How to Check Windows 11 Activation Status and License Channel Using slmgr

While the Windows 11 Settings application displays a simple confirmation stating whether Windows is activated, it provides little technical information regarding your underlying license. The Settings app does not disclose whether your license is an OEM board-locked key, a transferable Retail license, or a temporary volume license managed by an organisation’s Key Management Service (KMS). Using the Software Licensing Management Tool (slmgr.vbs), you can inspect deep licensing attributes, verify genuine permanent activation, and check license expiration timers.

Checking Basic Activation and License Channel with /dli

The /dli (Display License Information) parameter displays your Windows edition, partial product key, and license channel.

1. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
2. In the terminal window, type the following command and press Enter:

   slmgr /dli

3. A Windows Script Host dialogue box will appear on your desktop.

Review the Description line in the dialogue box:

• RETAIL channel: Indicates a full retail copy purchased independently. This license is legally transferable to another motherboard or PC build if you decommission the original machine.
• OEM_DM channel: Indicates an Original Equipment Manufacturer license embedded in the motherboard UEFI firmware by vendors like Dell, HP, or Lenovo. OEM licenses are permanently tied to the original hardware and cannot be transferred.
• VOLUME_KMS / VOLUME_MAK: Indicates a corporate or educational enterprise license that requires periodic renewal against an organisational activation server.

Verifying Permanent Activation vs Expiration with /xpr

Third-party license activators and corporate KMS keys often report “Activated” in the Settings app even though the license is set to expire within 30 to 180 days. To verify whether your operating system is activated permanently:

slmgr /xpr

Executing this command produces a clear popup window stating either:

• “The machine is permanently activated.” — Your Windows 11 installation possesses a genuine, indefinite digital license.
• “Volume activation will expire [Date/Time]” — The installation relies on a temporary lease that will revert to an unactivated state unless renewed.

Extracting Detailed Licensing Diagnostics with /dlv

For advanced auditing, troubleshooting activation error codes, or inspecting KMS server hostnames, the /dlv (Display Detailed License Information) parameter provides comprehensive cryptographic licensing data:

slmgr /dlv

This comprehensive view displays your unique Activation ID, Application ID, extended PID, remaining Windows rearm count, and trusted time-stamping details.
