Using CompatTelRunner.Exe, you can install the newest version of Windows or any other Service Pack Upgrades on your computer. If you’ve signed up for Microsoft’s Customer Experience Improvement Program,
the CompatTelRunner.Exe can also diagnose your machine for compatibility issues and collect programme telemetry data. During the process of updating to the most recent version of Windows, you can use this tool to verify compatibility.
A specific Windows Update, KB2977759, is the focus of this procedure. It looks at the Windows 7 RTM compatibility updates (Release to Manufacturer). This update is one of many that serves as a prelude to upgrading to a newer version of the operating system.
Because it causes your PC to run slowly, everyone want to have this process removed. CompatTelRunner.Exe files in the Task Manager drain CPU and Disk Usage, according to several of the customers.
If you don’t require it, you can delete it, however running the compatibility checks will help you diagnose the system on your own. The TrustedInstaller is in control of this file, which is located in the Sytsem32 subdirectory.
“Access is denied” will pop up if you try to change this. Simply put, this implies you can’t remove it or change it in any way. Because TrustedInstaller is the process’s owner, it can only perform Read Only permissions on it. As a result, you are able to alter or customise it.
It’s as simple as taking ownership of the process, after which you can either delete it without uninstalling the entire Windows update, or you can simply disable the Scheduled Tasks which execute the application and leave your problem in place.
