Windows 7 is a Microsoft client operating system released to the public on 22 October 2009. It followed Windows Vista and was later replaced by Windows 8.
The system became popular because it kept many of Vista's technical changes while improving performance, compatibility and the general desktop experience. It was used heavily by home users, businesses, schools and public bodies.
Release
Windows 7 was developed after the poor reception of Windows Vista. Vista introduced important security and driver changes, but many users experienced slow performance, driver problems and compatibility issues during its early life.
Windows 7 kept the Windows NT architecture but focused on polish, speed and reliability. It was sold in several editions, including Home Premium, Professional, Enterprise and Ultimate.
Main Features
Windows 7 refined the desktop rather than replacing it. Its main visible changes included a redesigned taskbar, better window snapping, improved search, jump lists, libraries, HomeGroup networking and a cleaner notification area.
The operating system also improved support for newer hardware, multi-touch input, power management, wireless networking and device handling. For many users, the main appeal was that it felt familiar while running better than Vista on the same class of machine.
Use in Businesses
Businesses adopted Windows 7 widely because it was stable, familiar and compatible with a large amount of existing software. Many organisations used it as the direct successor to Windows XP after XP support ended.
Windows 7 Professional and Enterprise were especially common in offices, schools, hospitals, factories and government environments. Those deployments often depended on old line-of-business software, specialist drivers or hardware that was expensive to replace.
End of Support
Microsoft ended mainstream support for Windows 7 on 13 January 2015 and extended support on 14 January 2020. After that point, ordinary Windows 7 systems stopped receiving routine security updates from Microsoft.
Some organisations paid for Extended Security Updates after the normal support period. That did not make Windows 7 a current operating system for general use. It only gave certain customers more time to move away from old systems.
Legacy
Windows 7 is remembered as one of Microsoft's better-received desktop releases. It repaired much of the damage caused by Vista's launch and remained popular even after Windows 8 and Windows 10 were available.
Its long afterlife also created security problems. Unsupported Windows 7 devices can still run, but they are more exposed to unpatched vulnerabilities, unsupported browsers, unsupported drivers and software that no longer receives updates.
