Wmpnetwk.exe is an application file of Windows Media Player that’s used when you share Windows media libraries with other networked media players. Left unchecked, Wmpnetwk.exe and its related application, Wmpnscfg.exe, can rapidly shoot up memory usage and consume 100% of CPU. In this tutorial, we discuss the role of Wmpnetwk.exe in Windows and some of the ways to solve the high memory problem when it bursts out of control.

What Is Wmpnetwk.exe in Task Manager?

Wmpnetwk.exe’s main purpose is to share Windows Media Player libraries with other networked players and media devices using Universal Plug and Play. If you aren’t using your Windows PC to stream with other players, it’s best to stop the WMPNetworkSvc from the Task Manager Services tab. You can restart it later if you want.

Wmpnetwk.exe will always show in the Task Manager under the Services tab as WMPNetworkSvc, which stands for “Windows Media Player Networking Service”. Under the same name, it can also be found under the Processes tab. Whether or not you’re running Windows Media Player, the application’s overall impact on CPU, memory, disk, and power usage should be very minimal.

Causes for Wmpnetwk.exe High CPU Usage

The following are the main reasons you may be facing this issue on a Windows device.

  • Latest Windows versions make WMPNetworkSvc run automatically: The problem has been around since the Windows 7 era. In the past, Windows disabled WMPNetworkSvc from automatically running. However, in the latest versions of Windows, you may find it enabled automatically. Most choose to ignore this even though the process silently consumes a lot of memory in the background.
  • The process is never ending: even if you stop the WMPNetworkSvc process from the Task Manager, it has a tendency to restart itself continuously. Sometimes the process springs back even after you’ve disabled it.
  • Media library indexing accumulation over time: if you have enabled media streaming once and forgot to switch it off, the Windows Media Player will start indexing your media library with newer video and audio files. Even when you use other media players like VLC or Groove, the Wmpnetwk.exe process keeps consuming resources in the background.
  • Duplicate and conflicting files: sometimes you have other programs and applications similarly named as Wmpnetwke.exe or Wmpnscfg.exe. This can cause a conflict with the original Windows Media Player file. A system cleanup works best in these cases.
  • Dependent services: some services depend on other services, system drivers or load order groups. For Wmpnetwk.exe, the dependent services include MsQuic and Windows Search. You may find the application has restarted if you use them.
  • Malware named after Wmpnetwk.exe: malware authors can name their spyware and viruses anything, and Wmpnetwk.exe is a common target. However, the Windows Defender-based security has a built-in mechanism to reject these vectors.

Solutions for Wmpnetwk.exe High CPU Usage

While the Wmpnetwk.exe and Wmpnscfg.exe application files cannot be removed entirely from your PC, their impact can be minimized. From terminating the executable files to turning off media streaming and uninstalling Windows Media Player, one of these methods is going to ease the problems of high memory spikes.

1. Disable Wmpnetwk.exe Service

Wmpnetwk.exe is not an essential service and disabling it won’t affect the operation of the system. It’s recommended to prevent the application from running automatically.

2. Use System File Checker and DISM to Repair Corrupt Files

If there are corrupt or duplicate Wmpnetwk.exe files in the system folders, you can get rid of them through command-line utilities, such as System File Checker and DISM.exe. To perform these actions, you need an elevated Command Prompt access.

Once it has finished repairing, it may leave behind a CBS.log text file under the Logs subfolder of Windows. You can check it to determine whether there are any Wmpnetwk.exe issues that were repaired.

5. Check Windows Media Player Folder for Older File Versions

If you have any older Wmpnetwk.exe or Wmpnscfg.exe file versions lurking around in the Windows Media Player folder, it can cause conflicts and high memory spikes due to the Windows Media Player service. Here’s how to resolve this.

  1. The Windows Media Player folder can be located easily from Program Files or Program Files (x86) folder in your system. Find a file called “Wmpnetwk.exe”.
  2. Look for duplicate instances of the file. Keep “View” on for “Hidden files and folders.”
