Windows™ impersonation is a mechanism that allows Campaign administrators to associate Campaign users with Windows™ users, so that Campaign processes invoked by a Campaign user run under the credentials of the corresponding Windows™ user.

For example, if Windows™ impersonation is enabled, when the Campaign user jsmith edits a flowchart, a unica_acsvr process starts under the Windows™ user ID associated with the Marketing Platform login name, jsmith.
