+    .SYNOPSIS
+        Get custom event data from an event log record
+
+    .DESCRIPTION
+        Get custom event data from an event log record
+
+        Takes in Event Log entries from Get-WinEvent, converts each to XML, extracts all properties from Event.EventData.Data
+
+        Notes:
+            To avoid overwriting existing properties or skipping event data properties,
+            we append a prefix (default: e_) to these extracted properties.
+
+            Some events store custom data in other XML nodes.
+            For example, AppLocker uses Event.UserData.RuleAndFileData
+
+    .PARAMETER Event
+        One or more event.
+
+        Accepts data from Get-WinEvent or any System.Diagnostics.Eventing.Reader.EventLogRecord object
+
+    .PARAMETER Prefix
+        Append this to EventData keys to ensure uniqueness.  Defaults to e_
+
+    .INPUTS
+        System.Diagnostics.Eventing.Reader.EventLogRecord
+
+    .OUTPUTS
+        System.Diagnostics.Eventing.Reader.EventLogRecord
+
+    .EXAMPLE
+        Get-WinEvent -LogName system -max 1 | Get-WinEventData | Select -Property MachineName, TimeCreated, e_*
+
+        #  Simple example showing the computer an event was generated on, the time, and any custom event data
+
+    .EXAMPLE
+        Get-WinEvent -ComputerName DomainController1 -FilterHashtable @{Logname='security';id=4740} -MaxEvents 10 | Get-WinEventData | Select TimeCreated, e_TargetUserName, e_TargetDomainName
+
+        #  Find lockout events on a domain controller
+        #    ideally you have log forwarding, audit collection services, or a product from a t-shirt company for this...
