Version 2.1: Bugfix
Version 2.0: Bugfix
Version 1.9: Bugfix
Version 1.8: Streamlined all logic with found Intune/AAD devices, changed output of found objects to a table
Version 1.7: Fixed a situation where there can be multiple Intune devices
Version 1.6: Added assigned user and tag - we will capture the old values, and will allow to change those if needed
Version 1.5: Some change in language around on-prem domain. Added wait for sync if it was less then 10 minutes ago. Fixed a bug when there is no AP devices, but we still want to delete Intune/AAD/AD devices.
Version 1.2: Added more documentation and set of required rights. Now if the device is not found in Autopilot, but exists in Intune (by serial number), it still cleans it from AD DS and AAD
Version 1.1: Invoke-AutopilotSync, when called too soon, error out
Version 1.0: Original public version.

.SYNOPSIS
Interactive script that helps to provision Autopilot machines. Identifies and fixes issues by removing the computer from Intune, AAD, AD and Autopilot, then adds it.

.DESCRIPTION
Runs from OOBE screen, connects to Azure AD, Intune and optionally to AD DS, finds all objects for the serial number of the machine it is running on, then deletes it from everywhere, then adds it to Autopilot again.
Asks for deletion of each object
 Usage:
 - The script can work from running Windows 10, but be careful removing native Azure AD joined Intune Devices - you can lock yourself out, if you do not know local administrator's password
 - Intended usage – from OOBE (Out of Box Experience)
 - While in OOBE, hits Shift+F10
 - Powershell.exe
 - Install-Script AutopilotNuke
 - Accept all prompts
 - & 'C:\Program Files\WindowsPowerShell\Scripts\AutopilotNuke.ps1'
 - The script will:
        Download and install all required modules (accept all prompts)
        Show you the Serial Number of the machine
        Prompt to connect you to Azure AD and Intune Graph
        Ask you if you want to connect to local AD (ADDS, NT Domain) so it could delete old records from there. Enter the local FQDN (domain.com, contoso.local) of your AD Domain
        If you entered local AD domain, it will ask you for the username and password, for the username, use <NetbiosName>\User format
        Search in Autopilot for the serial number
        Show you all objects in Intune and AAD related to that Serial Number
        Ask if you want to delete in from Intune then deletes
        Ask if you want to delete in from Autopilot then deletes
        Loop through all AAD and AD (if it was selected) objects and ask to delete them
        Ask if you want to add it to AP then adds
 
Minimum security rights needed:
• To authorize Intune Graph, you will need global admin, but this is just one time. Ask your GA to run:
    Install-PackageProvider -Name NuGet
    Install-Module AzureAD
     Install-Module WindowsAutopilotIntune
    Install-Module Microsoft.Graph.Intune
    Connect-AzureAD
    Connect-MSGraph
    Accept the consent prompt
• Custom role with the following permissions required in Intune:
    Managed devices
        Read
        Delete
        Update
        Enrollment programs
        Create device
        Delete device
        Read device
        Sync device
    Assigned to All Devices (did not try scoping it with RBAC, but should work in theory)
• Cloud device administrator role required in Azure AD
• AD DS rights similar to Intune Connector rights: https://docs.microsoft.com/en-us/mem/autopilot/windows-autopilot-hybrid#:~:text=The%20Intune%20Connector%20for%20your,the%20rights%20to%20create%20computers.
