PS Oneliner to get local device compliance state

Getting local Azure AD / Intune device compliance state with a PowerShell Oneliner

The Graph API and Intune portal(s) give insight into device compliance status, but what about a local equivalent? How can we locally detect from e.g. a script on a Windows 10 laptop if the device is compliant or not?

I couldn’t find any documentation, WMI properties or registry keys, but I did find that the Company Portal shows the compliance status and caches this in a file. So, although it isn’t pretty, I’ve settled for this method for now and created a UserVoice item requesting a local W10 API/regkey/WMI property to query Intune compliance status of the device.

((get-content -Path (Get-Childitem –Path (Join-Path $env:LOCALAPPDATA `
-ChildPath "Packages\Microsoft.CompanyPortal_8wekyb3d8bbwe\TempState\ApplicationCache") `
-Include *.tmp* -File -Recurse | sort-object -Descending -Property lastWritetime)[0] | convertfrom-json).data | convertfrom-json).ComplianceState

Using pipeline identity for Connect-AzureAD, Graph and other endpoints

Azure Pipelines and Azure Functions (and Automation Accounts) can have managed identities, in other words, a service principal. This service principal can be assigned to Azure AD roles (e.g. to modify users / devices) or graph / Azure RM resources. A service principal could even be a global admin, and Service Principals don’t have to do MFA…. 🙂

In both Pipelines and Functions the new Az module is enabled and logged into your tenant by default as the service principal, how cool would it be to use that identity to do those (hopefully few) things that are still only supported by e.g. the AzureAD module?

Here’s an example on getting tokens for Azure AD and for Graph, obviously you could also get tokens for other audiences the same way:

$context = [Microsoft.Azure.Commands.Common.Authentication.Abstractions.AzureRmProfileProvider]::Instance.Profile.DefaultContext
$graphToken = [Microsoft.Azure.Commands.Common.Authentication.AzureSession]::Instance.AuthenticationFactory.Authenticate($context.Account, $context.Environment, $context.Tenant.Id.ToString(), $null, [Microsoft.Azure.Commands.Common.Authentication.ShowDialog]::Never, $null, "").AccessToken
$aadToken = [Microsoft.Azure.Commands.Common.Authentication.AzureSession]::Instance.AuthenticationFactory.Authenticate($context.Account, $context.Environment, $context.Tenant.Id.ToString(), $null, [Microsoft.Azure.Commands.Common.Authentication.ShowDialog]::Never, $null, "").AccessToken

Write-Output "Hi I'm $($context.Account.Id)"

Connect-AzureAD -AadAccessToken $aadToken -AccountId $context.Account.Id -TenantId $

get-azureaduser -Top 5

If you want to do this from an old fashioned Azure Runbook (please move to functions!) then you’ll have to log in to Az first:

    $servicePrincipalConnection = Get-AutomationConnection -Name "AzureRunAsConnection"
    Connect-AzAccount -Tenant $servicePrincipalConnection.TenantID `
        -ApplicationId $servicePrincipalConnection.ApplicationID   `
        -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint `
}catch {
    Write-Error -Message $_.Exception
    throw $_.Exception
