How to disable the Microsoft Compatibility Telemetry service

Windows 10 has many new features, among which there are also new telemetry and data collection functions that collect all of your user data and send it back to Microsoft. Despite the fact that Microsoft has marked this feature as a way to improve user interaction. Nevertheless, many users accuse the company of spying on you.

Disable the Microsoft Compatibility Telemetry service.

Microsoft Compatibility Telemetry - what is this service

Most of us are against sending your personal data to Microsoft. In addition, some users reported that the Microsoft Compatibility Telemetry process recently began to cause very high disk utilization in the Windows 10 system. Many users report that after upgrading to Windows 10, they ran into problems with a place on the hard drive. Users have reported this problem as a disk issue in Windows 10.

The Microsoft telemetry capability is provided through the diagnostic tracking service and is fully enabled. Microsoft recently released updates for Windows users (KB3075249, KB3080149, and KB3068708), which offer identical telemetry data. This feature is very important for maintaining Windows 10 — it collects data from the computer and sends it back to the Windows developers. Now Microsoft claims that it collects information to improve user interaction and improve the Windows platform to simplify it.

If you have been using Windows 10 for a long time, you noticed that Microsoft's telemetry compatibility is enabled by default, but suddenly it starts using a huge amount of PC resources and slows down the OS. Everyone is concerned about their privacy in Windows 10. But still, many users of Windows 10 are concerned about this automatic data collection. After disabling the settings, you can relax and stop worrying about your privacy in Windows 10.

Why Microsoft Compatibility Telemetry loads a disk or processor

Microsoft Compatibility Telemetry is a service in Windows 10 that contains technical data on how Windows devices and related software work, and periodically sends this data to Microsoft to improve user interaction, eliminating potential problems that may arise. Using Microsoft Compatibility Telemetry:

  • Allows Windows to be updated.
  • Allows the system to be safe, reliable and work well even in adverse situations.
  • Allows the system to personalize or customize user interaction and OS.
  • Improves Windows performance with cumulative processor analysis.

What is Windows telemetry data and why does Microsoft Compatibility Telemetry load a Windows 10 disk? This data includes basic information about system diagnostics, logs of how often you use functions and applications, system files, and, apparently, more data that has not yet been disclosed. All of these data types fall under the telemetry category. The following are specific examples of Windows Telemetry data:

  • Typed text is sent every 30 minutes.
  • Everything you say into the microphone.
  • Transcripts of what you say while using Cortana.
  • The index of all media files on your computer.
  • The first data from the webcam - 35 MB.

MCT deactivation

The following are some of the methods by which you can turn off Microsoft Compatibility Telemetry in Windows 10.

Using command execution

At the command prompt, enter the following lines:

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

Reboot your PC and make sure that the process in Windows 7 is disabled.

Using the list of services

Start the services:

  • Click Win + R, then type services.msc.
  • Find the Diagnostics Tracking Service in the list.
  • Open its properties and select "Disabled".

Reboot your PC and test Windows 8 and other versions.

Using parameters

There are several basic ways to disable Microsoft Compatibility Telemetry using the CompatTelRunner.exe file, but before that you should know what CompatTelRunner.exe is and what it does.

What is CompatTelRunner.exe

This is the process that is used to upgrade your OS to the latest version or make related changes. The process is part of Windows Update, in particular, KB2977759, which acts as a compatibility update for Windows 7 RTM (developer edition). It requires high bandwidth storage, which can slow down your PC, and you most likely will want to get rid of it. Users complained about the numerous CompatTellRunner.exe files displayed in Task Manager, which use the CPU and hard disk. It is used to perform diagnostics on a PC to determine if there is a possibility of compatibility problems, and it collects program telemetry information if it is included in the Microsoft Software Quality Improvement Program. The process allows Microsoft to ensure compatibility when you install the latest version of Windows.

The file CompatTelRunner.exe is located in the System32 folder and belongs to the TrustedInstaller. Any changes you are trying to make to it will be accompanied by an “Access Denied” error, which means that you cannot change or delete it in any of the available ways. This is because the telemetry process is owned by TrustedInstaller, which has a read-only attribute, and you cannot change it. Although the process is not necessary and can be optionally removed, so that Microsoft can diagnose your system on its own and run compatibility checks and then allow it to work. For some, this may be a privacy issue.

How to troubleshoot high CPU and disk utilization with CompatTelRunner.exe

Microsoft's telemetry service uses high CPU resources and a lot of disk space, so use the following tips to resolve this issue.

Method 1: Disable CompatTelTunner.exe from the task scheduler:

  1. Hold down the Windows key and press R. Type in taskschd.msc and click OK.
  2. Expand Task Scheduler Library / Microsoft / Windows / Application Experience
  3. Right-click each of the tasks listed in the Microsoft Compatibility Appraiser one by one and select Disable.

Using the registry

  1. On the keyboard, simultaneously press the Windows logo key and the R key to invoke the Run command.
  2. Type regedit and click OK.
  3. Press YES when prompted for account control.
  4. Go to HKEY_LOCAL_MACHINE / SOFTWARE / Policies / Microsoft / Windows / DataCollection
IMPORTANT. If you cannot find Allow Telemetry, then to create it, right-click the DataCollection and select New-DWORD (32-bit), then name the new Allow Telemetry value.
  1. Double click Allow Telemetry.
  2. Set the Value to 0 (zero) and click OK.

So, now you can successfully disable telemetry for compatibility with Microsoft for Windows 10. If the problem with using the hard disk persists, try other methods described below.

Using Group Policy

  1. On the keyboard, simultaneously press the Windows logo key and the R key to invoke the Run command.
  2. Enter gpedit.msc and click OK.
  3. Navigate to Computer Configuration / Administrative Templates / Windows Components / Data Collection and Preview.
  4. Double-click Allow Telemetry.
  5. Select Disabled, then click OK.

Using a third-party program

To turn off the service, you can use any software or system optimizer. All of them work according to the same principle - launch the application, click on the “Scan PC” button and wait until the end of the analysis. After that, the program will show all damaged files and programs, as well as settings that must be changed to optimize Windows.

TIP. It's all! Now you can delete the file CompatTelRunner.exe. When you are done with this, you will become the owner of the file, not the TrustedInstaller, and you will have complete control over it, that is, you can delete it without encountering the error "Access Denied". Do this and you will no longer see how the process takes much-needed resources from your system.
