I have been having a lot of troubles with my Windows Media Player on Windows 7 but I found this cool trick that allows you to reset WMP12 back to it’s default settings. This might be handy if you are encountering any issues of your own.
I have thrown to together a bit of a screen cast to demonstrate the process, it only takes about 30 seconds! Take a look below. (Change quality settings to at least 720p and full screen for better readability).
Simply to go Start > Run (or hold down the Windows Key and press R) and type in the following:
msdt.exe -id WindowsMediaPlayerConfigurationDiagnostic
Press enter and follow the prompts to reset WMP.
I hope this helps someone!
