Windows Media Player Causes CPU to run at 100%

Ok, so I'm currently on my computer, wondering why its running slow, when i look at my CPU usage, its on 100% for both cores, the culprit is WMP... Is their any reason on why windows media player slams so much usage on my CPU, it goes from 5% max each core up to minimum 87% on core 1 & 2?

Did you check any of the Enhancements in the Properties of the Playback device. Enhancements can eat CPU power.

Everything on WMP is set to its default settings, nothing has been changed except for the equalizer.

How about the ' Playback devices " - the ones accessed from the speaker icon in the task tray. Those that are in the device properties > Enhancement tab.

And the WMP equalizer can play an act on you too.

The playback devices are shown in the picture and the sound scheme is set to Windows Default.

Double click on " Speakers " and check in the Enhancement tab.

Nothing has been changed on that and all tick boxes within the selection screen are all unticked.

Check in Reource Monitor > CPU tab which processes are actually monopolizing the CPU.
