Microsoft Store was a chain of retail stores and is 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 offered Windows (most retail versions), Microsoft Office, and Xbox One game consoles, games, and services including on-site Xbox diagnostics. The Answers Desk helped to answer questions related to Office, Windows, and other Microsoft products; the stores also offer class sessions as well as individual appointments.
