Windows Modules Installer Worker is not something that you downloaded at one point. It’s automatically built into the system and used to check for updates. Its use is to have the system update automatically and prevent and fix bugs. And while it works continuously without detection and problems to the system, sometimes it can become unresponsive and cause high CPU usage in the system, affecting the performance of you system. However, when those issues arise. While there are many methods out there, these have been thoroughly tested and are safe for you to use, and they work.
Most of the errors that occur with this can be seen on Windows 10, but older system users are not exempt. There have bee reports of it happening with Windows 7/8 users as well. The simplest fix for this would be to have the system stop running automatic updates. While it says recommended by automatic updates in the system, it could be causing you high CPU usage and an unresponsive system. Changing it to manual is easy. Hit Windows+R and enter services.msc, hit enter. Locate the Windows Modules Installer, open it with a double click, and change Startup Type from automatic to Manual. Do the same thing for Windows Update as well (follow the same steps above). After you have done all that, find windows update in the control panel, change settings, and select “check for update but let me choose whether to download and install them.” Then restart the computer and you should have no other issues.
Another easy method for reducing the CPU usage due to Windows Modules Installer Worker is to run the system under a clean boot. Here you can get rid of temporary files and service and processes and subsequently reduce CPU usage. Start out one again with Windows+R and search msconfig.exe. Once you find it and pen it select normal startup. Follow the prompts and restart your computer. That should be it. Once you restart you shouldn’t see another issue with CPU usage affecting your system.
If none of these work you could be running outdated system hardware. If that is the case then you will need to have that issue fixed as well. Sometimes an update is all that’s necessary.
High CPU usage can definitely be an issue when it comes to running a system smoothly and getting work done when you need it done. It can cause the system to become unbelievable slow or completely irresponsive, while it may not be the only reason your system is running slow, it could definitely be one of the main causes and that’s easy to determine in your tasks manager. Take the few moments to run through these fixes and hopefully you will end up with a lower CPU usage as a result.
