WMPNETWK.EXE - What is it?

WmpNetwk.exe Service

The WMPNETWK.exe Service belongs to Windows Media Player and is used to share media between different devices (such as PS3, XBox & other PCs) on the same LAN network. WMPNETWK.exe is the service that is used to share your library even if Media Player isn’t open or if your library is empty. If your library isn't empty - it will scan all media files on your hard disk and share them. It can be useful if you need it and rather annoying if you don't.

Disable Media Sharing in Windows Media Player

The easiest way to ensure this process isn't eating up valueble processing power (especially on startup) is to disable sharing from Windows Media Player.

This can be done in 2 ways depending on the version of Windows Media Player you have installed:

To find out which version of Windows Media Player you have installed - Click Start -> All Programs and Open Windows Media Player.

If you are using Windows Media Player 11 when you click Library as shown below - you will have the option 'Media Sharing...'


If you cannot see the option for Media Sharing... as above you can configure Media Sharing via the Options panel then click on the Library tab and click the button Configure Sharing as shown below:

Note that if you are using Windows Media Player 12 the above 'Configure Sharing...' button will be missing from the options control menu - in that case go to the Windows Media Player 12 instructions further down the page.

You will then be given the Media Sharing Settings as shown below:


If the boxes above are already unchecked - check them both and select Apply - then uncheck them and click 'OK' - this re-applies the settings as sometimes they may appear to be switched off while running in the background due to third party applications such as on Sony Vaio Laptops. Once done simply close Windows Media Player and restart your computer. Check the task manager again once you have logged back in to Windows. If it is still running then follow the instructions below for Windows Media Player 12:

Windows Media Player 12 and Disable Services Instructions:

If you are on Windows 7 SP1 you'll most likely be using Windows Media Player 12. In this scenario it is much easier to disable the service from the Services applet.

Open Services from the Control Panel or click Start and type services.msc into the quick search box (Vista & Win7). Find the service 'Windows Media Player Network Sharing Service' in the list as show below:

 Double Left click the highlighted service as shown above and the below menu will be displayed:

 Change the startup type to 'Disabled' as shown above - click Apply and OK - then close the Services Applet and restart your computer. Once booted back up - checking task manager reveals that WMPNETWK.exe is no longer in the list of running applications.
