Fix: Microsoft Compatibility Telemetry High Disk Usage Windows 10

Windows Telemetry data includes basic system diagnostics information, system files, logs of how frequently you use an application or feature, and likely more metrics which are not yet known. This module collects and sends data to Microsoft servers so they diagnose problems using the set amount of data they collected.

Although this is a useful tool for helping Microsoft further improve user experience, many people recently reported that this process was causing an unusual amount of disk usage. These spikes in disk usage can be continuous or may occur from time to time. Although one cannot completely disable the telemetry service, we can try shut down some of its modules and check this solves the problem.

Solution 1: Disabling Telemetry Using Group Policy Editor

We can try to disable the telemetry service using the group policy editor. It is possible that some versions of Windows might not have group policy editor installed. You can check out our other article on how to add group policy editor to your version of Windows (if you don’t already have it).

  1. Press Windows + R to launch the Run application. Type “gpedit.msc” in the dialogue box and press Enter.
  2. Now navigate to the following file path using the navigation pane present at the left side of the screen:

Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds.

  1. Double-click on the entry “Allow Telemetry” to open its settings. Set the key to “Disabled”. Press Apply to save changes and exit.

  1. Restart your computer and check if this solves the problem at hand. You can check the usage by press Windows + R and typing “taskmgr”.

Solution 2: Disabling Telemetry using Registry Editor

Another workaround to disable the telemetry services is to change some keys in the registry editor. Do note that a registry editor is a powerful tool. If you change keys which you have no idea of, you might risk your computer becoming non-functional.

  1. Press Windows + R to launch the Run application. Type “regedit” in the dialogue box and press Enter.
  2. Once in the registry editor, navigate to the following file path:

HKEY_LOCAL_MACHINE > SOFTWARE > Policies > Microsoft > Windows > DataCollection.

  1. Double-click the key of “AllowTelemetry” present at the right side of the screen to change its value.

  1. Set the value to 0 (zero). Press Ok to save changes and exit.

  1. Restart your computer and check if the usage got better. You can check the usage by press Windows + R and typing “taskmgr”.

If you don’t see the key “AllowTelemetry” in the DataCollection folder, right-click it and select “New > DWORD (32-bit) Value”. Set the name as “AllowTelemetry” and set its value as 0 (zero).

Note: You might require administrative privileges to perform this method. Make sure that you are logged in as an administrator.

Solution 3: Disabling CompatTelRunner.exe using Task Scheduler

We can also try disabling a specific process using the task scheduler. Any process in the task scheduler may have a time set. After that elapsed time, the process will start executing and will keep executing until the job is done. You can always revert the changes using the same method if this doesn’t work for you.

  1. Press Windows + R to launch the Run application. Type “taskschd.msc” in the dialogue box and press Enter.
  2. Once in the task scheduler, navigate to the following file path:

Task Scheduler Library > Microsoft > Windows > Application Experience

  1. At the very top of the entries listed, you find a task named “Microsoft Compatibilty Appraiser (CompatTelRunner.exe)”.

  1. Right-click it and select “Disable” from the list of options available.

  1. Restart your computer and check if the usage got better. You can check the usage by press Windows + R and typing “taskmgr”.

If the problem still persists at this stage, we can try taking ownership of the process executable and rename/change permissions so it will not run automatically. Do note that you require administrative access to follow this solution.

  1. Press Windows + E to launch the File Explorer. Navigate to the following file path:

C:WindowsSystem32

  1. Search for the executable file named as “CompatTelRunnner.exe”. Right-click it and select Properties.
  2. Navigate to the Security tab and select “Advanced” at the near bottom of the window.

  1. At the near top of the window, you will see an option “Change” in front of the owner. Click it.

  1. A new window will pop up asking you to select the User or Group for the owner. Click on “Advanced”.

  1. Click on “Find Now” for all the user groups to be listed in front of you. Select your account from the list of items and click on “OK” for it to be added to the list.
  1. Press “OK” for the owner to be changed. Then press “Apply” on the window which comes forth. You are now the owner of the file. Close the properties and open them again for the changes to be implemented.

  1. After opening the properties again, click on “Change permissions”. Now you should only add “Modify and Change” permissions to the administrator. This way if you ever need to access the executable again, you will have to open the permissions and just add “Execute” and this executable will be not be executed automatically as you just took away all the executing permissions.

Furthermore, remove all the listed permissions to be on the safe side.

  1. Restart your computer and check if the problem is solved.

Note: You can also delete the executable if it keeps running or rename it so you can use it again when needed.
