Unwanted browser extensions and hidden background processes can quietly eat up system resources and drag down your PC’s performance. Often, apps keep running or leave behind clutter even after you’ve closed or uninstalled them. Taking a few minutes to audit your startup items, extensions, and active processes goes a long way.

This guide covers straightforward ways to spot and get rid of digital clutter without jumping through hoops. For a more thorough cleanup, tools like IObit Uninstaller can also help strip away stubborn software and sweep up leftover registry files to keep Windows running smoothly.

Part 1: Tips for Managing Unwanted Extensions and Hidden Background Apps 

Managing unwanted extensions and hidden background apps is important for keeping your PC fast, secure, and responsive. Here are some tips that you can use to manage unwanted extensions and hidden background apps: 

1.  Review Installed Extensions Regularly

Reviewing installed extensions regularly is one of the best methods to manage unwanted extensions. Over time, you may install extensions for specific tasks and later forget about them. Here is how to review installed extensions on Google Chrome: 

• Open Google Chrome and click on the three-dot menu in the top-right corner. 
• Select “Extensions” and then click “Manage Extensions.”

• All installed extensions will appear on your screen. Review each extension and identify any that you no longer use. 
• Finally, click on the “Remove” button to uninstall unwanted extensions from Google Chrome. 

2. Check Background Apps 

Hidden background apps can consume CPU, RAM, disk space, and network resources even when you are not actively using them. Regularly checking which applications are running in the background can help you identify unnecessary programs and improve your PC’s performance. Here is how to check background apps on Windows. 

• Press Ctrl +  Shift + Esc to open Task Manager. Next, click “Processes” to view the apps and background processes currently running. 

• Check the CPU, Memory, Disk, and Network columns to identify apps using excessive system resources. 
• Select an unnecessary application that you recognize and click on the “End Task” option. 

3. Uninstall Unwanted Extensions and Apps 

If all the above methods fail to manage unwanted extensions and apps, the final step is to completely remove them from your PC. For this purpose, choose a reliable uninstaller for Windows like IObit Uninstaller.
