From looking at this the following steps are needed:

Win 7 sdk installed 
Then C:\Program Files\Microsoft SDKs\Windows\v7.1\Redist\Windows Performance Toolkit\wpt_x86.msi
File downloaded from http://hg.mozilla.org/mozilla-central/raw-file/360ab7771e27/toolkit/components/startup/mozprofilerprobe.mof
install the file "mofcomp mozprofilerprobe.mof" 

The installation directory seems to need to be the task user home directory. 

grenade: I am working on getting a solution working for now with generiworker 8, but ultimately could the file installation be added into the test preflight script the same way the firewall exception were? (currently on PTO I will need info him once he is back)

another thought is we could run xperf on the VMs as it doesn't require hardware or timing- it just measures IO operations for file access, this could simplify a few things.

jmaher: Do you know if the profile location is important or does it just need to be available in the repo available to the WMI server?

this is starting to get out of my knowledge domain.  I believe with you mofcomp it is added to the OS proper, not the end user- then it is accessible via global wmi provider.

I have verified this works on a VM and runs xperf:

so taskcluster + OCC works fine in the land of windows 7, and I would argue we don't need to run this on hardware.

Sounds good. 

Oddly enough I am not seeing the file install in the configuration, so I am wondering where it is coming from.
