What is the Modern Installation host?

It is widely used and developed by Microsoft, but it is not without its bugs, so Microsoft releases updates to fix them occasionally. In order to install these updates, some operating system components are integrated into the computer. The updates are downloaded directly to the computer and then installed by some components.

During the installation of the main update, the modern installer host normally runs in the background. It is typically located in the $Windows.BT folder and is downloaded and installed automatically by the computer. Windows 10 upgrades are carried out by this host.

What is the Modern Setup host’s CPU and disk usage?

Computer resources and hard drive space can be consumed by Modern Setup host for several reasons.

A slow hard drive is used to download an important update.
The SetupHost.exe process is being slowed down by other resources or tasks.
Your antivirus program is infected with malware that mimics SetupHost.exe.

To rule out the possibility of catching a virus, run anti-virus software on your computer. If not, follow the solutions below if Modern SetupHost still consumes all of your resources.

Diagnostics and troubleshooting for Windows Update should be run first
To use DISM, follow these steps.
Restart your computer
If you use a computer with a default language, check it.
Delete all software distribution items.
Make sure your computer is not updated by Windows Update.

Run Windows Update Troubleshooting

It’s possible to run the Windows Update diagnostic program, which is integrated into Windows 10, to fix Windows Update errors. The diagnostic program may need to be downloaded from the Microsoft website if you’re running Windows 7 or Windows 8.

Running Windows Update diagnostics on Windows 10 is as simple as following these steps:

Open the Start menu by pressing the Windows logo key.
You can find troubleshooter in the results by typing “troubleshooter” into the search box.
Run the troubleshooting tool after clicking Windows Update.
The troubleshooter must confirm that all problems have been identified and resolved.
1.) Proceed to Fix 2 if the problems were not detected or marked as “Not Fixed”.
Our knowledge base has many articles on how to resolve Windows Update issues that are marked “Uncorrected” in the problem information.

The steps for Windows 7 and 8 are as follows:

The Microsoft troubleshooter can be downloaded here.
To run the downloaded file, double-click it once it has been downloaded.
3. Click the Next button and then select Windows Update.
Check that all problems have been identified and resolved by the troubleshooter.
Then proceed to Fix 2, if the problem wasn’t detected or was marked Uncorrected.
The information in our knowledge base can help you fix the problem if the problem is labeled “Uncorrected”.

Generally, Windows 10, 8 and 7 devices have high CPU usage caused by Modern Setup Host.

If the problem disappeared, great. If it returned, try something else. If you ran Windows Update or updated your computer and still have the problem, this may be an indication that is a problem with a modern install host. If this doesn’t work, try something else.

Use the DISM tool.

An error may prevent Windows Update from working correctly, so you can try restoring Windows images using the built-in DISM command-line tool.

Your computer needs the following software to run DISM:

Open the Start menu by pressing the Windows logo key.
Choose Run as administrator when you choose Command Prompt or cmd in the results by right-clicking them.
Note: Click Yes if prompted by User Account Control.
After typing each command, press Enter:
Online Cleaning /Scan for Health /DISM.exe
A health check is performed by DISM.exe/Online/Image Cleaning/Health Check
Run the DISM.exe command online, clean the images, and check the system’s health.

In order to verify that Modern Setup Host is working correctly, run a Windows update or refresh your computer once the commands have been executed. If the problem has been solved, you will know what to do next.
The third solution should be used if the problem returns.

Do a complete reboot.

It is possible that background programs interfere with Windows updates.
Rebooting Windows will resolve the problem because a minimal set of drivers and programs will be installed when you reboot.

The runtime window is opened when you hold down the Windows logo key and press the R key.
Press Enter after typing msconfig.
The Load Startup Items checkbox needs to be cleared on the General tab of the system configuration.
Then click Disable all of the Microsoft services beneath the Services tab.
Open Task Manager by clicking the Start tab.
You can disable startup items that are enabled by right-clicking each one in the Task Manager’s Start tab.
Under System Configuration, click the OK button once again on the Start tab.
The computer should be rebooted.

In the event that a problem persists, reinstall Windows or update the computer to your own specifications. If the problem went away after reinstalling Windows or updating the PC, keep trying. If the problem continues, don’t give up and move onto solution 4.

You can check the default language of your computer.

It is possible to experience problems with Windows Update if the language of your system interface is not the same as the language of your system language.

As a result, ensure your system’s language is set to the one you installed.

Note: If you are not sure about the default system interface language, follow these steps to check it:

You can open the Start menu by pressing the Windows Logo key.
Select Run as administrator from the results when you type cmd.
Note: Click Yes if prompted by User Account Control.
The default user language should now appear after typing /online /get-intl.

Modern Setup Host High Cpu

Windows Updates could get interrupted unexpectedly, resulting in corrupt files being built up, which could cause Modern Setup Host to hang and consume a lot of CPU.

If you are unsure of the language of your system, follow these steps:

Steps to install Windows 10 are as follows:

The settings window will be opened when you press the Windows logo key on the keyboard.
You can change the time and language by clicking on them.
The language must be selected as the system’s default language. Select the region.

Check Windows Update or update your computer if the Advanced Setup Host language is set to a different language.
Go to Fix 5 if you have already set the language as the default language.

Windows 7 users should follow these steps:

Open the Startup window by pressing R and holding the Windows logo key.
You must enter the control before pressing Enter.
Tap Area and Language when you have selected the large viewing icons.
It is important that the system user interface is set to your native language.
The installation of a Windows update or updating the PC will resolve the problem if a different language is set as the default.
In this case, go to Fix 5 if the language has already been set to the default language on the system user interface.

All items in the software distribution folder should be removed.

During Windows Update installation, you need to store temporary files in a folder called Software Distribution.

Software Distribution folder temporary files may sometimes prevent Windows Update from working.
For the purpose of getting rid of these files, follow these steps:

In the runtime window, press R after pressing the Windows key.
Using the path C:WindowsSoftwareDistributionDownload, copy and paste it.
In the download folder, select all the files using Ctrl and A simultaneously, then right-click and select Delete.
Choose Do this for all items if you are asked to grant administrator privileges.
The computer should be rebooted.

Restarting your computer will help you determine if the Modern Setup Host problem remains. Alternatively, you can update your computer at your convenience.

It appears that the modern setup host issue on your computer has been resolved for now. If you continue to experience problems, you may refer to solution 6.

Disable Windows Update from your computer

Alternatively, you can disable Windows Update on your computer if you do not wish to install Windows Update and do not wish to upgrade to Windows 10.

The following steps will help you disable Windows Update:

You can open the startup window by pressing the Windows key, then pressing R.
Press Enter to open services.msc.
You can access the properties of the Windows Update service by right-clicking it in the Services window.
The startup type should be set to Disabled on the General tab, and the application should be stopped.
