Um usuário foi instruído pelo suporte de software a atualizar um programa e instalar o SQLExpress como parte do processo de instalação.
Desde então, o serviço pode iniciar, citando o erro 17053, que parece ser um problema de autenticação.
Aqui está o log de erros:

Um lead que eu tinha era alterar a conta de logon do SQL de "Network Service" para "Local System".
Infelizmente, isso está resultando na mensagem de erro The Security ID Structure is Invalid [0x80070539]
Qualquer ajuda para desinstalar ou executar o SQLExpress seria fantástica.
O primeiro problema é que parece que o banco de dados mestre foi movido ou excluído, ou a pasta teve todos os direitos removidos da conta do SQL Server.
Suponho que você também tenha os direitos para as chaves reg que o SQL Server precisa atualizar bloqueadas.
