Modern Setup Host or SetupHost.exe is is a self-extracting archive and installer, located in C:\$Windows.~BT\Sources\ folder, which runs as a scheduled task every time a user logs in, to execute a process with the local user’s privileges within the context of its parent windowsstoresetupbox.exe. It is required when you are running the setup to upgrade your PC to Windows 10. If it fails for some reason, you see this error and the upgrade process aborts.

A few precautionsĀ  you could take first. If you have installed any 3rd party antivirus or firewall sofware, disable it. Disconnect all the unnecessary external devices connected to the computer. Some are reporting that a Low Disk Space can cause this problem. So ensure you have sufficient Disk Space of at least 20GB. Having done this, go through the list and see what could suit your system the best.

1] Perform a Clean Boot and see if you are now able to carry out the installation.

2] Others have said that changing Language helped. So change Language to English (United States) and setĀ  a match Windows display language, including System Locale to English (United States). See if this works for you.

3] From the WinX Menu, select Run. Type the following path and hit Enter:

C:\Windows\SoftwareDistribution\Download

Now Select all the contents and delete everything in this folder.

Next, from the WiX Menu, click on Command Prompt (Admin), type the following command and hit Enter:

wuauclt.exe /updatenow

Restart your computer and start the upgrade process again.

4] Ben Wil has suggested the following solution. Download and run the Windows 10 Media Creation tool. Let it download and verify the download. Once this process is completed, close the tool and pressWinKey+R to open the Run box.

Paste this path and hit Enter:

C:\$Windows.~WS\Sources\Windows\sources\setupprep.exe

    Thanks – have had this 5 times now – no thanks at all to Microsoft as a Service.
    It may be free – but how do we get our valuable time back from Microsoft?
    Will start by uninstalling MalwareBytes

    Modern Setup Host Has Stopped Working windows 10

    I solved this problem by finding an obscure post by some
    guy probably scratching himself strategically while collecting food stamps rather than relying on the zillion dollar Microsoft company and their team of Tech Monkeys! This should work but please follow carefully!
    1. Click the update to Windows 10 button.
    2. Choose to copy to USB (3GB min) or DVD.
    3. open the usb or dvd you just made and click setup
    4. When it loads save time and choose not to update at this
    time.
    5. It will go through the entire process of installation, BUT,
    6. Follow this carefully, you will get a pop up error message “Modern setup host not working- close program” DO NOT HIT CLOSE PROGRAM!!!! HIT CONTROL, ALT, DELETE/ TASK MANAGER AND RESTART WINDOWS. THERE SHOULD BE A RESTART BUTTON ON THE LOWER RIGHT AFTER YOU HIT C/A/D. CHOOSE RESTART AND YOUR UPDATE WILL FINISH WHEN IT REBOOTS.
    7.Just another reason why Microsoft sucks!!!

    Boilerplate- use at your own risk.

    This didn’t work for me. Windows just restarted without continuing the install.
