Determine which Nodes have UAC Enabled with PowerShell

Wow!  It has been a while since I last blogged.  This has been a very busy year. Between my Navy activities and all the classes that I’m bringing online for clients, I am burning the candle at both ends.

As many of you know, my last day of a PowerShell class is “Project Day”.  One of the projects that I helped out with this week involved determining if UAC was enabled.  Utilizing the template we created in class and a check of the registry, we were able to:
  •         Remote to each client.
  •         Determine if the client was online.
  •         Report back the state of UAC.

I decided to advance the code just a little to make sure everything reports back as an object.  Below is that code.  Wish I had more time to explain it step by step, but I have to keep moving.  I only have 3 weeks to get everything done for PowerShell Conference Europe.




ForEach ($N in (Get-ADComputer -filter *).Name)
{
    $Obj = New-Object -TypeName PSObject -Property @{
        ComputerName = $Null
        UACEnabled = $Null
        Online = $False
    }
    Try
    {
        $Obj.ComputerName = $N
        $Data = Invoke-Command `
                -ComputerName $N `
                -ErrorAction Stop `
                -ScriptBlock {
                    (Get-ItemProperty `
                        -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System `
                        -Name EnableLUA).EnableLUA
                }
        $Obj.Online = $True
        If ($Data = 1) {$Obj.UACEnabled = $True}
        Else {$Obj.UACEnabled = $False}
    }
    Catch {$Online = $False}
    Write-Output $Obj

Adding a Comment to a GPO with PowerShell

As I'm writing this article, I'm also writing a customization for a PowerShell course I'm teaching next week in Phoenix.  This customization deals with Group Policy and PowerShell.  For those of you who attend my classes may already know this, but I sit their and try to ask the questions to myself that others may ask as I present the material.  I finished up my customization a few hours ago and then I realized that I did not add in how to put a comment on a GPO.  This is a feature that many Group Policy Administrators may not be aware of. This past summer I attended a presentation at TechEd on Group Policy.  One organization in the crowd had over 5,000 Group Policies.  In an environment like that, the comment section can be priceless.  I always like to write in the comment section why I created the policy so I know its purpose next week after I've completed 50 other tasks and can't remember what I did 5 minutes ago. In the Group Policy module for PowerShell V3, th

Return duplicate values from a collection with PowerShell

If you have a collection of objects and you want to remove any duplicate items, it is fairly simple. # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   # Remove the duplicate values. $Set1 | Select-Object -Unique 1 2 3 4 5 6 7 What if you want only the duplicate values and nothing else? # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   #Create a second collection with duplicate values removed. $Set2 = $Set1 | Select-Object -Unique   # Return only the duplicate values. ( Compare-Object -ReferenceObject $Set2 -DifferenceObject $Set1 ) . InputObject | Select-Object – Unique 1 2 This works with objects as well as numbers.  The first command creates a collection with 2 duplicates of both 1 and 2.   The second command creates another collection with the duplicates filtered out.  The Compare-Object cmdlet will first find items that are diffe
