Microsoft is hosting the launch of Windows 10 among 13 Cities around the world including - Sydney, Tokyo, Beijing, New Delhi, Singapore, Dubai, New York, London, Sao Paulo, Madrid, Nairobi, Berlin and Johannesburg.

For the first Time Company is all set to Launch the Mega Event in India. The Event is titled as 'Do Great Things' with a message 'I DO' seen in Windows 10 Promotions. It will be held at Pragati Maidan an Exhibition area in New Delhi on July 29, 2015 4PM onwards. 

The Event is an Invite-Only Event i.e a person would probably get an Invite Request from the Company side and than only he/she could attend the Event.

Microsoft hasn't announced that how many of the 'fans' would be invited to the event but we can assume that if a person is a member of 'Windows Insider Community' and lives nearby among the 13 Cities then he/she has a chance to receive "The Request".
