Collect Autopilot hashes without big user interaction?

I ended up using a "custom" version of the Get-WindowsAutoPilotInfo process.
Rather than running locally I created a script that would run it, export to a CSV based on the PC name and export to Azure Blob storage or you could export to a file share if you'd prefer:

I then set a PowerShell script to run from Intune, you could use SCCM I guess also if that is what you use.

you could use the append option to create a single file in a network share. I used Azure Data Factory to merge the CSV's in to one list once it had run.

#Setup the basics: Folder, Path etc...
New-Item -Type Directory -Path "C:\HWID"
Set-Location -Path "C:\HWID"
$env:Path += ";C:\Program Files\WindowsPowerShell\Scripts"
Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned

#Install NuGet and the Get-AutoPilotInfo scrript
Install-PackageProvider -Name NuGet -Force
Install-Script -Name Get-WindowsAutoPilotInfo -force

#Add your AzCopy path to the Windows environment PATH
$userenv = [System.Environment]::GetEnvironmentVariable("Path", "User")
[System.Environment]::SetEnvironmentVariable("PATH", $userenv + ";C:\HWID\AzCopy", "User")

#Get the Hardware ID:
Get-WindowsAutopilotInfo -OutputFile "$env:COMPUTERNAME.csv"
#Copy the CSV to Azure Blob Storage
.\azcopy.exe copy "c:\HWID\$env:COMPUTERNAME.csv" "https://mystorage.blob.core.windows.net/autopilot?sp=rw&st=2023-04-10T13:30:52Z&se=2023-08-30T21:30:52Z&spr=https&sv=2021-12-02&sr=c&sig=0A8QGSprlAQJH%2B0cMZdwRL%2Fasdwerwfds45435%$£dfdg" --recursive
