It allows Microsoft to ensure compatibility when you want to install the latest version of Windows OS.

This process is part of a Windows Update, specifically the KB2977759 one, which stands as the Compatibility update for Windows 7 RTM (Release to Manufacturer). The update is one of the many that serve as a preparation to upgrade to the latest OS version.

This process takes up storage bandwidth which may slow down your PC, and you will most likely want to get rid of it. Users complained of multiple CompatTellRunner.exe files showing up in the Task Manager consuming CPU and Disk Usage.

Though this process isn’t necessary and can be deleted if you do want Microsoft to diagnose your system by itself and run the compatibility checks, then let it run. This can be a privacy concern for some.

The CompatTelRunner.exe file is located in the System32 folder and is owned by the TrustedInstaller any modifications you try to do to it will be met with an “Access is denied” error, which means that you can’t modify or delete it in any way. This is because the process is owned by TrustedInstaller, and everything else only has a Read Only permission over it, and you can’t modify it.

There is a solution for the issue, and it involves taking ownership of the process, after which you can delete it without deleting the entire Windows update and save yourself from problems, OR you can let the program stay, and just disable Scheduled Tasks which launches the program.

Take ownership of CompatTellRunner.exe, and delete it afterward

The process is a fairly straightforward one, but make sure not to skip steps and keep in mind that you should be logged in as an administrator.

  • First of all, open your Start menu by hitting the Windows key on your keyboard, or by clicking the Windows icon at the end of the taskbar.
  • Type compattelrunner.exe in the search box, but don’t open the result, which is a file named compattelrunner, and instead, right-click on it and select Open file location from the drop-down menu or press the Windows Key and R.
  • Type C:WindowsSystem32 and type CompatTelRunner.exe in the search bar on the top right.

Once inside the folder, right-click the Compattelrunner.exe file within it, and select Properties from the menu. In the window that opens, you will notice a Security tab, select it and click on the Advanced button inside. Once the window opens, find the Owner tab, and select Change owner. This will give you a list of new owners, after which you should select the account you are using, and click Apply. You will be met with a prompt that warns you to close all Properties windows that are currently open in order to change the ownership, so close them.

When you’ve changed the owner of the file, next you should change the permissions. To do that, right-click the Compattelrunner.exe file again, and open Properties. Go to the Security tab and click Advanced once again. Within the window, select Permissions, and from the list that pops out, select the account you are using. You will see a new window with options about the permissions. At the top, under the Allow column, select Full Control and click Apply.

When you’re done with this, you are the owner of the file, not TrustedInstaller, and you have full control over it, meaning you can delete it without being met with the Access is denied error. Feel free to do so, and you won’t see it taking over much-needed resources from your system.
