 >Only Windows 10 computers with a specific userCertificate attribute value configured by Hybrid Azure AD Join are supposed to be synced to the cloud by Azure AD Connect.  In previous versions of Azure AD Connect this requirement was not rigorously enforced, resulting in unnecessary device objects in Azure AD. Such devices in Azure AD always stayed in the “pending” state because these computers were not intended to be registered with Azure AD.

->Some customers may see some or all of their Windows devices disappear from Azure AD. This is not a cause for concern, as these device identities are not used by Azure AD during conditional access authorization. Some customers may need to revisit [How To: Plan your hybrid Azure Active Directory join implementation](../../active-directory/devices/hybrid-azuread-join-plan.md) to get their Windows computers registered correctly and ensure that such devices can fully participate in device-based conditional access. If Azure AD Connect is attempting to delete [down-level Windows devices](../../active-directory/devices/hybrid-azuread-join-plan.md#windows-down-level-devices) then the device is not the one that was created by the [Microsoft Workplace Join for non-Windows 10 computers MSI](https://www.microsoft.com/download/details.aspx?id=53554) and it is not able to be consumed by any other Azure AD feature.  Note that if you see the deletes of Computer/Device objects in Azure AD exceeding the Export Deletion Threshold, it is advised that the customer allow these deletes to go through.
