Specific tip to remove one type of telemetry from Windows 7

Much has now been written about removing telemetry from Windows 7.

But one recommendation I don't find often is from the useful website AskVG.com:

Our reader "Xircal" shared some useful information with us. Even if the user opts out of the CEIP program, another task called "Microsoft Compatibility Appraiser" continues to relay data to Microsoft via a log file called "AutoLogger-Diagtrack-Listener.etl" present in "C:\ProgramData\Microsoft\Diagnosis\ETLLogs\AutoLogger\" folder.

You can disable this Compatibility Appraiser task using following steps:

1. Press WIN+R keys together to launch RUN dialog box, type regedit in RUN and press Enter. It'll open Registry Editor.




2. Now go to following key:

   
   

   HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\WMI\AutoLogger\AutoLogger-Diagtrack-Listener

   
   

   In right-side pane, change the value of Start DWORD to 0 to turn off the auto logger program.




3. Again go to following key:

   
   

   HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\WMI\Autologger\AutoLogger-Diagtrack-Listener{DD17FA14-CDA6-7191-9B61-37A28F7A10DA}

   
   

   In right-side pane, look for the DWORD Enabled. Its value would be set to 1 by default. Double-click on the DWORD and change its value from a 1 to 0 to disable the task.

Restart your computer to take effect.

Besides not contributing to Microsoft's massive volume of collected data, are there any downsides to following this tip? Does it break anything (except sending telemetry data to Microsoft)?
