Windows Media Player (WMP)具有媒体共享功能，可让您通过网络将 PC 的媒体库流式传输到其他设备。Wmpnetwk.exe是在后台处理媒体共享服务的进程。
当您第一次在WMP(WMP)上启用媒体共享时，wmpnetwk.exe 会立即开始索引您的媒体库。在此操作期间或将媒体文件流式传输到其他设备时，您可能会注意到CPU 使用率激增。
一旦您的文件被成功编入索引，那应该会立即下降。如果在您不共享媒体文件时 wmpnetwk.exe 继续占用系统资源，请跳至下面的故障排除步骤。但首先，验证 wmpnetwk.exe 文件的安全性和合法性。
Wmpnetwk.exe 可能(Wmpnetwk.exe Could)是病毒(Virus)或恶意软件(Malware)
病毒或木马可以伪装成合法的 wmpnetwk.exe 程序文件来感染您的计算机。因此，在其他任何事情之前，请确认降低您计算机速度的 wmpnetwk.exe 是正版程序文件。
1. 启动任务管理器(Task Manager)，转到详细信息(Details)选项卡，右键单击wmpnetwk.exe，然后选择属性(Properties)。
2. 在常规(General)选项卡中，确保文件位置为C:\Program Files\Window Media Player。
如果文件在此文件夹之外，则很可能是伪装成 wmpnetwk.exe 的恶意程序。通过您的反恶意软件扫描程序运行该文件，或立即将其从您的设备中删除。但是，如果 wmpnetwk.exe 位于适当的位置，则下面的故障排除步骤应该可以解决问题。
1.停止Windows Media Player网络共享服务(Windows Media Player Network Sharing Service)
要解决 wmpnetwk.exe 使用高内存或CPU资源的问题，我们建议终止Windows Media Player 网络共享服务(Windows Media Player Network Sharing Service)。按(Press)Windows 键(Windows key)+ R启动Windows 运行(Windows Run)框。在对话框中键入services并选择(services)OK。
这将启动Windows 服务(Services) 管理器(Manager)。滚动(Scroll)列表中的服务，右键单击“ Windows Media Player 网络共享服务”并选择停止(Stop)。
前往任务管理器(Task Manager)并验证Windows是否停止了该服务。重新启动计算机并在大约 5 到 20 分钟内检查任务管理器。(Task Manager)如果 wmpnetwk.exe 漏洞利用已重新启动或继续在后台运行，请跳至下一个故障排除步骤以更改其启动行为。
2.禁用WMP网络共享服务(WMP Network Sharing Service)的自动启动(Startup)
默认情况下，Windows将在您的 PC 和其他重要服务启动约 2 分钟后自动启动 wmpnetwk.exe 进程。这被称为“延迟启动(Delayed Start)”。
这种启动类型的连锁反应是 wmpnetwk.exe 可能会在后台徘徊 - 无休止地消耗大量内存并导致高CPU使用率 - 即使您不使用Windows Media Player也是如此。
将WMP 网络共享服务(WMP Network Sharing Service)配置为仅在您手动启动时运行应该可以解决问题。打开Windows 服务(Services) 管理器(Manager)，双击“ Windows Media Player 网络共享服务(Windows Media Player Network Sharing Service)”。
选择启动类型(Startup type)下拉按钮，然后从选项中选择手动(Manual)。
然后，选择应用(Apply)，然后选择确定(OK)以保存更改。
3.禁用应用程序的网络共享服务(Network Sharing Service)
将WMP(WMP)网络共享服务配置为手动启动是一种临时修复，尤其是在您不使用Windows Media Player的情况下。禁用该服务是一个更好的选择。
您将无法使用Windows Media Player将内容流式传输或共享到联网设备。但这应该不是问题，因为您不使用该应用程序，对吧？此外(Besides)，您可以随时重新启用该服务。
打开Windows 服务(Services) 管理器(Manager)，双击Windows Media Player 网络共享服务(Windows Media Player Network Sharing Service)，选择启动类型(Startup type)下拉按钮，然后选择禁用(Disabled)。
4.关闭媒体流
如果 wmpnetwk.exe 在索引或流式传输您的媒体文件时遇到问题，它可能会卡在后台。禁用媒体流应该可以解决问题，特别是如果您不打算使用其他设备流媒体文件。
1. 启动Windows Media Player，选择右上角的Stream下拉选项，然后选择(Stream)More streaming options。
2. 或者，打开 Windows 控制面板(open the Windows Control Panel)，选择网络和共享中心(Network and Sharing Center)，然后选择边栏上的媒体流选项(Media streaming options)。
3. 最后，取消选中“此 PC 上的媒体(Media)程序和远程连接”旁边的允许框，然后选择(Allowed)确定(OK)保存更改。
这将禁用本地网络上的媒体流，并停止 wmpnetwk.exe 进程在后台运行。
5. 卸载 Windows 媒体播放器
如果您从计算机中删除 Windows Media Player(Media Player) ，您将永远不必处理 wmpnetwk.exe 威胁。这是解决问题的永久方法——就像从你的花园里拔除杂草一样。
如果上述故障排除步骤均未解决问题，请考虑卸载Windows Media Player 。或者，如果您使用第三方媒体播放(third-party media players)器或服务器，例如VLC、Quicktime、Plex或 Kodi。
1. 启动控制面板(Control Panel)，选择程序和功能(Programs and Features)，然后选择打开或关闭 Windows 功能(Turn Windows features on or off)。
2. 展开Media Feature文件夹，取消选中Windows Media Player，然后选择OK。
3. 在确认提示中选择是(Yes)继续。在此过程中，您可能需要提供您的帐户凭据。

(Did)终止 wmpnetwk.exe 是否解决了高内存或CPU使用率(CPU)问题？还是您必须停止或禁用该过程？让我们知道哪一个成功了。
Fix wmpnetwk.exe High Memory and CPU Usage in Windows
The Windows Media Player (WMP) has a media sharing functionality that allows you to stream your PC’s media library to other devices over a network. Wmpnetwk.exe is the process that handles the media sharing service in the background.
When you enable media sharing on WMP for the first time, wmpnetwk.exe starts indexing your media library immediately. You may notice a spike in CPU usage during this operation, or when streaming media files to other devices.
That should plunge as soon as your files are indexed successfully. If wmpnetwk.exe continues to hog system resources when you aren’t sharing media files, jump to the troubleshooting steps below. But first, verify the safety and legitimacy of the wmpnetwk.exe file.
Wmpnetwk.exe Could Be a Virus or Malware
A virus or trojan can camouflage itself as the legitimate wmpnetwk.exe program file to infect your computer. So before anything else, verify that the wmpnetwk.exe slowing down your computer is the genuine program file.
1. Launch the Task Manager, go to the Details tab, right-click wmpnetwk.exe, and select Properties.
2. In the General tab, ensure the file location reads C:\Program Files\Window Media Player.
If the file is outside this folder, it’s most likely a malicious program camouflaged as wmpnetwk.exe. Run the file through your anti-malware scanner or delete it from your device immediately. However, if wmpnetwk.exe is in the appropriate location, the troubleshooting steps below should fix the problem.
1. Stop the Windows Media Player Network Sharing Service
To resolve the issue with wmpnetwk.exe using high memory or CPU resources, we recommend terminating the Windows Media Player Network Sharing Service. Press the Windows key + R to launch the Windows Run box. Type services in the dialog box and select OK.
That’ll launch the Windows Services Manager. Scroll through the services on the list, right-click “Windows Media Player Network Sharing Service” and select Stop.
Head to the Task Manager and verify that Windows stopped the service. Reboot your computer and check the Task Manager in about 5 – 20 minutes. If the wmpnetwk.exe exploit has relaunched or otherwise continues running in the background, jump to the next troubleshooting step to change its startup behavior.
2. Disable Automatic Startup for the WMP Network Sharing Service
By default, Windows will start the wmpnetwk.exe process automatically about 2 minutes after your PC and other important services start. This is known as a “Delayed Start.”
The ripple effect of this startup type is that wmpnetwk.exe may linger in the background—endlessly consuming high memory and causing high CPU usage—even when you aren’t using the Windows Media Player.
Configuring the WMP Network Sharing Service to only run when you manually start it should resolve the problem. Open the Windows Services Manager and double-click “Windows Media Player Network Sharing Service.”
Select the Startup type drop-down button and select Manual from the options.
Afterward, select Apply and then select OK to save the change.
3. Disable the App’s Network Sharing Service
Configuring the WMP network sharing service to startup manually is a temporary fix, especially if you don’t use Windows Media Player. Disabling the service is a much better alternative.
You won’t be able to stream or share content to networked devices using Windows Media Player. But that shouldn’t be a problem since you don’t use the app, right? Besides, you can always re-enable the service any time in the future.
Open the Windows Services Manager, double-click Windows Media Player Network Sharing Service, select the Startup type drop-down button, and select Disabled.
4. Turn Off Media Streaming
If wmpnetwk.exe encounters a problem while indexing or streaming your media files, it could get stuck in the background. Disabling media streaming should solve the problem, especially if you don’t plan to stream your media files with other devices.
1. Launch the Windows Media Player, select the Stream drop-down option at the top-right corner, and select More streaming options.
2. Alternatively, open the Windows Control Panel, select Network and Sharing Center, and select Media streaming options on the sidebar.
3. Finally, uncheck the Allowed box next to “Media programs on this PC and remote connections” and select OK to save the change.
That’ll disable media streaming on your local network and stop the wmpnetwk.exe process from running in the background.
5. Uninstall Windows Media Player
You’ll never have to deal with the wmpnetwk.exe menace if you remove Windows Media Player from your computer. It’s a permanent solution to the problem—like unrooting a weed from your garden.
Consider uninstalling Windows Media Player in the unlikely event that none of the troubleshooting steps above fixed the problem. Or, if you use third-party media players or servers like VLC, Quicktime, Plex, or Kodi.
1. Launch the Control Panel, select Programs and Features, and select Turn Windows features on or off.
2. Expand the Media Feature folder, uncheck Windows Media Player, and select OK.
3. Select Yes on the confirmation prompt to proceed. You may need to provide your account credentials during the process.
