PowerShell to create 100k local users

Add_Local_Users.ps1

# 1) The 100k users CSV file is here: https://docs.google.com/spreadsheets/d/1yPr_eutYWxUZX5ZhygvaMwi15aLVsjWNs275kQI4Q9A/edit?usp=sharing
# 2) Download it as a CSV, rename it to Users.csv in the directory of this script.
# 3) Run this script in an Administrator PowerShell prompt. It will take probably 10-20 minutes to complete.

$dataSource=import-csv "Users.csv"
foreach($dataRecord in $dataSource) {
  $displayName = $dataRecord.FirstName + " " + $dataRecord.LastName
  $userName = $dataRecord.FirstName
  New-LocalUser -Name $userName -FullName $displayName -Description "Test user" -NoPassword -Disabled
