This PC – Set to Hostname

Image

Set This PC to Machine’s hostname

This is a very simple idea, but a bit tricky to implement. The idea is, enabling the "This PC" icon on the desktop, then rename it to the actual name of the computer. This is a handy and simple help desk tool, when requesting the computer name.

This PC 01

Deployment Methods

  • Intune*
  • ConfigMgr
    • Package
    • Baseline
    • Task Sequence*

*Methods I’ll cover

I’m going to Cover the Intune method, and the Task Sequence method, basically all other methods are just different ways of running the PowerShell Script.

Intune

I’ve uploaded the script to GitHub which can be leveraged in Intune.

In Intune:
This PC 03

Script creates logs:
This PC 04

Finished Product:
This PC 05

Task Sequence Step

This PC 02

While this example is an embedded script, it’s long enough I recommend creating a powershell file and placing it in a Package and calling it from there, but for development, this was faster.

Code


<#
.SYNOPSIS
    --.Replace "This PC" icon name with the actual name of the PC
