Collecting Data Using Xperf for High CPU utilization of a process

We can investigate the high CPU utilization for a process using xperf tool.

Please download it from here and choose following installation option while installing it.


It would install windows performance tool kit in c:\program files and you will find a folder by this name in program files. Please copy all the  files in this  folder , create a folder in C drive with name xperf(you can give it any name ) and paste all the files copied from performance tool kit folder( this step is to ease the process of data capture).

Open an elevated command prompt and run following command to enable the key for xperf

REG ADD "HKLM\System\CurrentControlSet\Control\Session Manager\Memory Management" -v DisablePagingExecutive -d 0x1 -t REG_DWORD -f

Reboot the server to activate this key.

    This would really come in handy if you would walk it step by step. I downloaded the tools but I cant accomplish anything because I dont know much and you dont really walk me throught it.
