TiWorker.exe: What is it and Fix High CPU Usage
TiWorker.exe (Windows Update Trusted Installer Worker Process) is a Windows Update Service-related process and people updating or downloading updates commonly see it in their Task Manager. It is a system process that is basically assigned with the task of managing and installing/uninstalling the Windows Updates. It will startup automatically with Window bootup.
When there is a new update available, Windows will inform you about it and you can choose whether you would like to update it now or when the computer is not in use.
