Microsoft Store is a chain of retail stores and an online shopping site, owned and operated by Microsoft and dealing in computers, computer software, and consumer electronics. The Microsoft Store offers Signature PCs and tablets like the Microsoft Surface, and offerings from third parties such as Acer, Dell, HP, Lenovo, and VAIO without demos nor trialware (pre-installed free trials of certain third-party software that expire after a limited time). It also offers Windows (most retail versions), Microsoft Office, and Xbox One game consoles, games, and services including on-site Xbox diagnostics. The Answers Desk helps to answer questions related to Office, Windows, and other Microsoft products;the stores also offer class sessions as well as individual appointments. The first two Microsoft Stores opened within a week of the Windows 7 launch, in Scottsdale, Arizona and Mission Viejo, California. Additional stores have since opened in California, Colorado, Florida, Georgia, Illinois, Minnesota, Missouri, Texas, and Washington. At the 2011 Professional Developers Conference, Microsoft announced that they intend to open 75 new stores in the next three years. The first store outside the U.S. (and the first of eight stores in Canada) opened in Toronto on November 16, 2012, while the first store outside North America (and first store in Asia-Pacific and second flagship store) opened in Sydney, Australia on November 12, 2015. In September 2017, the company announced a store on Regent Street in London, England.
