How to Troubleshoot Windows Media Player
Although the Windows Media Player or WMP is far from the most modern media-playing application available (its last significant update dates to 2009), many users still prefer it for music or movies. However, even a default Windows application can break, just like third-party ones. Users with recurring problems with accessing the WMP, even if they don't need it, should resolve them as part of maintaining a stable Windows environment.
A non-launching WMP is one of the more common issues. First, users should determine that the application isn't present in memory, even if there's no visible UI interface or window. This problem is a frequent symptom of an unexpected software crash. Open the Task Manager application and look for the Windows Media Player entry. If necessary, right-click it and choose 'End task.' Then re-launch WMP as usual. While in the Task Manager, users also may experiment with closing other programs and services if any of them conflict with WMP.
If Windows Media Player isn't present, users can install it. They also can uninstall and reinstall it as a workaround for other issues. Since it's a part of Windows, the procedure is slightly different from removing or adding a third-party program. Type 'Apps & features' in the taskbar and click the result. Then choose 'Optional features.' If WMP isn't present, the 'Add a feature' button will let you select it. Otherwise, click the program's entry, uninstall it, and then add it.
Tidying up a PC's memory and program list can solve many software problems, but not all of them. Application-specific freezes, or incidents where the program no longer responds, can be outdated software, reading corrupted files and other problems. Fortunately, since Windows installs the latest version of WMP by default, users have no responsibility for maintaining updates.
In cases of file corruption, users should re-acquire (usually by re-downloading) the file. If necessary, use a download-resuming program to guarantee that the file isn't incomplete. Malware experts also remind users not to take files' names too literally. Some threats will disguise themselves as movies, music, and similar media, even though they are EXE or executable files. Always confirm the format of a file before opening it.
Users also might want to delegate the task to Windows, which provides specialized troubleshooting tools. Type 'Troubleshoot other problems' in the taskbar and click the result. Examples of potentially-useful troubleshooting categories include 'Windows Store Apps,' 'Video Playback' and 'Playing Audio.' Windows will attempt to detect the problem and suggest solutions.
A corrupt or bloated WMP library is another possible source of freezes. To manually 'clean' it, type '%LOCALAPPDATA%\Microsoft\Media Player' in the taskbar. Then delete the files in the opened folder (the WMP's application data for the user profile). The WMP should rebuild the library upon launching.
Most users never need to go to these extremes to resolve a fundamental problem with a media-playing application. Still, knowing the available options can help define a troubleshooting environment and put one's mind at ease whenever a program like the WMP exhibits unexpected and unwanted behavior.
