Update Task Sequence, DP info in registry

Hello Friends,

Is there a way I can know which task sequence is used to deploy a particular machine?

Yes, we can update the registry key with the Task Sequence info like, which Task Sequence is used to deploy the OS on a particular machine?

from Which DP the contents are downloaded? Is the machine built with Boot media or it is PXE boot?

Is this a machine desktop or laptop? what is the machine type, machine model?

Also, we can get when the machine is imaged(date and time when the Task Sequence is deployed).

First, we have to gather all the information which we want to update in the registry.

let's take the example of DP's name...

How do we know from which DP the contents are getting downloaded? from where I can get this information? is it a simple variable which I can use to update the registry? No.

While running the Task Sequence all the variable data is stored in a .dat file and we can fetch that using "New-Object -ComObject 'Microsoft.SMS.TSEnvironment"

The value against "("_SMSTSLastContentDownloadLocation")" will be found in the above string.

now the DP name we have to convert from the long file path to the FQDN and then we have to store it in the PowerShell variable. 

then we can use the same in the registry to update the info like "Set-ItemProperty -Path Registry::HKLM:\SOFTWARE\$OSDBrandingName -Name DPInformation -Value $DPName -Force -Confirm:$false" Create $OSDBrandingName and $DPName variable before update the registry path.

In the $DPName variable use $DPvalue.Substring($startIndex, $endIndex-$startIndex) value from Task Sequence varible 

for other veriable like whethermachine is desktop or laptop, you can get this infor from the Task Sequence variable("New-Object -ComObject 'Microsoft.SMS.TSEnvironment") only.

OS version and build number I have fetched from registry only. like in Windows Operating System it is stored in the registry path-"HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\currentBuild" or "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\releasedID".

Also, you can add your custom variables also and update the registry to get more info about OSD.

In the below PowerShell script I have covered most of the above things. let's create an SCCM package using the below PowerShell script and distribute it on the desired DPs.

Add this package in the Task Sequence anywhere post WinPE stage or SCCM client is installed (the first reboot is completed).

don't forget to bypass the PowerShell in Task Sequence and share the feedback😀👍👍
