@Crod-8019 Thanks for reaching out! To identify orphaned or unattached mentioned resources, there is no direct way to do. Here are some PowerShell scripts to get the list of unattached mentioned resources.

Below are the commands to install the ‘AZ’ modules in PowerShell:

 Install-Module -Name Az -AllowClobber -Force
 Find-Module -Name Az -Repository PSGallery | Install-Module -Verbose -Force
 set-executionpolicy unrestricted
 Import-Module -Name Az
 Get-InstalledModule -Name Az -AllVersions | select Name,Version

PowerShell commands to find unattached Azure managed disk:

 Connect-Azaccount
 Get-Azsubscription
 Select-Azsubscrciption -Subscription "Subscription Name"
 # Set deleteUnattachedDisks=1 if you want to delete unattached Managed Disks
 # Set deleteUnattachedDisks=0 if you want to see the Id of the unattached Managed Disks
 $deleteUnattachedDisks=0
 $managedDisks = Get-AzDisk
 foreach ($md in $managedDisks) {
     # ManagedBy property stores the Id of the VM to which Managed Disk is attached to
     # If ManagedBy property is $null then it means that the Managed Disk is not attached to a VM
     if($md.ManagedBy -eq $null){
         if($deleteUnattachedDisks -eq 1){
            Write-Host "Deleting unattached Managed Disk with Id: $($md.Id)"
             $md | Remove-AzDisk -Force
             Write-Host "Deleted unattached Managed Disk with Id: $($md.Id) "
         }else{
             $md.Id
         }
     }
 }

 # Set deleteUnattachedVHDs=1 if you want to delete unattached VHDs
 # Set deleteUnattachedVHDs=0 if you want to see the Uri of the unattached VHDs

     $storageKey = (Get-AzStorageAccountKey -ResourceGroupName $storageAccount.ResourceGroupName -Name $storageAccount.StorageAccountName)[0].Value
     $context = New-AzStorageContext -StorageAccountName $storageAccount.StorageAccountName -StorageAccountKey $storageKey
     $containers = Get-AzStorageContainer -Context $context
     foreach($container in $containers){
         $blobs = Get-AzStorageBlob -Container $container.Name -Context $context
         #Fetch all the Page blobs with extension .vhd as only Page blobs can be attached as disk to Azure VMs
         $blobs | Where-Object {$_.BlobType -eq 'PageBlob' -and $_.Name.EndsWith('.vhd')} | ForEach-Object {
             #If a Page blob is not attached as disk then LeaseStatus will be unlocked
             if($_.ICloudBlob.Properties.LeaseStatus -eq 'Unlocked'){
                     if($deleteUnattachedVHDs -eq 1){
                         Write-Host "Deleting unattached VHD with Uri: $($_.ICloudBlob.Uri.AbsoluteUri)"
                         $_ | Remove-AzStorageBlob -Force
                         Write-Host "Deleted unattached VHD with Uri: $($_.ICloudBlob.Uri.AbsoluteUri)"
