Automation windows for attended or unattended automations are disclosed. A child session is created and hosted as a window including the UIs of applications of a window associated with a parent session. Running multiple sessions allows an automation to operate in this child session while the user or another automation interacts with the parent session. The user or other automation may thus be able to interact with applications that the automation is not using or the user or other automation and the automation may be able to interact with the same application if that application is capable of this functionality. Changes made via the automation and the user or other automation in an application will be made as if a single user made them, rather than having the user or other automation and the automation each work with separate versions of the applications and file systems.
