Do you have a slow computer and the Task Manager shows you a process called Modern Setup Host highly consuming your system’s CPU and Memory? You might also come across an error message like “Modern Setup Host has stopped functioning” while trying to upgrade to Windows 10 from Windows 7.

Before we dig deeper into the topic in this post, we will first brief you up on what exactly is this process? You need to comprehend its function and then be informed about the fixes when this error leads to high CPU usage by the Modern setup host process.

What is Modern Setup Host?

It is basically an installer that is located in a self-extracting archive within the $Windows.BTSources folder. In other words, this is a self-extracting archive and installer that triggers system updates. It circumstantially shows up on systems that runs the Windows beta system version (Windows Technical Preview).

This process appears to be running in the background of computers when it is installing an update or is running the installation setup file to upgrade a computer from Windows 7 to Windows 10. The Modern setup host itself functions within the context of the parent Windowsstoresetup.exe (which is directly executed by Microsoft Windows Update).

Thus, users can see an error when they are trying to upgrade to Windows 10 but they won’t b able to complete the upgradation process without fixing this error.

Troubleshoot methods to fix Modern Setup Host error:

DISM.exe /Online /Cleanup-image /Checkhealth

DISM.exe /Online /Cleanup-image /Restorehealth.

Once the scanning process is complete, verify if the problem has resolved or it persists.

3. Perform Clean Boot

Sometimes, high CPU usage due to Modern setup host can occur if the Windows Update fails due to interferences from background programs. A clean boot can be performed to deal with this problem as per the following steps:

• Open the Run dialog box by pressing Win key + R key.
• Type “msconfig” to open the System Configuration window.

• Under the General tab of the System Configuration window, uncheck the ‘Load startup items’ box.

• Under the Services tab, check the box which says ‘Hide all Microsoft services’ and then click on the ‘Disable all’ radio button.

• Then, switch to the Startup tab and open Task Manager by clicking on it.

• Now, on the Startup tab of Task Manager, every startup item that shows up has to be disabled by clicking right on the items and choosing the ‘Disable’ option.

• Then, move back to the Startup tab of the System Configuration window and select the ‘OK’ option.
• Finally, restart your computer to see if the problem still persists or has resolved.

4. Use the Ideal Default System Language

Windows Update may encounter a problem if the language of the system is not the same as that of the default language of the system UI. Windows 10 users can check what is the default system language by the following steps:

• Go to the Start menu and open the Command Prompt window by typing “cmd” and select the ‘Run as Administrator’ option by utilizing the right-click option.

• Enter the following command and press the Enter key to see the default system UI language:

dism /online /get-intl

To check the setup system language, use the below steps:

• Go to the Windows Settings.
• Select the Time & Language option and then click on the Language segment.

• This should display the language on the right-hand side pane which is currently set up on your computer. If you notice a contradiction here, then change it to match the default system UI language. If this doesn’t resolve the issue, then use the following method to solve the Modern setup host high disk usage issue.

5. Empty the Software Distribution Folder

The software distribution folder is responsible for storing all the important temporary files required for Windows Update. However, if too many files occupy the folder, then it may create an interference with the Windows Update. To remove unnecessary files, you can try to utilize the following steps:

• Go to the Run dialog box by holding and pressing together the Windows key + R key.
• Using the below path, go to the respective location and then select all the files and delete them from the folder.

C:\Windows\SoftwareDistribution\Download

• Further, restart your PC and verify if the problem persists.

6. Disable Windows Update

Finally, if the above fixes did not solve the problem at hand, then you must be wondering what can be further done to resolve the Modern setup host issue.

• Open the Run dialog box and input “services.msc” in the type box to open the Services window.

• Here, right-click on the Windows Update to select the ‘Properties’ option.
