An HP OneAgent update for Windows 11 inadvertently deleted Microsoft Entra ID certificates on some AI PCs, causing users to lose access to their cloud environments. The issue was traced to a cleanup script in the update that mistakenly targeted and removed the necessary certificates. The bug affected a subset of users whose certificates contained the substring "1E", leading to disconnection from Entra ID and authentication failures. HP has since pulled the update and is assisting impacted customers. The impacted devices require a manual recovery process to rejoin the domain.
