# Set MDM Enrollment URL's  
$key = 'SYSTEM\CurrentControlSet\Control\CloudDomainJoin\TenantInfo\*'  
$keyinfo = Get-Item "HKLM:\$key"  
$url = $keyinfo.name  
$url = $url.Split("\")[-1]  
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\CloudDomainJoin\TenantInfo\$url"  
  
New-ItemProperty -LiteralPath $path -Name 'MdmEnrollmentUrl' -Value 'https://.../discovery_windows' -PropertyType String -Force -ea SilentlyContinue;  
New-ItemProperty -LiteralPath $path  -Name 'MdmTermsOfUseUrl' -Value 'https://.../enroll_windows' -PropertyType String -Force -ea SilentlyContinue;  
  
# Trigger AutoEnroll
