"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

    I don't know what GaryNelson007's issue is, but on my laptop running Win 7,  CompatTelRunner.exe  is consuming up to 36% of my CPU time.  IMHO, it's a reasonable bet that when someone notices and asks about what software is doing on a computer, it is likely b.c. it was noticed for making the PC slow.

    On my Desktop Windows 7,  I applied all the described steps - Months ago - and I have not been plagued with that Compattelrunner  Malware since ..  Even after the MS updates to W7 

    For all versions of Windows, start by removing it from the Task Scheduler:

       Start Task Scheduler

       Go to Task Scheduler Library > Microsoft > Windows > Application Experience  

       Disable all three tasks in that folder

       Go to Ask Scheduler Library > Microsoft > Windows > Customer Experience Improvement Program

       Disable all three tasks in that folder

    Then for Windows 10, you need to kill CompatTelRunner.exe from the registry:

       Start Registry Editor (regedit.exe) as Administrator

       Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\TelemetryController

       Rename the entry from TelemetryController to TelemetryControllerX

       Restart your computer.

    It is only on Windows 10 that they reestablish the virus to come back after an update.   The first steps were sufficient for my own windows 7.

    Well this is obvious for most of us but the guy you quoted was dispatched here by MS to do a full denial show, and, as always, try to scapegoat the issue on the users. That's why when it did work that the thread got purposely moved out of sight to a random irrelevant category, and when we complained about it, the trolls added in the title that the thread had been moved to the "appropriate" category.
