"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;

I have a fresh install of WIn7 and running Comodo CIS Anti-Virus that detected this application.
My question too was what does CompatTelRunner do?
My concern is if this is an absolutlety necessary thing or can I shut it down or worse is an infected file?
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.
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

not gonna get Win10, not at least after few years, with that time i think they have patched the issues, mostly i have heard issues with games & mostly with MMO'S, some even mention after upgrade (not sure how it is with clean install), maybe upgrade F something up

i have same question he does, what does CompatTelRunner.exe do, is it win build in malware scanner? or what it is? & why does it run sometimes, it runs mostly on start up? well if its a mal scanner then this answer my last question

Please don't forget that Windows 10 upgrade (providing you are using 7, 8 or 8.1) is only free for 12 months; you MAY be able to download in that perid and install later and if that's your thinking, please check this is ok!

Same here. I have upgraded to Windows 10 Home from Windows 7 weeks ago and my disk is maxed out for 20 minutes on startup every time I start it. So I decided to dig in and found dozens of svchost.exe running, which slowly disappear and dozens of CompatTelRunner.exe start to run. All of them are open to random files throughout my pc. I almost can't even use my pc while this happening because to start something requires disk I/O and there is no bandwidth. Memory isn't full and CPU is 4% or less but I still can't do much during those 20 minutes. Resource Monitor shows the tasks are running in the background, but they are preventing me from doing anything in the "foreground". ANNOYING! When it's done' everything is working just fine. When I did the upgrade, I said to NOT share anything with MS, except errors. So I don't know what it is doing. I thought at first maybe it's some sort of AV, but the name of this exe just doesn't jive with that. If this is about Windows 7 Compatibility, why is it still running after upgrading, and why on every boot up?
