Windows Media Player is one of the favorites for watching videos or listening to music on PC. Some of the reasons include the fact that it comes pre-installed by Windows OS, it supports most media player formats and users can enjoy several functions, such as creating playlists.
How to fix the problem
Sometimes, Windows Media Player does not work or users cannot open it or play MP4 or DvDs/CDs. Other malfunctioning systems include no response when clicking the icon of the player or a blue circle which keeps circling but nothing happens.
Bellow, there are a couple of suggestions which could fix the problem
The first suggestion is to run built-in WMP Troubleshooters. To do so, users need to run Windows Media Player Settings, Windows Media Player and Windows Media Player DVD Troubleshooters. Some of these built-ins might give you a clue about what problem could be.
A second suggestion is to re-register the DLL files
To perform this task, it is necessary to open Command Prompt with a simple Win+X and to run several commands: regsvr32 vbscript.dll, regsvr32 jscript.dll, regsvr32 wmp.dll. After each command, the user has to press enter and once he/she finishes, the PC needs to be restarted.
Delete or uninstall and re-install Windows Media Player
Sometimes it can be necessary to delete the Media Library without opening it. Another option would be to uninstall it from Control Panel, then Programs, Features and choosing the option Turn Windows features ON or OFF.
Other users find it helpful to use Fix WMP Utility for windows. This is a free app which re-registers all Windows Media DLL files, which are required for a good functioning of the player.
Windows Media Player was released for the first time in 1991 with Windows 3.0.
