The wmpnscfg.exe file is a part of the Windows Media Player Network Sharing Service Configuration application. This application is used by Windows Media Player to allow several users to access and save various types of media files in a device. The wmpnscfg.exe file is available in Windows Media Player 11. This file was developed by Microsoft Corporation and is bundled with its Windows Operating System.
The main function of the wmpnscfg.exe file is to notify the user if a new media device has been found in the network. Upon its execution, the wmpnscfg.exe file waits for signals from the network’s system that a device has been attached to one of the work stations. The file will display a pop-up on the user’s system tray. This pop-up contains information about the availability of the device found. When the user clicks on the pop-up on the system tray, the wmpnscfg.exe file will load Windows Media Player. This program will then ask the user whether or not he wishes to allow sharing with the device.
The wmpnscfg.exe file is commonly found in C:\Program Files\Windows Media Player\. However, this may vary depending on the path which the user specified during installation. The start up entry for this file can be automatically started from a Run, RunOnce, RunServicesOnce, or RunServices entry in the registry.
The user must not terminate the wmpnscfg.exe file while the network sharing service of Windows Media Player is running. If the user is certain that he will not use the features of wmpnscfg.exe, he may unload it by going to the media sharing module of Windows Media Player and unchecking the option for the said file.
