I've found that on a very fast new machine CPU usage runs between 0-8% normally, but then with wmplayer on it hovers between 8-18%. The problem is particularly to my new machine with Windows 7, and doesn't occur on my old Vista machine.

I believe it's possibly because every time I open wmplayer it tries to load up every media file on my computer into the startup screen. Assuming I want to keep using wmplayer (and since I've got a lot of playlists set up there, I do), how can I fix this problem?

Try to ending the process, this should end all spikes. Try using Vlc Media Player.

Alternatively, set wmp to not index all media files. To do this follow the information below.

Open Media Player > Click Organize > Select Options Under the Library tab, Uncheck Retrieve additional information from the internet Close Media Player and reopen to see of the process is any faster.

The real way is go into Media Player.  From the menu -> File -> Manage libraries -> select each library (music, video, pictures, recorded tv [if you have]) and check the paths that it is managing and make sure it is not too close to the root of the C: drive.  For example, it should be something like c:\users\Jim\Music and c:\users\Public\Music BUT NOT c:\users as they will cause the whole directory tree to be re-indexed over and over (when you surf the web or change any files in your profile). If you have multiple users who login to the computer, you may need to repeat the process for each user if all users have added managed foldTers which are actively changing on a regular basis.

See this site for the original post.

Thanks for the advice. I have a couple of questions. 1. why does it need to reindex every time I open the program? On my Vista machine it does not do this, and I don't have these CPU usage problems even though the machine is much older. 2. How can I set wmplayer to not index all media files? –  SwanWhisperer Oct 28 '12 at 3:41
I updated my answer. –  wizlog Oct 28 '12 at 3:51
Thanks. Unchecking Retrieve additional information from the internet fixed the problem for me. None of the managed paths were close to c:\users, so I didn't change anything there. –  SwanWhisperer Oct 28 '12 at 4:09


I had a problem with WMV files using 100% of a core, to fix it I turned off Options/Performance "Turn on Direct-X video Acceleration for WMV files".
