在工作中，查看哪个进程占用过多cpu或内存不是那么简单的事，可能很多进程都依附于system或是svchost.exe。
那么，如何进一步查看呢？
download and run it, then select the system process, right-click and select properties:
switch to the threads tab (ignore the dialog box that mentions symbols):
this will show which file is using the excessive cpu usage, from which you can then attempt to diagnose it.
