Difference between SNGL and GGWA license

Hi! Azim. I'm here to help.

You're asking about the difference between two Microsoft licensing terms:

Windows GGWA – Windows 11 Pro – Legalization (Get Genuine)

WinPro 11 SNGL OLP NL Legalization GetGenuine

Here’s what they each refer to and how they compare:

GGWA (Get Genuine Windows Agreement – e.g., Windows 11 Pro Legalization)

Purpose: Legalizes non-genuine or mis-licensed Windows installs.

License: Perpetual, full Windows Pro license.

Requirements: No qualifying OS needed (can fix pirated, unlicensed, or improperly upgraded systems).

Transfer: Tied to device hardware, not transferable.

Use case: Retroactive compliance only, not for new deployments.

Channel: Usually sold via CSP/resellers.

WinPro 11 SNGL OLP NL Legalization GetGenuine

• Purpose: Same as GGWA → legalization license.
• License structure:
  • SNGL = single license,
  • OLP = Open License Program (volume licensing for SMBs),
  • NL = “No Level” (no volume discount tier).
• Still a perpetual, device-based license used for legalizing installs.
• Delivered under the OLP (volume licensing) framework instead of CSP.

Both legalize existing Windows installs, both tied to hardware, both perpetual.

Main difference = licensing channel:

GGWA → general/CSP route.

SNGL OLP NL GetGenuine → packaged for SMBs under Open License Program.
