What is TiWorker.exe?TiWorker.exe is a subprocess of TrustedInstaller.exe and is part of the Windows Module Installer Service. It is located on the computer in the “C:WindowsInstaller” directory. This module is responsible for Windows updates on the entire computer. It therefore runs in the background of Windows and checks whether the latest Windows updates are available. In general, this module does not consume any system resources (RAM, CPU or hard disk) during operation. As soon as the update process is completed, TiWorker.exe releases the computer’s resources again. However, in some cases it has been observed that the TiWorker.exe process consumes a large amount of CPU resources immediately after starting the computer and runs very slowly. Therefore, it is necessary to stop the execution of TiWorker.exe. Note: Do not disable or uninstall this process as this may prevent your computer from receiving important Windows security updates.
Why is TiWorker.exe Causing a High CPU?TiWorker.exe causes a problem where CPU usage is high for several reasons:
