10 Easy Fixes TiWorker.exe High CPU Usage? | How To Fix. High CPU performance issues related to Tiworker.exe have been reported by many Windows users, including the latest version of Windows 11. Tiworker.exe is constantly running in the background, checking for and downloading system updates.
This is the reason why it causes problems with high CPU load and in many cases causes Windows to stop working.
If you are also wondering how to avoid high disk load problems, in this guide we will show you some possible ways to solve the high CPU load problems of the TiWorker.exe process in Windows.
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:
- Windows is out of date.
- WindowsWorker is outdated. Windows is old. Third-party applications installed at some point are consuming a lot of disk space and causing the problem.
- The stack update service compresses some Windows update files and causes a problem with the TiWorker.exe file.
- Sometimes the problem occurs when playing games or running demanding applications.
It has also been detected that some malware is present in the TiWorker.exe file. Therefore, it is recommended that you scan your computer with a good antivirus program for viruses or malware before proceeding to solve the problem.
