What’s UIEOrchestratorStub.exe (Undocked UIEOrchestrator Stub)? Is it safe or a virus?

UIEOrchestratorStub.exe, by Microsoft, is a system process related to the Windows user interface experience. It acts as a placeholder or "stub" for managing and orchestrating undocked user interface elements, such as when the system transitions between different modes or layouts (e.g., tablet or desktop mode).

This executable helps coordinate UI adjustments to ensure seamless functionality and visual consistency in dynamic scenarios. It's a legitimate component of Windows and typically operates quietly in the background, aiding in the efficient handling of interface-related tasks. Interfering with this process is not recommended, as it may disrupt normal system behavior.
