Itunes causes 96% cpu usage after using command

[smirk24]

Okay so i applied a command to my system then also changed win32priorityseperation to hex 26 my computer feels a whole lot faster thank God well the command i used is wmic process where name="explorer.exe" CALL setpriority "128"

And when im listening to music using itunes my cpu usage is at 96% according to task manager.

Is this something i should worry about?

Thanks in advance
