Answer 1

Hi,

Welcome to Q&A platform.

The Windows Compatibility Telemetry is a service in Windows Server 2019 which contains technical data on how the device and its related software is working. It periodically sends the data to Microsoft for future improvement of the system and to enhance the user experience. We would suggest you do not disable this service. If you really want to disable it, please try the following detailed steps to see if it was helpful:

Click Start, type Task Scheduler, and then press Enter.

On the TaskScheduler window, go to this path: Task Scheduler Library\Microsoft\Windows\Application Experience.

On the Application Experience folder, look for Microsoft Compatibility Appraiser.

Right-click on it, select Disable, and then confirm to complete the process.

Next, please run the following command in an elevated command prompt:

sc delete DiagTrack
sc delete dmwappushservice
echo “” >
C:\ProgramData\Microsoft\Diagnosis\ETLLogs\AutoLogger\AutoLogger-Diagtrack-Listener.etl
reg add HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection /v AllowTelemetry /t REG_DWORD /d 0 /f

Best Regards,
Sunny

Answer 2

There were some bugs in the commands. This is a fixed and shortend version.

Step 1. Disable schedule for Windows Compatibility Telemetry.

WCT is a service which contains technical data on how the device and its related software are working. To disable it:

1. Click Start, type Task Scheduler, and then press Enter.
2. On the Task Scheduler window, go to this path: Task Scheduler Library\Microsoft\Windows\Application Experience.
3. On the Application Experience folder, look for Microsoft Compatibility Appraiser.
4. Right-click on it, select Disable, and then confirm to complete the process.

Step.2. Disable Microsoft's Diagnostic Tracking.

Next, please run the following command in an elevated cmd (*).

This will remove tracking services:

sc delete DiagTrack  
sc delete dmwappushservice  

Note that I don't know what is this logger for, but as was noted above this seems to be a keylogger log file for the diagnostics service. This command replaces it with empty text to delete the logged data:

echo. > c:\ProgramData\Microsoft\Diagnosis\ETLLogs\Autologger\AutoLogger-Diagtrack-Listener.etl  

This adds a registry key titled "AllowTelemetry" and sets the key to 0, to disable the telemetry:

reg add HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection /v AllowTelemetry /t REG_DWORD /d 0 /f  

(*) Note, to run elevated cmd:

1. Press Windows key and type cmd. This should find the Command line program. Note that searching by "cmd" works in any language version of Windows.
2. There should be an option to Run as administrator. Use it.

Answer 3

Regedit should be entered at the Run prompt by simultaneously pressing the Windows key and R. Click OK. Click Yes when the User Account Control window appears.
Click HKEY LOCAL MACHINE > SOFTWARE > Policies > Microsoft > Windows > DataCollection to access it now. Right-click on DataCollection in this window and choose New > DWORD (32-bit value). Double-click this new value after giving it the name Allow Telemetry. Value data should be changed to 0 (zero), then OK.

Answer 4

What does all this do and why isnt just disabling the option not enough?

sc delete DiagTrack
sc delete dmwappushservice
echo “” >
C:\ProgramData\Microsoft\Diagnosis\ETLLogs\AutoLogger\AutoLogger-Diagtrack-Listener.etl
reg add HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection /v AllowTelemetry /t REG_DWORD /d 0 /f

Before I blindly trust the internet and mess with my registry, I sure would like to know what it is doing and why.
