Windows Activation FAQ


Windows Licensing Terms

Duke’s Microsoft agreement allows volume-licensed Windows installations on Duke-owned devices for university use. Personal retail versions of Windows are not available through Duke’s licensing program. For full terms, visit the Windows License Restrictions page.


Windows for Students

Duke students may request one free upgrade license of Windows via the Duke Software site. This license is activated with a product key and remains valid after graduation. Students may not request multiple licenses.


KMS and MAK Activation

KMS Activation

Duke-managed Windows installations use Key Management Service (KMS) for activation. Devices on the Duke network (or connected via VPN) should activate automatically.

  • Activation is valid for 180 days.
  • Systems auto-renew every 7 days while on the Duke network.
  • Devices offline for 180+ days enter a grace period and then reduced functionality mode.

MAK Activation

For Duke-owned machines regularly used off-campus, request a MAK (Multiple Activation Key).

Email site@duke.edu to request a MAK key. Requests are reviewed by OIT case-by-case. MAK keys are not available for graduated or departing students.


Manual Activation Steps

  1. Ensure the computer is on the Duke network or connected via VPN.
  2. Right-click Start and select Command Prompt (Admin) or Windows Terminal (Admin).
  3. Run the following commands one at a time:
  • slmgr /skms kms-srv-01.oit.duke.edu
  • slmgr /ato

To confirm activation, run:

  • slmgr /dlv

Activating Off-Campus Using VPN

If you are off-campus, use Duke's VPN before activating Windows. Once connected, follow the manual activation steps above. VPN instructions can be found on the OIT VPN page.


Home Use for Faculty & Staff

Faculty and staff may install volume-licensed Windows on a home computer for work purposes only. Installation must be performed by your department IT staff or with their written permission. Duke does not provide personal retail Windows licenses for home use.
