Fix TiWorker.exe High Disk Usage on Windows 10

Many Windows 10 users are faced with the fact that the TiWorker.exe or Windows Modules Installer Worker process loads the processor, disk, or RAM. Moreover, the load on the processor is such that any other actions in the system become difficult.

This manual details what TiWorker.exe is and why it can load a computer or laptop. What can be done in this situation to fix the problem, and how to disable this process?

What is the Windows Modules Installer Worker (TiWorker.exe) process?

First of all, what is TiWorker.exe – this is a process launched by the TrustedInstaller service (Windows Module Installer) when searching for and installing Windows 10 updates, during automatic system maintenance, and when turning Windows components on and off (in Control Panel – Programs and Features – Enable or disable components).

You cannot delete this file: it is necessary for the correct operation of the system. Even if you somehow delete this file, this will likely lead to the need to restore the operating system.

It is possible to disable the service that starts it, which we will also talk about, but to fix the problem described in the current manual and reduce the load on the processor of a computer or laptop, this is not required.

Regular operation of TiWorker.exe can cause high CPU usage

In most cases, the fact that TiWorker.exe loads the processor is the regular work of the Windows Modules Installer. Typically, this happens when automatically or manually searching for Windows 10 updates or installing them. Sometimes – when servicing a computer or laptop.

In this case, it is usually enough to wait for the module installer to complete its work, which on slow laptops with slow hard drives, as well as in cases where updates have not been checked and downloaded for a long time, can take a long time (up to hours).

If there is no desire to wait, and there is also no certainty that the matter is in the above, you should start with the following steps:

  • Go to Settings (Win + I) – Update and Recovery – Windows Update.
  • Check for updates and wait for them to download and install. Windows 10 update options
  • Restart your computer to finish installing updates.

And one more option, probably the regular operation of TiWorker.exe, which I had to deal with several times: after the next turn on or restart of the computer, you see a black screen (but not like in the article Windows 10 Black Screen), by Ctrl + Alt + Del you can open the task manager and the Windows Modules Installer Worker process is visible there, which heavily loads the computer. In this case, it may seem that something is wrong with the laptop: but after 10-20 minutes, everything returns to normal, and the desktop loads (and does not repeat anymore). This happens when the download and installation of updates are interrupted by restarting the computer.

Issues with Windows Update 10

The following most common reason for the strange behavior of the TiWorker.exe process in the Windows 10 Task Manager is the incorrect operation of the Update Center.

Here you should try the following methods to fix the problem.

Automatic error correction

The built-in troubleshooting tools may be able to help solve the problem use which following steps:

  • Go to Control Panel – Troubleshooting and select “View All Categories” on the left.
  • Run the following fixes: System Maintenance, Background Intelligent Transfer Service, and Windows Update. Automatically fix Windows Modules Installer Worker.

After the execution is complete, try searching for and installing updates in the Windows 10 settings. After installing and restarting the computer, see if the Windows Modules Installer Worker problem has been fixed.

Manual fix for Update Center issues

If the previous steps didn’t solve your TiWorker issue, try the following:

The manually clearing the update cache (SoftwareDistribution folder) from the article Windows 10 updates does not download.

Suppose the problem appeared after installing any antivirus or firewall and possibly a program to disable spyware features in Windows 10. This could affect the ability to download and install updates. Try temporarily disabling them.

Check and restore the integrity of system files by launching the command prompt as Administrator through the right-click menu on the Start button and entering the command dism /online /cleanup-image /restorehealth. Perform a clean boot of Windows 10 (with third-party services and programs disabled) and check if the search for and installation of updates in the OS settings will work.

If everything is in order with your system as a whole, then about one of the methods by now should have helped. However, if this does not happen, you can try alternative options.

How to disable TiWorker.exe?

The last thing I can suggest in terms of solving the problem is to disable TiWorker.exe in Windows 10. To do this, follow these steps:

  • In the task manager, clear the task from Windows Modules Installer Worker.
  • Press the Win+R keys on your keyboard and type services.msc.
  • In the list of services, find “Windows Modules Installer” and double-click on it.
  • Stop the service, and set the startup type to “Disabled.” Disabling the Trusted Installer Service.

After that, the process will not start. Another option for the same method is to disable the Windows Update service. Still, in this case, manually installing updates will disappear (as described in the article about non-downloadable Windows 10 updates).

Additional Information

Sometimes this can be caused by incompatible devices or their proprietary software at autoloading. In particular, it was encountered for HP Support Assistant and services for older printers of other brands. After removal, the load disappeared.

If a process is causing an interfering workload in Windows 10, this is not the result of problems. You can set the priority for the process to low in the task manager: in this case, it will take longer to do its job, but TiWorker.exe will have less of an impact on what you do on your computer – setting the priority of the TiWorker.exe process.

We hope some of the suggested options will help rectify the situation. If not, try to describe in the comments after which the problem arose and what has already been done: maybe we can help.
