Microsoft has created a number of configurations or extension files to help with the upgrading process. CompatTelRunner.exe is one of these update file extensions.

The addon ensures the device’s compatibility while updating the operating system version.

The user has the option of not allowing this software to execute, thereby saving time. If you need to confirm compatibility before installing the latest operating system, you can use the Windows installer to do so.

What Is CompatTelRunner.exe and How Do I Fix It?

CPU and disc use are both high. Every difficulty, fortunately, has a feasible answer. One approach is for the administrator to take control of the installation process before proceeding to remove the extension file from the computer. Another option is to allow only the ‘Scheduled files’ to run while the operating system is being installed. Let’s take a quick look at how to fix the CompatTelRunner.exe High CPU and Disk Usage issue.

Method 1: Corrupt System Files

The file should, in theory, not occupy so much CPU and storage space. If the machine has corrupt system files, this can happen. Thankfully, the operating system includes a little yet powerful command prompt tool called System File Checker (SFC).

Step 3 – The Administrator command prompt will appear on the screen. To use the system file checker (SFC) utility, type the following command and press enter:

sfc /scannow sfc /scannow sfc /s

Step 4 – Finally, replace all of the system’s corrupt files.

To make the updated settings take effect, restart the computer. During the installation of a new operating system, it might solve the problem of high CPU and disc space utilisation.
