    TiWorker is a WMI (Windows Modules Installer) Worker Process which is related to Windows Update. Usually, the error occurs after an update has run. In this fix, i will list 5 methods which you can use to attempt and stop tiworker from consuming your CPU.

    If a process, is utilizing the entire or a portion of CPU, then it can slow down the computer and the performance of apps running on it. It can also overheat the CPU since it’s constantly utilizing all available threads to process the requests by the process which in this case is TiWorker.exe

    How Disable Tiworker.exe

    1.Press Ctrl+Shift+Esc key combination to open the Task Manager. Locate the “Windows Modules Installer” process and click on the End Task button. This process will re-spawn again and again so keep terminating it every 10 seconds to be able to work with your Windows PC (or it will freeze your system).

    2.Press Win+R to open the Run dialog. Type services.msc in the Run dialog and press Enter. This will open the Services management interface.

    3.Locate the service named Windows Update, right-click on it and select Stop. This will halt the service responsible for launching the TiWorker.exe program.

    4.Double-click on the Windows Update service in the Service manager interface. Select Startup type to be Disabled and click on the OK button.

    5.That’s it, now you can work with your computer without being interrupted by the Windows Modules Installer. After you are done working, just reverse all the steps so that Windows can install updates it wants.
