Windows updates are essential to improve your overall PC performance, security patches, upgrades features, and also offers fixes for many errors. While the updates are downloaded straight to your PC, the installation is done by some components that come integrated with the OS. One of the components include the Modern Setup Host that’s supposed to run in the background whenever the update is getting installed.
However, some users have been experiencing this problem where they see “Modern Setup Host causing high CPU usage” error in Windows 10 or another error message “Modern Setup Host has Stopped Working“. Fortunately, there are a couple of ways to fix this issue. Let’s see how.
Method 1: Through the Settings App
Step 1: Go to Start, click on it and select Settings from the menu.
Step 2: In the Settings window, click on System.
Step 3: In the System settings, on the left side of the pane, click on Notifications & actions.
