When Windows 8 uses Windows Media player to play music. In fact there is one such situation, WMP and some what name looks very big cock process run CPU very high, this run very high depending on the number of files that you inserted in the SD card or the number of files on the removable hard disk. Assuming there are so many files, this will run to get the system up and running.
Just like this:
Reason:
WMP commands the WPD system service to scan external Removable storage, which is used to update the Media Library.
The system service goes to the mobile device, constantly scanning the files that traverse the mobile device, so the IO and CPU usage is very high, resulting in the system card. Read access is slow.
Solve:
Open the service. Locate the Portable Device enumerator Service and be able to see it by default is manual and the dropdown is disabled instead. OK, restart the computer OK.
