Windows is the leading desktop operating system, with over 70% of desktops using Windows globally according to StatCounter. As of January 2022, 1.4 billion monthly active devices ran Windows 10 and Windows 11, and the number of devices running Windows 11 more than doubled in 2023.

Browsers are a key enabler of other important services such as AI, and productivity tools, and the browser market has great potential, with direct economic impact. Desktop continues to be an important way for users to access the internet and apps, as well as for developers to be found by users. This is especially true in the important educational and enterprise contexts. However, Microsoft restricts the ability of rival software to compete on Windows by creating onerous restrictions for competitors that frustrate consumer choice.

The Browser Choice Alliance aims to promote genuine competition in the desktop browser market. This will support growth and innovation, for the benefit of consumers and developers alike.
