Is this a good tip to remove one kind of telemetry from Windows 7?

I read about this tip to remove one kind of telemetry from Windows 7. It's from 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)?

In it's present form this may not do anything.
Under HKEY_LOCAL_MACHINE\SYSTEM there will be a CurrentControlSet key plus ControlSet001 and possibly ControlSet002, ControlSet003, etc. One of the numbered control sets will be the active one. Typically it will be ControlSet001 but that will not always be the case. If it isn't any settings made there will do nothing. Generally it is best to make changes in the CurrentControlSet key which will always be the active one.

Do not interpret this as any kind of recommendation for the tip.
