Check the task manager for any processes maxing out resources on the machine. We have found that CompatTelRunner.exe was maxing out the machines CPU, which was affecting the exam driver.
Prevent CompatTelRunner.exe From Running In Windows.
To do so, press the Windows key and then search for Task Scheduler. Then click it from the search result to open Task Scheduler.
In the next step, navigate to the following address below:
Task Scheduler Library >> Microsoft >> Windows >> Application Experience
There should be three tasks on the list. You need to choose “Microsoft Compatibility Appraiser “, right-click on it and select the “Disable” option.
After that, reboot your Windows computer to test if the issue persists or not.
In case the high usage issue caused by CompatTelRunner.exe remains, you should also disable “ProgramDataUpdater” as sometimes it can call the CompatTelRunner.exe to run.
