The genuine ActionUriServer.exe file is a software component of Microsoft Windows Operating System by Microsoft Corporation. "ActionURIServer.exe" is the ActionURI Out-Of-Process (OOP) Server used by the Microsoft Cortana personal assistant to send information to Microsoft servers over a LAN or the Internet. As a component of Cortana which is a System App from the Windows Store, its proper location is "C:\Windows\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy\ActionURIServer.exe". (The string following "Cortana_" looks randomly generated but is always the same.) "Out-Of-Process Server" means that Cortana starts it in a separate thread and keeps running without waiting for it to finish. Apps, websites and other resources have unique Uniform Resource Identifiers (URIs) and a Cortana skill can be programmed by its developer (in C#) to use "LaunchURI" to activate a resource. "ActionURIServer.exe" is started by Cortana in its own thread whenever a skill being run by Cortana uses LaunchURI. Multiple instances, each in its own thread, can therefore be active at the same time.
