Editions and licensing notes

• OEMRET implies images intended for OEM preinstallations and retail licensing—verify activation requirements (OEM keys, volume licensing, or retail product keys).
• Editions (typical): Standard, Datacenter, and possibly Essentials — check licensing documentation for feature differences and virtualization rights.
• Ensure you follow licensing terms for physical vs. virtual deployments and core/socket licensing where applicable.

Deployment guidance

1. Validate hardware/VM compatibility and firmware settings (UEFI, Secure Boot).
2. Obtain correct media and license key for OEMRET build.
3. Backup existing systems and export configurations.
4. Perform a test deployment in staging environment; verify AD, DNS, DHCP, storage, and backup integrations.
5. Apply latest drivers and firmware before production rollout.
6. Harden post-install: apply latest cumulative updates, configure Windows Firewall, enable BitLocker where applicable, and enforce least-privilege administration.
7. Enable monitoring and alerting (Event Forwarding, WAC, or third‑party tools).
