Global Celebrations and Upgrade Experiences for Windows Fans

We will celebrate the unprecedented role our biggest fans – more than 5 million Windows Insiders – played in the development of Windows 10 at special events in 13 cities around the world, including Sydney, Tokyo, Singapore, Beijing, New Delhi, Dubai, Nairobi, Berlin, Johannesburg, Madrid, London, Sao Paolo, and New York City. These celebrations will offer hands-on opportunities, experiential demos, entertainment and opportunities to meet the Windows team.

Microsoft Stores will celebrate the launch of Windows 10 in more than 110 stores in the U.S., Canada and Puerto Rico. In select Microsoft Stores, fan celebrations will feature Windows 10 pop-up demo experiences, prizes, giveaways and more. Answer Desk services and free in-store workshops will help people learn how to get the most out of Windows 10.
