A Hongkonger showcased his expertise in Microsoft Word, beating 144 fellow students to gain first place in the Microsoft Office Specialist World Championship in the United States. Lee Pak-hei, 17, was named world champion in Microsoft Word 2013 (the most recent version of the software) at a ceremony in Dallas, Texas.
He won a scholarship worth US$7,500 in the competition organised by testing firm Certiport.
"These winners are part of an elite group that know how to use Microsoft Word efficiently and to its full potential," said Certiport's Aaron Osmond.
The championship saw 600,000 people from 47 countries aged between 13 and 22 compete to show their skills across Microsoft Office products.
More than 1.2 billion people use Microsoft Office, which includes Word, Excel and PowerPoint.
In the final, contestants completed project-based tests to show their ability to create documents in Word.
China's Yuting Cao came second, followed by Yoko Shimoji from Japan.
"Winning the world championship puts them in a class of their own, and we look forward to seeing how they put their Microsoft Office skills to use in the future," said Alison Cunard, general manager of learning experiences at Microsoft.
Last month, Microsoft launched Windows 10, the latest version of its popular operating system.
The move came as the technology giant's strategy was being questioned by analysts as sales of the Xbox One and Surface tablet family failed to generate big profits, and may even be costing the firm money.
