Compatibility Telemetry Service

[dudeman509]

W10 Home x64, so I don't have Group Policy editor.

I have tried just about every Registry tweak and disabling every service I've seen in Internet Articles related to this crap, and STILL every time I start up my desktop, the Telemetry Compatibility service starts up and thrashes my E:\ drive, which is a spinning disk, and slows any access on the darn thing to a crawl. Kill the service from task manager, and it stops instantly and disk usage falls to 0.

My 2 W10 laptops (one Pro, one Home) don't seem to have issues with this, as they both have SSDs and never seem to be thrashed by that, even though I never even tried to disable it on them.

Is there any way to PERMANENTLY disable this stupid service on startup???

After a google search, I found the following two articles:
https://www.neowin.net/forum/topic/1261368-microsoft-compatibility-telemetry-service/
and
http://windowsitpro.com/windows-10/how-turn-telemetry-windows-7-8-and-windows-10

As I haven't tried them, they may or may not work. Use at your own risk.

Yep, tried disabling them as shown in the 2nd. They still show as disabled and not started, yet the stupid thing is still running.

Haven't tried deleting them altogether. Might give that a shot, but Windows will probably just re-create them.

Hope this helps! As before, no guarantees!

It appears deleting the service in its entirety (via the 1st article) killed it permanently.

At least until Windows updates and re-installs it or something...

Thanks for the help

You are welcome!
Who knows what M$ will put in an update?

 

[dudeman509]

Nope, it's back after a couple restart cycles, thrashing my disk and CPU cycles.

I would completely reinstall Windows if I thought this would go away, but I don't think it will.

I went a step further and ran:
echo “” > C:\ProgramData\Microsoft\Diagnosis\ETLLogs\AutoLogger\AutoLogger-Diagtrack-Listener.etl

which said it was in use, so rebooted in Safe Mode and knocked that out. So far, it's not running on this restart cycle.

I'm going to run an Ad-Aware scan as well as a Spybot scan, though since I can kill the process, I think it's just Windows.

 

[dudeman509]

As expected, nothing showed up in scans...where as if this weren't part of Windows, it absolutely would be considered malware.

Well, we'll see if it stays gone more than a day or two with this attempt.

When it came back, did you find the compattelrunner.exe program?

Every single step/method in there has been done at this point.

 

[dudeman509]

Yay! It's back.

Both services are disabled and the DiagTrack Listener doesn't appear to be in use this time.

However, Windows keeps deleting that registry key addition at random - nothing will be there and that service will be back up and running and my hard disk thrashing away after an unspecified number of reboots.

 

[dudeman509]

Update:

Done all the usual steps in those things (registry hack, deleting/stopping services), etc. Keeps coming back.

There appears to be a task in task scheduler under Microsoft->Windows->Application Experience to do with compatibility. Deleted that and I THINK it's gone for good now.

One can only hope! Do you remember what that task was?

Well, hopefully Windows update won't start it up again!

 

[dudeman509]

Nope, figured it was too good to be true.

I'm going to give Spybot Anti-Beacon a try. This is just stupid.

 

[dudeman509]

Well, Spybot Anti-Beacon seems to have done the trick. Didn't see it thrashing my disk last night.

 

[dudeman509]

Ugh, even with Anti-Beacon it manages to UNBLOCK the Telemetry services. Registry entry and task scheduler thing are still there.

Man this is annoying.

Delete the executable, CompatTelRunner.exe! Found in C:\Windows\System32 . You basically have to take ownership of the file, change your access, then you can delete. Worked for me until an update, after which I promptly deleted it again.

Detailed instructions here. See LiquidK's post.

Copied below for convenience (win10 instructions):

As an Administrative user, select your START menu.
In SEARCH box type compattelrunner.exe.
Right-click on the file titled compattelrunner and select OPEN FILE LOCATION.
Locate Compattelrunner.exe within the folder. Right-click and select PROPERTIES.
In the PROPERTIES windows, select the SECURITY tab.
Under the SECURITY tab, select the button labelled ADVANCED.
In the ADVANCED window, select the OWNER tab.
Under the OWNER tab, select CHANGE OWNER.
A list will now show of new owners. Select the account you are using and click APPLY.
A prompt will warn you that you must close all PROPERTIES windows to change ownership. Please do so.
Once again, Right-click on Compattelrunner.exe and select PROPERTIES.
Again, select the SECURITY tab.
Click the ADVANCED button.
Select PERMISSIONS.
Select the account you are using from the list.
A new window will appear with permissions options. At the top, select FULL CONTROL under the ALLOW column.
Click APPLY.
