Very often when we visit new customers, we find that they are running fully MDT integrated Task sequences. A closer look almost equally often reveals that they only use and need the Gather step.

So, as a lightweight alternative, when only using MDT for this simple task, we now recommend to instead run this PowerShell script near, or at, the top of the Task sequence. The script will create and populate what we have found being the most commonly used MDT variables. As from 2018-12-24 ("The @gwblok Christmas edition") the script can be run in debug mode, which produces an output similar to this:

PS C:\Temp> .\gather.ps1 -debug

Architecture = X64

AssetTag = 2587-8432-5072-7229-5119-1116-54

BIOSReleaseDate = 20180831000000.000000+000

BIOSVersion = Hyper-V UEFI Release v4.0

DefaultGateway = 192.168.100.1

IPAddress = 192.168.100.100

IsDesktop = True

IsLaptop = False

IsOnBattery = False

IsServer = False

IsVM = True

MacAddress = 00:15:5D:8A:94:1C

Model = Virtual Machine

OSCurrentBuild = 17134

OSCurrentVersion = 10.0.17134

ProcessorSpeed = 2394

Product = Virtual Machine

SerialNumber = 2587-8432-5072-7229-5119-1116-54

UUID = 200A47C7-5324-40BE-A30C-C3042D34D828

Vendor = Microsoft Corporation

VMPlatform = Hyper-V

When run in TSEnvironment "OSDComputerName" will be set to the same value as the built in "_SMSTSMachineName".

 

The script should be invoked as early as possible in the task sequence  

 

 

Advantages: Less maintenance, no MDT.

Disadvantage: You need the PowerShell optional component in your boot image.

 

Make sure to remember:

 

A special thank you to Gary Blok (@gwblok) for providing feedback and bringing energy to the refinement of this script.
