(199) Microsoft Intune - Rename devices with PowerShell

Previous posts I have covered with setting a hostname or prompt for computer name.

Manually renaming a single device is simple, but managing a large fleet requires automation for efficiency. While the standard CSP method exists, it can be inconsistent—especially regarding console reporting.

To solve this, I’m sharing a PowerShell script that integrates with Microsoft Intune to streamline and automate your device renaming process.

This script detects the type of device used for a virtual machine or physical machine, it will retrieve the serial number and add the prefix: IGG

To prepare the win32 app, you will need:

Install.ps1

Just rename the prefix to whatever you like under $Prefix

#Variables
    $Date = Get-Date
    $CurrentName = (Get-CimInstance -ClassName Win32_ComputerSystem).Name
    $Prefix = "IGG"
    $Logs = "C:\ProgramData\MrBSOEWay\logs\RenameComputerToIGG.log"

#Delete old Logs files
    Remove-Item -Path $Logs -Force

#Computer Name 
    Write-Output "$($Date) : The current computer name is $($CurrentName)" | Tee-Object -FilePath $Logs -Append

#Check Platform type
    $ComputerType = (Get-ComputerInfo).CsSystemFamily
    If($ComputerType -eq "Virtual Machine")
        {
            Write-Output "$($Date) : Platform detection - $($ComputerType) : using an automatically generated computer name." | Tee-Object -FilePath $Logs -Append
            $Serial = (Get-CimInstance win32_bios).serialnumber
        }
    else
        {
            Write-Output "$($Date) : Platform detection - $($ComputerType) :  using the service tag to generate the computer name." | Tee-Object -FilePath $Logs -Append
            $Serial = (Get-CimInstance win32_bios).serialnumber
        }

#Change Computer Name
    Write-Output "$($Date) : The script change the computer name because it's not compliant with the naming convention" | Tee-Object -FilePath $Logs -Append
    Rename-Computer -NewName "$($Prefix)$($Serial)" -Force
    Write-Output "$($Date) : The new computer name is $($Prefix)$($Serial)" | Tee-Object -FilePath $Logs -Append
        
#Send message to user for request computer restart & reboot
    Shutdown -r -t 120 -f -c "Your administrator has implemented changes. To finalize the process, we will reboot your computer in 2 minutes."

Detect.ps1:

if (test-path "C:\ProgramData\MrBSOEWay\logs\RenameComputerToIGG.log"){"Installed"} 

Once the app is deployed, end users will receive this message:

After the device has been restarted, on logon you will notice the hostname has changed.

Similarly with that on the Intune portal, it will reflect the name change.
