A process or a service utilizing high CPU resources in Windows 10 is quite a common occurrence. The TiWorker is one such process that often troubles users because of its high CPU usage. The TiWorker.exe process in Windows is a Windows Module Installer Worker process. It is associated with Windows Update, and you will usually notice this process consuming unusually high CPU resources after a Windows Update.
The TiWorker is an essential process that initiates and runs in the background as Windows boots. Now, the process is supposed to occupy significantly fewer CPU resources. Usually, the process occupies CPU space in MBs, which is not an issue. Things go wrong when this Windows Module Installer Worker process starts to consume very high CPU usage, sometimes rocketing to more than a GB. When this happens, you will face PC slowing down and programs lagging, as there are significantly fewer resources for Windows and other programs to run.

The SFC scan is another Windows utility that comes pre-loaded with the OS. It is a command-line tool that requires a Command Prompt to work. By running this scan, your PC will look for problematic or corrupt system files on your PC. When found, these files are fixed automatically.
Step 1: Open Command Prompt with admin privileges. To do so, press the Win + X keys on your keyboard. Now, a menu will open up. Here, select the Command Prompt (Admin) option.

Now, check the Task Manager to see if the TiWorker.exe process is still utilizing high CPU resources.
Run DISM Scan
The DISM scan is another powerful Windows utility with the capability to fix issues in your PC. Using this tool, you can try to fix Windows Module Installer Worker high CPU usage issue. Here’s how:

Dism /Online /Cleanup-Image /RestoreHealth
Again, wait till the DISM scan is complete. This scan usually takes more time to complete than the SFC scan. So, be patient and do not close or interrupt the scan while running; else, you might run into other troubles.
After the DISM scan is complete, reboot your PC and look for issues.
