by another application

If you are unable to usе Skype on your Windows PC and you see an error message Your Webcam is being used by another application, then here are the potential resolutions that will help you fix the problem.

This error doesn’t allow you to use the webcam for Skype thus making video conferencing impossible. It can occur for both internal/integrated and external webcams.

Your webcam is being used by another application, says Skype

This issue doesn’t have anyone specific cause. A few of the probable causes are as follows:

1. Virus or malware affecting the system.
2. Old or corrupt version of the Skype for Desktop software.
3.  The drivers for the camera could be corrupt.
4. The Skype application might not have access to the webcam.
5. A Firewall, anti-virus or some webcam protection might be restricting the link between the camera and Skype.
6. Some other application using the camera might not have been closed and could be running in the background.

Considering the various possibilities, you could troubleshoot the problem sequentially as follows:

1. Run an anti-virus scan
2. Kill the process using the camera
3. Disable Firewall
4. Update the camera drivers
5. Switch ON “Allow apps to access the camera.”
6. Reset the camera app
7. Disable webcam protection
8. Re-install Skype for Desktop.

1] Run an anti-virus scan

Run a full system anti-malware scan, thus eliminating the possibility of such a cause.

2] Kill the process using the camera

Open the Task Manager (press CTRL+ALT+DEL to open the Security Options window and select Task Manager from the list).

Check if any program other than Skype which uses the camera is still active and running.

If yes, you might consider killing the process and restarting the system.

3] Disable Firewall

Temporarily disable any anti-virus or Firewall on the system. This is to make sure that neither of those interferes with the functioning of the webcam. You may switch then ON after isolating the issue.

4] Update the camera drivers

Press Win + R to open the Run window. Type the command devmgmt.msc and press Enter to open the Device Manager.

Expand the list of Camera drivers and right-click on your webcam’s driver and select Update driver.

Restart the system.

5] Switch ON “Allow apps to access the camera.”

Click on the Start button and then select the gear-like symbol to open the Settings menu. Go to Privacy.

In the list for App permissions on the left-hand side, select Camera. Turn the toggle switch ON for Allow apps to access your camera.

Also, check the list under Choose which apps can access your camera. The switch should be ON for Skype.

Remember that Skype for Desktop shows different from the pre-installed Skype app on your system.

6] Reset the Camera app

Even if we missed unlinking the camera to a program which was using it, resetting the app would do the job.

Click on Start > Settings > Apps > Apps & features.

Scroll through the list to locate the Camera app. Click on it to expand the options and select Advanced options.

Scroll through the options and find Reset. Click on Reset and allow it to process.

Restart the system once the job is done.

7] Disable webcam protection

Certain security software comes with webcam protection. It might be an option is your general anti-virus software, or it could be a dedicated software. If you are aware of the same, disabling webcam protection temporarily to isolate the issue could be helpful.

8] Re-install Skype for Desktop

If everything else failed, you could consider uninstalling and reinstalling Skype for Desktop. Just like any other application, Skype can be uninstalled from the Programs and Features menu in the Control Panel. You can re-install the application from Skype’s official website.

All the best!
