Reactivate Windows 10 License (TC Computers)

If you receive the "Your Windows License will expire soon" prompt, you must first connect to the Teachers College network either by wired or wireless connection on campus, or using VPN remotely before proceeding below.

Using Windows Search, type in CMD. When the command prompt appears in the search, open it.

In Command Prompt, type in slmgr.vbs /ato and press the enter key.

A prompt will appear a couple of moments later indicating that Windows has successfully activated.

If you have any issues with activating Windows 10 on your TC labeled computer, please contact the Technology Service Desk by calling (212) 678-3300 or email
