Windows 7: I need Help reinstalling wmp12 that was preinstalled in windows 7

What if i dont have a windows 7 installation disc

Try this. I dont know whether it'll work.

Uninstall wmp11 (you have already), delete the WMP folder in Program Files, delete the registry key you mentioned in your post, then reboot.

Now, check wmp amd wmc boxes in "Turn windows features on/off" (turn them on), reboot.

Now see whether wmp12 works.

Maybe you can also try CCleaner to wipe off the remaining wmp11 reg entries as well as folders/ files after uninstalling it.

I need Help reinstalling wmp12 that was preinstalled in windows 7

When I go to my music files after uninstall wmp 11 on it. all of my music files would say, assocfile.wmp11.mp3 or assocfile.wmp11.file on the music files, is there anything i can do to fix this?

See if restoring the default file association for mp3 in this tutorial fixes that.

Default File Type Associations - Restore

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.

Sounds like Bill2's advice did the trick, Thanks for posting back your results.
