Most documentation scripts will also create formatted text and HTML output so Microsoft Word is not required.

C:\ScriptTesting > .\Get-GPOTimeV2.ps1 [-ComputerName <String>] [-InputFile <String>] [-OrganizationalUnit <String>] [-Folder <String>] [<CommonParameters>]

By default, builds a list of all computers where “Server” is in the OperatingSystem property unless the ComputerName or InputFile parameter is used.

The script must be run from an elevated PowerShell session.

Process each server looking in the Microsoft-Windows-GroupPolicy/Operational for all Event ID 8001.

Displays the Average, Minimum, and Maximum processing times.

All events where processing time is 0 are ignored. A 0 time means a local account was used for login.

Display the results on the console and creates two text files, by default, in the folder where the script is run.

Optionally, can specify the output folder.

Unless the InputFile parameter is used, needs the ActiveDirectory module.

The script has been tested with PowerShell versions 2, 3, 4, 5, and 5.1.
The script has been tested with Microsoft Windows Server 2008 R2, 2012, 2012 R2, and 2016 and Windows 10 Creators Update.

There is a bug with Get-WinEvent and PowerShell versions later than 2 or culture other than en-US, the Message property is not returned.

There are two work-arounds:
1. PowerShell.exe -Version 2
2. Add this line to the script:
[System.Threading.Thread]::CurrentThread.CurrentCulture = New-Object “System.Globalization.CultureInfo” “en-US”
