I fixed the problem of my wmp12 situation, What i did was first,
At first i tried the default file association thing and that didn't work, so first i went to he control panel and turned off the media features on the programs and features
and then i downloaded the CCleaner from the link below:
I went to CCleaner - Optimization and Cleaning - Free Download
to get CCleaner for my computer.
then I went the ccleaner that installed and analyzed and cleaner the system, the multimedia programs, advanced system options, windows explorer, and some of the ther things that nedded cleaning. then I went to the registry on the cleaner and checked for any issues and cleaned those up to. then i restarted my computer. then i went to program files and deleted the windows media player program folder. I also made sure i deleted all of the files that had anything to do with windows media player 11 on it and dleleted those from my computer.
then, i went to the registry editor andwent to find and typed the following: wmp, wmp11, wmploc,wmpband, and any other .egs that had wmp and searched throughout the entire registry and deleted and/or modifyed all of the .reg files with wmp on them. then after double checking to make sure i deleted anything to with wmp11, i then went to the control panel and turned the media features back on on the programs and features section o the control panel and then rebooted my computer.
