Many users encounter the TiWorker.exe process that uses a lot of CPU memory and don’t know if the process is a virus? In this article, Ticswipe will explain to you about TiWorker.exe and how to fix high CPU usage on Windows 10.
What is TiWorker.exe?
TiWorker.exe is a sub-process of TrustedInstaller.exe and is part of Microsoft Corporation services and part of the Windows Module Installer Service service stored on the computer in the “C:\Windows\servicing” folder, responsible for the updates of Windows on the computer.
Immediately after starting the computer, TiWorker.exe will be activated and use many CPU resources, causing the system to slow down. This is the main reason that many users suggest blocking this process.
However, this process should not be disabled or uninstalled as it may result in the computer not receiving important Windows security updates.
However, some malware impersonates the TiWorker.exe process to infiltrate the system. So before deciding to disable or uninstall, you should scan your computer for viruses or malware.
If Tiworker.exe on the computer is not a threat but often high CPU usage, it can be a problem. In that case, please do one of the solutions below that FPTShop guides to fix the above error.

Wait for the DISM scan to complete, which can take up to 15 minutes or longer.
After completing the system scan and check with both above commands, the system will reboot and you should check if TiWorker.exe high CPU usage problem is resolved or not.

Step 5: Now, go to the Services service again and double-click the Windows Update entry again.
Then, change the Startup type section from Manual to Automatic and click the Start button => Apply.
Step 6: Restart the computer and check if the problem is resolved.
Using clean boot mode helps to find out if any applications interfere with TiWorker.exe causing the computer to slow down.
To do a clean system boot, follow these steps:

After finding the problematic app, update or uninstall it
Clear all update history
Many users have reported that the computer’s temporary files can cause TiWorker.exe to slow down the system. So it is recommended to delete all temporary files from the system.
To delete temporary files, go to the C:Windows/Temp folder and find and delete the update folder. Then, restart the computer to apply the change.
Exclude TiWorker.exe from Windows Defender
It is found that Windows Defender keeps scanning for TiWorker.exe and thus increases CPU usage.
In that case, you should exclude TiWorker.exe from Windows Defender and the problem will be solved. Follow the steps to exclude TiWorker.exe from Windows Defender:
Step 1: Right-click the taskbar and select Task Manager to open the Task Manager window.
Step 2: Right-click TiWorker.exe and select the Open File Location option in the drop-down menu.
Step 3: Copy the path of this folder. Then activate Windows Defender Security Center by entering Windows Defender in the Search box next to the Start menu and then select the appropriate result.

Step 5: Then click on the Add or remove exclusions option under the Exclusion section.
Next click the Add an Exclusion button and select Folder in the drop-down menu. Now paste the folder path you copied above, and then close the dialog box.
From now on, Windows Defender will not scan TiWorker.exe and it will not slow down the computer. Restart the computer and check if the problem with TiWorker.exe is resolved.
