Windows Server 2012

Windows Server 2012 is a legacy platform. Microsoft ended support for it on 10 October 2023, so it no longer receives regular security updates. We keep a genuine key in stock for organisations that must run an application certified only for 2012, and we recommend Windows Server 2022 or 2019 for everything else. It is part of our Windows Server range.

• Windows Server 2012 Standard key
• For legacy application compatibility
• Modern alternatives: Server 2022 and 2019
• Email delivery and activation guide
• 10-day replacement guarantee

• Choose Server 2012 only when a specific application, driver or compliance process still requires it: Windows Server 2012 Standard.
• Choose a current release for anything new — Server 2022 Standard or Server 2019 Standard — to keep receiving security updates.

Read Windows Server editions explained to compare editions.

• A genuine product key delivered by email delivery (usually within minutes, always within 24 hours of payment).
• Activation instructions and our 10-day replacement guarantee.
• Support from our team for installation questions.

Without Microsoft updates, keep a 2012 server isolated: restrict internet exposure, segment the network, keep backups and plan a migration. Only Microsoft's paid Extended Security Updates programme covers it. For a migration path, start with Windows Server 2022.

1. Install the edition that matches your key.
2. Open an elevated Command Prompt and run slmgr /ipk <key>, then slmgr /ato.
3. Verify with slmgr /dli.
