High usage of the CPU often leads to overheating or excessive fan noise, which ultimately leads to poor computer performance, including program freezes, lags, and other problems.

Although any program on a computer can cause this problem, some users have reported finding Windows Modules Installer Worker as the process responsible for high CPU usage via Task Manager.

This is a common problem that most people worry about and look for a solution. Fortunately, this article explains the Windows Modules Installer Worker’s high CPU usage and how to fix the problem without getting into a jam. Read on!

What Is Windows Modules Installer Worker?

​Windows Modules Installer is a system process on Windows computers that is responsible for automatically checking for and installing Windows updates and removing the updates.

This process, which is part of the Windows operating system, is crucial for Windows PCs as it keeps the computer up-to-date and protects it from security vulnerabilities.

Contrary to what some PC users believe, Windows Modules Installer Worker – also known as TiWorker.exe – is not malware. It keeps your computer up-to-date by checking for and installing Windows updates in the background.

Common Causes of Windows Modules Installer Worker High CPU Usage

In most cases, installing Windows updates – which is performed by the Windows Modules Installer Worker – is a CPU -intensive process and can result in high CPU -usage, which can be typical. However, there are some cases where the process irregularly consumes a lot of CPU power, which leads to poor computer performance and even overheating that can damage PC hardware.

If Windows Modules Installer Worker CPU consumes a lot of power irregularly, it may be because there is a problem with the Windows update that is being installed on your computer or you are installing the wrong updates. On the other hand, the problem can also be due to corrupted system files, malware infections, or corrupted drivers.

In the next part of this article, we will present the best solutions to the problem with the high usage of Windows Modules Installer Worker ( CPU ), based on the possible causes of the problem and the measures that have already helped some users to solve the problem.

How to Fix Windows Modules Installer Worker High CPU Usage

1. Press Windows + R to open the Run utility, then type regedit and press Enter.

2. In the Registry Editor window, navigate to the following path:

HKEY_LOCAL_MACHINE > SOFTWARE -> Microsoft > Windows NT > CurrentVersion > NetworkList > DefaultMediaCost

3. Right-click the DefaultMediaCost key and select Permission from the drop-down menu.

4. In the resulting dialogue box, click Add.

5. Enter your user name in the Enter the object names to select box, select Check Names, and click OK.

6. Now select the user you just added, check the Allow box in front of Full Control, and click OK.

7. In the right pane with the values under DefaultMediaCost, double-click the Ethernet value.
