Microsoft was founded in 1975 by Bill Gates and Paul Allen. They released the first version of Microsoft Windows in 1985 to compete with Apple's graphical user interface. Over the decades, Microsoft launched many new versions of Windows to take advantage of advancing hardware and software capabilities. Some key versions included Windows 95, which helped popularize the internet, and Windows XP, the most widely used operating system at the time. More recently, versions like Windows 7 improved the user experience with new features, and Windows 8 brought touch capabilities and the Windows Store app marketplace.
