Windows 10: How to intentionally corrupt performance counter for testing purpose

Hi,

I want to intentionally corrupt performance counters(Perfdisk,PerfNet & PerfOS) to verify whether it is rebuild properly or not by our application since it depends on these performance counters. Currently I corrupt it by running 'lodctr /r' command and while it is executing I power down the system and boot it and verify. I see it is getting corrupted.

I tried another method by deleting the 'Library' parameter in "HKLM\System\CurrentControlSet\Services\Perdisk\Performance". I'm not sure whether windows understands this state as corrupted or not.

And is there any other method to corrupt Performance Counters?


Thanks!!

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Unselectable and Disappearing Counters in Performance Monitor / Perfmon.exe

Computer: Dell Latitude 7480

Program: Perfmon.exe (32 bit and 64 bit)

OS: Windows 7, Widows 10

I am trying to add counters for USB in Performance Monitor. I want to do something similar to this:

• How to Troubleshoot USB Problems : How to Identify USB Problems Using Performance Monitor, How to Examine USB Hubs - Windows Vista - allcomputers.us
• How to Identify USB Problems Using Performance Monitor - Windows 7 Tutorial

In the screen-shot, I use % total bandwidth used for Interrupt as an example, but this applies to any counter with a grayed out/ unselectable
<All instances> instance.

When add >> is selected it seems to add the counter, but once you select
OK, the counter disappears. It does not show up in Perfmon and does not show up in
Properties -> Data. It's almost as if I never added it.

I have quite a few internal and external USB hubs, and USB devices on this computer, so I'm not sure why there are no instances to select. Maybe that is a clue? Is there something I have to enable first?

There isn't good documentation describing what the grayed out <All instances> means, can anyone please explain? Even if it is alone in the list,
<All instances> is sometimes gray and sometimes not. For me,
Thread counters only have <All instances> but it is not grayed out, while the
USB counters have <All instances> but are grayed out. Also not sure what is different between a blank
Instances of selected object: list and a grayed out out Instances of selected object:
list is.

Additionally, can anyone help me monitor/ enable the USB counters?

Thank you in advance!
