6. Considerações sobre licença OEM ESD

  • Vinculada à máquina onde é ativada (ligada ao hardware).
  • Suporte e transferência: normalmente não transferível entre máquinas (política OEM).
  • Suporte técnico: responsabilidade do fabricante/fornecedor OEM.
  • Validade: licença perpétua para aquela versão; atualizações de recursos futuras dependem do suporte da Microsoft para o build.

ESD

Electronic Software Distribution. A highly compressed, encrypted file format used by Microsoft for online downloads and updates. Compared to a WIM file, ESD is 30-40% smaller. However, it requires conversion or proper deployment tools (DISM) to use. The Ghost in the ISO: Examining "Windows 10

2.1 Core Architecture: x64

The designation "X64" refers to the 64-bit architecture (AMD64/Intel 64). This architecture allows the operating system to utilize more than 4 GB of RAM, a standard requirement for modern professional workstations. Unlike the x86 (32-bit) counterpart, the x64 build of Windows 10 21H1 includes enhanced security features dependent on processor capabilities, such as Kernel Patch Protection (PatchGuard) and mandatory hardware-level Data Execution Prevention (DEP).

7. Processo de implantação (passos recomendados)

  1. Verificar compatibilidade de hardware e firmware (UEFI/TPM).
  2. Backup completo dos dados e criação de mídia de recuperação.
  3. Criar mídia de instalação ESD convertida para ISO (se necessário).
  4. Criar imagem de referência com atualizações cumulativas e drivers essenciais.
  5. Testar ativação com chave OEM em máquina de referência.
  6. Implantar via MDT/SCCM/Intune com scripts de configuração (driver, idiomas, chaves).
  7. Validar pós-instalação: ativação, drivers, políticas de segurança, Windows Update.
