What’s ServiceUI.exe (ServiceUI Application)? Is it safe or a virus?

ServiceUI.exe is a utility included in the Microsoft Deployment Toolkit (MDT) that facilitates interaction between system-level processes and the active user session. It enables user interface elements of applications running under the SYSTEM account to be visible and interactive for the logged-in user. This is particularly useful in deployment scenarios where user interaction is required during automated installations or configurations.

ServiceUI.exe is used to display user interface elements from system-level processes to the logged-in user. For example, in deployment scenarios, it allows scripts or applications running under the SYSTEM account to present prompts or dialogs to the user. By specifying the user process (e.g., explorer.exe), ServiceUI.exe ensures that the interface appears in the correct user session. This is particularly useful when deploying applications via tools like Microsoft Intune, where installations run in the system context but require user interaction.

As a Windows user, you might encounter ServiceUI.exe during software installations or updates that require your input, even though the process runs with system-level privileges. For instance, if your organization deploys applications via Microsoft Intune, ServiceUI.exe enables the installation process to display prompts or dialogs directly to you, facilitating necessary interactions during the setup. This ensures that, despite the underlying process operating with elevated permissions, you can provide inputs or make selections as needed.
