Edit 01/06/2022 : updating this article to include Azure Virtual Desktop Windows 10 / Windows 11 multi-session enrollment command using Device Credential

——–

There are several ways to enroll a Windows 10 PC to Microsoft Intune:

Manually

• During the Out-of-the-box Experience (OOBE), when starting a Windows 10 PC for the first time
• In the Windows Settings, after the PC configuration

Manual enrollment will require that the user enters his Azure AD credentials.

Automatically

• Using Azure AD Join + automatic Intune enrollment
• Using Hybrid Azure AD Join + automatic Intune enrollment

Automatic enrollment can be triggered using a Group Policy, SCCM Co-Management or Windows AutoPilot.

Windows 10 automatic enrollment requires the creation of public DNS records enterpriseregistration and enterpriseenrollment. More info here.

However, sometimes it is possible that a Windows 10 PC is in an inconsistent enrollment state, with error “The sync could not be initiated“.

This can happen because:

• The PC was shut down during a long time, and the Microsoft Intune certificate is expired (located in Local Machine / Certificates / Personal)
• Someone manually deleted the Microsoft Intune certificate
• The PC is enrolled in another Intune tenant

Prerequisites: check Hybrid Azure AD Join status

Before re-enrolling your device to Microsoft Intune, you need to make sure that the certificates for Hybrid Azure AD Join are not expired as well.

Follow this procedure to Manually re-register a Windows 10 / Windows 11 or Windows Server machine in Hybrid Azure AD Join.

Method 1: With data and configuration loss

The easiest way to unenroll a Windows 10 PC from Microsoft Intune is to disconnect the work or school account.

Just go to All settings > Accounts > Access work or school, select your corporate account and click Disconnect.

Important: this menu is not available on Windows 10 / Windows 11 multi-session edition for Azure Virtual Desktop.

However, the problem with this is that all data and configuration pushed by Microsoft Intune will be deleted from the PC.

Method 2: Without data or configuration loss

There is a way to manually re-enroll your Windows 10 PC without loosing all the current configuration and apps deployed by Microsoft Intune.

This method is not officially supported by Microsoft

As you may know, automatic enrollment can be triggered either by a Group Policy Object or by the SCCM client on a co-managed device.

In both cases, the feature will basically create a scheduled task to enroll the PC at next logon. The command is different if you are trying to enroll Windows 10 / Windows 11 Enterprise multi-session devices from Azure Virtual Desktop (using Device Credential) or a regular Windows 10 / Windows 11 device using User Credential:

Windows 10 / Windows 11 Enterprise (with User Credential)

Task launched in the SYSTEM context:

%windir%\system32\deviceenroller.exe /c /AutoEnrollMDM

Windows 10 / Windows 11 Enterprise Multi-session for Azure Virtual Desktop (with Device Credential)

Task launched in the SYSTEM context:

%windir%\system32\deviceenroller.exe /c /AutoEnrollMDMUsingAADDeviceCredential

To manually re-enroll the PC, we will need to clean up the environment and relaunch this command in the SYSTEM context to re-enroll the PC.

Here are the steps that you need to follow to make it work:

1. Delete stale scheduled tasks
2. Delete stale registry keys
3. Delete the Intune enrollment certificate
4. Restart the enrollment process

Step 1: Delete stale scheduled tasks

Follow this procedure:

• Run the Task Scheduler as an administrator.

• Go to Task Scheduler Library > Microsoft > Windows > EnterpriseMgmt. Write down the enrollment ID somewhere, you will need it for the cleanup.

• Delete all the existing tasks the enrollment folder.

• Delete the enrollment ID folder.

Step 2: delete stale registry keys

Use the previous enrollment ID to search the regitry:

• Open the Registry Editor as an administrator.

• Search for the enrollment ID you wrote in the following locations and if found, delete the key that is containing the ID:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Enrollments\xxxxxxxxxxxxx
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Enrollments\Status\xxxxxxxxxxxxx
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EnterpriseResourceManager\Tracked\xxxxxxxxxxxxx
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\AdmxInstalled\xxxxxxxxxxxxx
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\Providers\xxxxxxxxxxxxx
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Provisioning\OMADM\Accounts\xxxxxxxxxxxxx
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Provisioning\OMADM\Logger\xxxxxxxxxxxxx
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Provisioning\OMADM\Sessions\xxxxxxxxxxxxx

DO NOT delete registry keys that are not in the list above. They will be overwritten after the new enrollment.

Step 3: delete the Intune enrollment certificate

Follow the procedure:

• Search for the option “Manage computer certificates” or use the command certlm.msc as an administrator.

• Go to Personal > Certificates and delete the certificate issued by either “Microsoft Intune MDM Device CA” or “SC_Online_Issuing” (depending on the date of the enrollment).

Step 4: Restart the enrollment process

To be properly executed, the enrollment command must be entered in a SYSTEM context. We will use the PSExec tool for that purpose.

• Download the PSExec tool from Microsoft website

• Use PSExec to launch a Command Prompt as SYSTEM:

psexec /i /s cmd

• In the Command Prompt, enter one of the following command depending on your enrollment type:

Windows 10 / Windows 11 Enterprise (using User Credential)

%windir%\system32\deviceenroller.exe /c /AutoEnrollMDM

Windows 10 / Windows 11 Enterprise Multisession for Azure Virtual Desktop (using User Credential)

%windir%\system32\deviceenroller.exe /c /AutoEnrollMDMUsingAADDeviceCredential

• In the computer certificate store, check that a new Intune certificate has been enrolled for the device:

• You are now ready to start a policy sync from the Windows Settings, and check that the connection with the Intune service is now OK:
