We have reviewed group policies, restored domain and domain controller policy to default.

We started googling it and found lists of questions and feedbacks, which were very similar to our issue (Windows 10 joins into a domain and loses a functional Start menu), but we didn’t find any relevant solution among those lists, that would resolve our issue. Meanwhile, if we log in with local account everything works just fine. After we applied our group policies and logged in with domain accounts, part of Windows 10 GUI features, such as Start Menu, Search, Cortana, was inactive. We needed to implement the security policy in a domain, consisted of approximately fifty Windows 10 machines and Windows 2016 Server as a domain controller. We will try to describe how it all started, below. Recently our security team discovered several issues with Windows 10 (Enterprise and Education versions) in Active Directory domain.
