Please note that you need to be either on campus or on the VPN to activate. You may use either the UMIACS or the campus VPN. This tutorial also assumes you have already have a network connection established.

Windows Licensing

Windows 7/8/10 use an activation model for each install. The installs will have to verify activation every 180 days. Activation and renewal is performed via the campus Key Management Server KMS, which is not available from off campus. For onsite desktops, this is not a problem. However, for laptops it poses a potentially serious complication. As long as the laptop is periodically on the campus wireless or connects to the UMIACS or campus VPN, renewal activation will be performed automatically.


Please note that your time must be correct for this to work, make sure you are in the East Coast timezone and your time is set via the internet, try running "w32tm /resync" on the command line.

  1. Click the Windows button and type "cmd" in the run bar.

  5. From the Command Prompt, run these commands in order, replacing the key in line 2 with the appropriate key:
    cscript c:\windows\system32\slmgr.vbs -skms
    cscript c:\windows\system32\slmgr.vbs -ipk <insert key here>
    cscript c:\windows\system32\slmgr.vbs -ato
    • Common keys:
      • Windows 7 Enterprise - 33PXH-7Y6KF-2VJC9-XBBR8-HVTHH
      • Windows 8.1 Enterprise - MHF9N-XY6XB-WVXMC-BTDCT-MKKG7
      • Windows 10 Enterprise - NPPR9-FWDCX-D2C8J-H872K-2YT43

After these commands have run, the Key Management Server should have activated your Windows computer.

If you are unable to activate, please see the message at the top of this page and contact UMIACS staff with information about your problem.
