"I disagree. I think you should get Windows 10 now"

I agree with Nekked Runner .

Not a good response as I too had the same basic question;

  1. I have a fresh install of WIn7 and running Comodo CIS Anti-Virus that detected this application.
  2. My question too was what does CompatTelRunner do?
  3. My concern is if this is an absolutlety necessary thing or can I shut it down or worse is an infected file?
  4. After repeated questioning it was finally admitted that it is a program that while desireable for those interested in upgrading would not be needed by some people as myself.
  5. From what I gather reading between lines of the respondant is that it is neither necessary nor will there be any negative impact to me by not allowing to to run except that maybe my computer and OS run better without it using resources.

So my solution was to tell Comodo CIS to just block and terminate this application every time it attempts to run. 

I did not have time yet to go though checking the services running to see if it can just be disabled there or if I need to search the registry manually but before going that far I think I may let Revo Unistaller have a go at it.

Hope this helps you

    Taking up a ton of disk space. What does it do?

    I had the same problem. 

    Using procexp.exe, I found that the offending process was started from a scheduled task, namely, Microsoft Compatibility Appraiser, which is found in Computer Manager under Task Scheduler\Microsoft\Windows\Application Experience\ProgramDataUpdater. There are three tasks in that folder.

    The description of the task says "Collects program telemetry information if opted-in to the Microsoft Customer Experience Improvement Program.", so I suppose we can simply opt-out from the telemetry program and this should not run anymore. I believe that is in Settings->Privacy->Feedback. But Windows Insider machines probably require this to be on.

    I suppose we can disable these tasks in the Task Scheduler.

    It alleviated the problem in my machines as far as I can tell.
