This can be frustrating, but fear not, as we have the solutions you need to get your PC back to optimal performance.

Understanding Windows Modules Installer Worker

The “Windows Modules Installer Worker” is a vital component of your PC. Its primary role is to automatically check for and install Windows updates, ensuring your system remains secure and up-to-date. This process runs quietly in the background, but it can become a nuisance when it starts hogging your CPU resources.

Is Windows Modules Installer Worker a Threat?

Before we dive into solutions, let’s address a common concern: Is Windows Modules Installer Worker malware? The answer is no; it’s not malware. It’s an integral part of Windows Updates.

Why Does Windows Modules Installer Worker Cause High CPU Usage?

The culprit behind the high CPU usage is often the Windows Modules Installer Worker’s relentless quest for updates.
