Multi threading in ADDRS

I’ve added basic multi-threading to ADDRS:

This solely ensures that the most compute intensive task (caching sizes/performance) is not repeated between jobs. You’ll still have to handle running multiple jobs using your own preferred method, e.g. foreach -parallel, runspaces or start-job. Example:

$scriptBlock = {
    import-module ADDRS -force
    Login-AzAccount -AccessToken $token.Token -AccountId $token.UserId -Tenant $token.TenantId
    set-vmRightSize -doNotCheckForRecentResize -targetVMName $vm.Name -domain "" -measurePeriodHours $measurePeriodHours -workspaceId $workspace.CustomerId -Verbose -maintenanceWindowStartHour 22 -maintenanceWindowLengthInHours 3 -maintenanceWindowDay 6

Publishing an MSIX as CIM to AVD in a Pipeline

I wanted to put this out there as it felt like a nifty way to pipeline AVD MSIX files into AVD without any user interaction (other than a pipeline kicking off the script).

Basically, above will grab the MSIX file from a known Azure Fileshare (after mounting). It’ll read the MSIX’s primary CIM file for meta data, use the Azure Rest API to add it to the hostpool and then updates a param file of an ARM template which can be used to e.g. update the appgroup in Azure.

You’ll need some background knowledge to re-use above in your specific situation 🙂

Code example:

#create the MSIX package object in the hostpool. Ensure the lastUpdated value is always unique otherwise it will fail to overwrite an existing package with the same value
$apiPostData = @{
    "properties" = @{
        "displayName" = if($packageMeta -match "(?<=<DisplayName>)(.*?)(?=<\/DisplayName>)"){$matches[1]}else{Throw "No display name found in AppManifest"}
        "imagePath" = $imagePath
        "isActive" = $True
        "isRegularRegistration" = $False
        "lastUpdated" = (get-itemproperty $packageFolder.FullName).LastWriteTimeUtc.AddSeconds((Get-Random -Minimum "-150" -Maximum 150)).ToString("yyyy-MM-ddThh:mm:ss")
        "packageApplications" = $packageApplications
        "packageDependencies" = @()
        "packageFamilyName" = "$($packageShortName)_$($packageFamily)"
        "packageName" = $packageShortName
        "packageRelativePath" = "\MSIXPackages\$($packageFolder.Name)"
        "version" = $packageVersion

#send the actual API request to register the package in the hostpool using the pipeline serviceprincipal
    $context = [Microsoft.Azure.Commands.Common.Authentication.Abstractions.AzureRmProfileProvider]::Instance.Profile.DefaultContext
    $token = [Microsoft.Azure.Commands.Common.Authentication.AzureSession]::Instance.AuthenticationFactory.Authenticate($context.Account, $context.Environment, $context.Tenant.Id.ToString(), $null, [Microsoft.Azure.Commands.Common.Authentication.ShowDialog]::Never, $null, "")          
    Invoke-RestMethod -Uri "$((get-azcontext)$($environment)-weeu-01/providers/Microsoft.DesktopVirtualization/hostPools/vdhp-common-$($environment)-weeu-01/msixPackages/$($packageFolder.Name)?api-version=2021-07-12" -Method PUT -UseBasicParsing -ContentType "application/json" -Body ($apiPostData | convertto-json -Depth 15) -Headers @{"Authorization"="Bearer $($token.AccessToken)"} -ErrorAction Stop
    Write-Output $_

Guest report & cleanup new features

My script / runbook to automatically report on stale Guests and clean them up has received some updates

  • Exclusion Groups

Guests in Exclusion groups will never be deleted, even if they are in an Inclusion Group

  • Inclusion Groups

Guests in Inclusion Groups will be deleted if they meet the age requirements, all guests not in an inclusion group will be ignored

  • ReadOnly mode

Will pretend to delete guests are per configured settings, but won’t actually delete anything

Map Onedrive profile Dir to O: at logon

For a basic scenario where users are unwilling or unable to navigate to the Onedrive folder in their profile, the following script will ensure all users on a given machine get their Onedrive profile folder mapped to the O: drive, it auto-installs as scheduled task at logon.

Easily get access token for Azure Management API

Wrote this little snippet that assumes a logged in session (Connect-AzAccount) and easily/quickly produces an auth header.

function get-azRMAccessHeader(){
    $profile = [Microsoft.Azure.Commands.Common.Authentication.Abstractions.AzureRmProfileProvider]::Instance.Profile
    $context = Get-AzContext
    $client = New-Object Microsoft.Azure.Commands.ResourceManager.Common.RMProfileClient($profile)

    $header = @{
        "Authorization" = "Bearer $($client.AcquireAccessToken((Get-AzContext).Tenant.TenantId).AccessToken)"
    return $header
