In case you are wondering why Windows Media Player runs in 32 bit mode when you have a 64 bit Windows 7, and how to run the 64 bit version, read on. It seems that by default Microsoft decided on running the 32 bit version, perhaps for codec compatibility. However, the 64 bit version is already included. To use this instead (the quick and easy way) do the following 10 second fix:

1. Unpin the WMP icon from the taskbar (assuming that’s where you started it from)
2. Open C:\Program Files\Windows Media Player\wmplayer.exe (Notice it’s not the C:\Program Files (x86) folder).
3. Just pin that version instead and you are set.

Here’s the result:

My Digital Life blog has posted a rather complex solution that modifies the registry. However, this does will not work if you still have the 32 bit version pinned to the taskbar and you use it from there. Much simpler than running all those registry hacks is to run your 64 bit version and associate all audio and video files with it.

I find that the performance is at least moderately better, especially when loading my immense music library. WMP 32 bit seems to freeze up for at least 5-10 seconds, whereas x64 just takes a second or two. The 64 bit version seems to take up about 7-8MB more RAM, but not that I care now that I have 4 GB to spare.
