  • The first local user account created during installation of this build would not be placed in the local Administrators group, which prevents any operations that need to be performed with elevated privileges. It can be resolved by booting Windows in safe mode, and changing group membership for the local user account using the Local Users and Groups tool (lusrmgr.msc) in Computer Management.
