Windows UIPI blocks AI agents from controlling elevated apps

By PulseAugur Editorial · [1 sources] ·

A common issue for computer-use agents on Windows is their inability to interact with elevated applications like Task Manager or Registry Editor. This limitation stems from Windows' User Interface Privilege Isolation (UIPI), which prevents lower-integrity processes from controlling higher-integrity ones. Consequently, agents running at a Medium integrity level cannot send synthetic input, window messages, or discover UI elements in elevated applications, even though they can still capture screenshots. The problem can be diagnosed by checking the integrity levels of both the agent and the target application, and potential solutions include running the target application without administrator privileges, or elevating the agent itself for specific tasks.

    Your computer-use agent's clicks do nothing in admin windows on Windows

    <p>Your agent drives Windows fine all day. Then it reaches Task Manager, an elevated terminal, Registry Editor or an installer, and everything stops working at once: the element list comes back empty, the click tool returns "ok", and nothing on screen moves. The screenshot still …
