+.SYNOPSIS
+    Exports a list of users and the last PC they logged into.
+
+.DESCRIPTION
+    Queries Domain Controller security event logs for interactive logon events (4624)
+    to determine which computer each user last authenticated from.
+
+.PARAMETER OutputPath
+    Path for the output CSV file. Defaults to current directory.
+
+.PARAMETER DaysBack
+    Number of days of event logs to search. Default is 7.
+
+.PARAMETER LogonTypes
+    Array of logon types to include. Default is 2 (Interactive) and 10 (RemoteInteractive/RDP).
+
+.EXAMPLE
+    .\Get-UserLastLogonComputer.ps1
+
+.EXAMPLE
+    .\Get-UserLastLogonComputer.ps1 -OutputPath "C:\Reports" -DaysBack 30
+
+.NOTES
+    Must be run on a Domain Controller with appropriate permissions to read Security logs.
+    Logon Type 2 = Interactive (console)
+    Logon Type 10 = RemoteInteractive (RDP)
+    Logon Type 11 = CachedInteractive
