LAPS Powershell installation script for Domain controllers

Continuing with LAPS, if you don’t know what LAPS is you should read this

And take a look at my earlier post


Steps to Install

So, I created a powershell script that will help install LAPS on your DC and configure most of the things automatically tho there’s still a few steps that needs to be done manually which i will go through below. with that said i highly recommend you go through the documentation from Microsoft so you have a good understanding on what LAPS is and how to Install it manually and all the prerequisites before you use this script because this script doesn’t cover every installation scenario that’s possible and you need to be able to understand when this script is suitable and when its not and make the desired changes needed to make it work for your specific scenario.


1. Download the LAPS installation files from Microsoft

2. Copy the files to your Domain Controller you wish to install it on

3. Put the Install-DC.ps1 in the same folder as the installation files


     4. Create a security group that will contain members who will be able to read/reset the LAPS Password (For example a group called PwdAdmins)

      5. Navigate to the OU in AD where all the computer objects are located that you will manage

6. Remove Extended rights on all the groups that shouldn’t be able to retrieve or change the LAPS Password (For me information see Section 2.2.1 Removing Extended Rights in LAPS_OperationsGuide.docx document from Microsoft)


6. Open Powershell as an Administrator and navigate to the source folder

7. Run the following command Install-DC.ps1 -ADCompOU <Your OU> -ADUserGroup <Your user security group> (Example. Install-DC.ps1 -ADCompOU Win10PCs -ADUserGroup PwdAdmins)



The Script


param (
 [Parameter(Mandatory = $true, HelpMessage = 'AD OU that contains the computers you want to manage LAPS with')]
 [Parameter(Mandatory = $true, HelpMessage = 'AD Security group that contains users who should get access to read LAPS PW')]
 $Props = ("ADDLOCAL=Management.UI", "ADDLOCAL=Management.PS", "ADDLOCAL=Management.ADMX")
 foreach ($Prop in $Props)
 if ([System.Environment]::Is64BitProcess)
 msiexec /q /i LAPS.x64.msi $Prop ALLUSERS=2
 msiexec /q /i LAPS.x86.msi $Prop ALLUSERS=2
 Import-module AdmPwd.PS

 Set-AdmPwdComputerSelfPermission -Identity $ADCompOU
 Set-AdmPwdReadPasswordPermission -Identity $ADCompOU -AllowedPrincipals $ADusergroup
 Set-AdmPwdResetPasswordPermission -Identity $ADCompOU -AllowedPrincipals $ADusergroup


Until next time, cheers !

Quick overview of Local Administrator Password Solution (LAPS)

Quick overview of Microsofts Local Administrator Password Solution also known as LAPS from Microsoft.

Which gives you the ability to have periodical random generated password for the local administrator account for each machine while having it centrally managed and the possibility to retrieve the password for admins or certain people/groups that’s give access.

Having one or a set of predefined password for the local admin account on all of your PC’s is risky business and LAPS helps you mitigate that risk by auto-generating passwords for each computer.

Hardware inventory – Add firmware property to WMI class Win32_Diskdrive in ConfigMgr


There was a question on the Tech konnect facebook group the other day if there was any way of collecting disk name and firmware version from your clients in ConfigMgr.

Yes you can do this with the help of Hardware inventory and the Win32_DiskDrive WMI Class and use the following properties Caption and Firmware Revision but the thing is that the property Firmware Revision isn’t available by default so we need to add this
to the Win32_DiskDrive class in ConfigMgr Hardware inventory and i’m going to show you how to do this with the help of Powershell.


Getting started

First of all lets have a look on a Win10 client pc just to show of the information we want to gather. Caption is a good way of finding out the name and model of the disk tho different manufactures has there own way of naming things and then Firmware Revision to find out what firmware its running.


Get-WmiObject -Class Win32_DiskDrive | Format-List -Property Caption, Firmwarerevision




If we turn to ConfigMgr and Hardware Inventory classes Administration – Client Settings – <Your Client Setting> – Properties – Hardware Inventory – Set Classes

We can see that under the Win32_DiskDrive class we already have Caption but there’s no Firmware Revision property to be found.




Adding Firmware Revision to the Win32_DiskDrive class in ConfigMgr


We are going to this with the help of Powershell and here’s the script

Note: Make sure to modify the $Namespace variable so that the Site_Code is correct for your environment



#Modify Namespace to your correct Site ID
$Namespace = "root\SMS\site_TS1"

$Win32_DiskDrive = (Get-WmiObject -Namespace $Namespace -Class SMS_InventoryClass -ComputerName localhost | Where-Object {$_.ClassName -like "Win32_DiskDrive"})
$Classprop = [wmiclass]"$($Namespace):SMS_InventoryClassProperty"

$Prop = $Classprop.CreateInstance()
$Prop.PropertyName = 'FirmwareRevision'
$Prop.IsKey = $false
$Prop.Type = 8
$Win32_DiskDrive.Properties += [System.Management.ManagementObject]$Prop


Run the script on your ConfigMgr Siteserver



Go back to ConfigMgr and Administration – Client Settings – <Your Client Setting> – Properties – Hardware Inventory – Set Classes

and under Win32_DiskDrive you will now find “FirmwareRevision” and lets mark that checkbox and press “ok”



 Now you need to wait for the next Hardware inventory data to get back in to ConfigMgr and onces thats done you can go to “Assets and Compliance – Devices – <Right click on a Client> – Start – Resource Explorer”




 And from here go to “Hardware – Disk Drives” and double click on the row to the right which indicates the different disk and you will get a list of all properties and there you also have Firmware Revision




Now when you have the data in ConfigMgr  you can make a report out of it or build collections and so on.

Remote Software Center – Concept Preview

One thing always leads to another and that’s exactly how this project came to start. Last year i did a blog post on how to Invoke Software Updates remotely with Powershell and one on Applications and just last week i followed up on OSD Task sequence. Combining all of those with the mindset of trying to simplify tasks and helping people i started out to create this tool i call Remote Software Center.


What is Remote Software Center  ?

It’s a Windows Form GUI made in Sapiens Powershell Studio combined with Powershell scripting using WMI and CIM instructions to call different built in functions in Software Center.  The goal is to have the same and more functionalities as the Software Center application on each client but managed remotely instead so one does’t have to log on to the local computer to perform tasks you do inside in Software Center.


Current version is available for Download over at Technet both as .PS1 format and .EXE


Watch the video below to see it in action.


Current version


This is how it looks in its current form. First you need to enter a computer name and “connect” after that the comboboxes will populate with all the available software being OSD Task Sequence, Applications and Software Updates that’s available on the client.

More features will be added in the future.





Technical information

The script runs under current user context which means that you need to have the sufficient rights to access the other computer or else it won’t work.

More info will be added.





Would love to get some feedback and ideas on this, post your comment below or hit me up on twitter


Until next time, cheers Timmy !

Invoke OSD Task sequence remotely with Powershell


Earlier blog posts on invoking Installations:


Software Updates


This is a continuation on how to invoke or trigger installations in Software center remotely with the help of Powershell. This blog post came about after i got a question from a user called Sonik on the Application post i did.



Will this work to install Operating System as well? I have the operating system image available in the software center and It works when I manually select and install. But not with this script. Any idea?



Hey, No it won’t work because Configuration Manager uses different built in functions to trigger OSD then applications. I don’t know which WMI class it is right now but i will take a look and see if i can figure it out.


And below is the result on how to do it. Hope this will help you Sonik.


What do we want to Achieve?


We wan’t to be able to invoke an installation of an available OSD Task Sequence in Software Center remotely on a system.

One might wonder why and it’s pretty simple, it saves us time and we are lazy 😀



The Script


function Invoke-OSDInstall
[String][Parameter(Mandatory=$True, Position=1)] $Computername,
[String][Parameter(Mandatory=$True, Position=2)] $OSDName


$CIMClass = (Get-CimClass -Namespace root\ccm\clientsdk -ComputerName $Computername -ClassName CCM_ProgramsManager)
$OSD = (Get-CimInstance -ClassName CCM_Program -Namespace "root\ccm\clientSDK" -ComputerName $Computername | Where-Object {$_.Name -like "$OSDName"})

$Args = @{PackageID = $OSD.PackageID
ProgramID = $OSD.ProgramID


Invoke-CimMethod -CimClass $CIMClass -ComputerName $Computername -MethodName "ExecuteProgram" –Arguments $Args

End {}


The script is also available for download over at Technet




Until next time, cheers Timmy !

Making a GUI with Powershell Studio to run cmrcviewer.exe with logging



I did a blog post few weeks back talking about how to do logging with Cmrcviewer and powershell (Here)

That works great but if you intend to give it to someone else for example help desk you might wanna consider to make GUI for it instead of having a powershell-prompt running all the time and that’s exactly what i want to showcase on how to do a simple GUI with the help of Powershell Studio 2016 from SAPIEN. I’ve been using Powershell studio for almost a year now when i need to make a GUI and i really like how simple it is as soon as you understand how its works. They have a 45-day trial version where you can try it out with some limitations but i highly recommend you try it out.




Until next time, cheers Timmy !

SCCM – Find all powershell detection scripts for applications in your environment


Updated the script to only accept 1 variable and thats DestinationPath, the rest its now automated in the script so no need to specify Siteserver or SiteCode any more but you need to run the script locally on your Siteserver, the script is also now available on Technet. 


So the other day at the office i needed to use and create a detection script for a new application and before i started to write it i had a pretty good understanding on how i wanted it to look like and in that moment i thought “wait a minute, i think i have written something like this before for another application. Lets just reuse that one!”

Perfect idea! Only one problem tho…. I couldn’t for the life of me remember which application it was (typical me) . So in the hope of that it would be my lucky day i took a few minutes to randomly trying to go through some of the applications and see if i could find it manually in SCCM. And no, lady luck wasn’t on my side that day.

So i turned to my old friend Powershell and made script that would help me out.


What do we want to achieve?


We want to be able to get the Application name and the Powershell detection script for every application that uses powershell as detection scripts. When we have that information we out put it to a file which is named after the application and output the detection script in to the file.


The Script

 A description of the file.
[CmdletBinding(DefaultParameterSetName = 'DestinationPath')]
 [Parameter(Mandatory = $true,
 Position = 1)]

 [String]$Filepath = $DestinationPath
 $SiteCodeObjs = Get-WmiObject -Namespace "root\SMS" -Class SMS_ProviderLocation -ComputerName $env:COMPUTERNAME -ErrorAction Stop
 foreach ($SiteCodeObj in $SiteCodeObjs)
 if ($SiteCodeObj.ProviderForLocalSite -eq $true)
 $SiteCode = $SiteCodeObj.SiteCode
 $SitePath = $SiteCode + ":"
 Import-module ($Env:SMS_ADMIN_UI_PATH.Substring(0, $Env:SMS_ADMIN_UI_PATH.Length - 5) + '\ConfigurationManager.psd1')
 if (-not (Test-Path $DestinationPath))
 new-item -Path $DestinationPath -ItemType Directory -Force
 Set-location $SitePath
 $Apps = (Get-CMApplication)
 foreach ($App in $Apps)
 $Script = ([Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer]::DeserializeFromString($App.SDMPackageXML)).DeploymentTypes[0].Installer
 if ($Script.DetectionScript -ne $Null)
 $PSscript = ([Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer]::DeserializeFromString($App.SDMPackageXML)).DeploymentTypes[0].Installer.DetectionScript
 if ($PSscript.Language -like "PowerShell")
 Out-File -FilePath "$Filepath$($App.LocalizedDisplayName).ps1" -InputObject $PSscript.Text





Made this youtube video showing of how the script works



Until next time, cheers Timmy !
