About Windows 8 using WMP to play music when wudfhost run CPU and hard drive problem resolution

When Windows 8 uses Windows Media Player to play music, there is actually a situation in which WMP and what the name looks like are very high on the CPU, this run is high depending on the number of files in the SD card you insert or the number of files that are moving the hard disk, if there are many files, This runs to get the system to die quickly.

Just like this:

Reason:
WMP commands the WPD system service to scan external Removable storage, which is used to update the Media Library.
System services to access the mobile device, constantly scanning the files to traverse the mobile device, so the IO and CPU use is very high, resulting in system card, read access slow.

Solve:

Open the service, find the portable Device Enumerator service, you can see it by default is manual, drop-down to prohibit, OK, restart the computer OK.
