1985: Windows 1.0 adds a graphical environment to DOS
Microsoft released Windows 1.0 as a graphical environment running on MS-DOS. Tiled application windows, menus, and mouse input gave personal-computer users an alternative to working entirely through typed commands.

Windows 2.0 added overlapping application windows and expanded keyboard shortcuts. The environment hosted early graphical applications such as Microsoft Excel, strengthening the relationship between application software and the Windows platform.
https://en.wikipedia.org/wiki/Windows_2.01990: Windows 3.0 expands mainstream desktop use
Windows 3.0 introduced Program Manager and File Manager alongside improved memory handling on supported processors. Its broader application ecosystem helped make the graphical Windows environment a central part of the personal-computer market.
https://en.wikipedia.org/wiki/Windows_3.01992: TrueType arrives with Windows 3.1
Windows 3.1 included TrueType font support and improved multimedia capabilities. Scalable fonts made on-screen text and printed output more consistent, helping desktop publishing and everyday document production.
https://en.wikipedia.org/wiki/Windows_3.11993: Windows NT introduces a separate architecture
Microsoft released Windows NT 3.1 with a new operating-system architecture built for protected memory, security, and portability. It ran independently of MS-DOS, establishing the lineage that later underpinned mainstream Windows releases.
https://en.wikipedia.org/wiki/Windows_NT_3.11995: Windows 95 introduces Start and the taskbar
Windows 95 brought the Start menu, taskbar, long filenames, and expanded support for 32-bit applications to consumer desktops. Its architecture still retained dependencies on DOS and older components, unlike the separate Windows NT line.
https://en.wikipedia.org/wiki/Windows_951998: Windows 98 integrates more hardware and web features
Windows 98 expanded support for emerging hardware, including Universal Serial Bus devices, and integrated Internet Explorer more deeply into the desktop. The release continued the consumer Windows line based on the Windows 95 architecture.
https://en.wikipedia.org/wiki/Windows_982000: Windows 2000 strengthens business networking
Windows 2000 extended the NT architecture with features including Active Directory in its server editions. The directory service gave organizations a framework for managing users, computers, and policies across networks.
https://en.wikipedia.org/wiki/Windows_20002001: Windows XP brings NT to consumer desktops
Windows XP combined consumer and professional editions on the NT foundation. Home users gained the architecture’s process isolation and stability benefits while retaining broad compatibility with existing Windows applications.
https://en.wikipedia.org/wiki/Windows_XP2004: XP Service Pack 2 changes default security
Microsoft released Windows XP Service Pack 2 with Windows Firewall enabled by default and a new Security Center. The update treated network exposure and security configuration as core operating-system concerns rather than leaving them entirely to add-on software.
https://en.wikipedia.org/wiki/Windows_XP2007: Vista introduces User Account Control
Windows Vista reached general consumer availability with User Account Control and a redesigned graphics and driver architecture. Asking for elevation before certain administrative actions changed how applications requested privileges and exposed compatibility problems in older software.
https://en.wikipedia.org/wiki/Windows_Vista2009: Windows 7 refines the Vista foundation
Windows 7 retained Vista’s underlying architecture while improving the taskbar, window management, and responsiveness. Features such as window snapping made common desktop arrangements easier, and application and driver compatibility had improved since Vista’s launch.
https://en.wikipedia.org/wiki/Windows_72012: Windows 8 shifts toward touch interaction
Windows 8 introduced a full-screen Start screen and a new application platform with a Windows Store. Microsoft also released Windows RT for Arm devices, whose software restrictions and compatibility differed from the main desktop edition.
https://en.wikipedia.org/wiki/Windows_82013: Windows 8.1 revises desktop navigation
Windows 8.1 restored a visible Start button and added an option to boot directly to the desktop. The update adjusted the relationship between the touch-oriented Start screen and traditional desktop workflows.
https://en.wikipedia.org/wiki/Windows_8.12015: Windows 10 begins a continuing-update model
Microsoft released Windows 10 with a redesigned Start menu, the Edge browser, and virtual desktops. The company moved toward recurring feature updates under the Windows 10 name instead of relying solely on separately branded major releases.
https://en.wikipedia.org/wiki/Windows_102016: Windows gains a Linux compatibility subsystem
The Windows 10 Anniversary Update introduced a beta of Windows Subsystem for Linux. It translated Linux system calls so supported Linux command-line programs could run alongside Windows applications without a conventional Linux virtual machine.
https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux2020: WSL2 ships with a real Linux kernel
Windows 10 version 2004 made Windows Subsystem for Linux 2 generally available. A Linux kernel running in a managed virtual machine replaced system-call translation for the new subsystem, improving compatibility for tools such as containers.
https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux2021: Windows 11 raises hardware requirements
Windows 11 introduced a redesigned interface and requirements including a supported processor and Trusted Platform Module 2.0. The requirements changed which existing computers could officially upgrade, while the operating system retained the NT lineage.
https://en.wikipedia.org/wiki/Windows_112024: Prism expands application emulation on Arm
Windows 11 version 24H2 introduced the Prism emulator for running x86 and x64 applications on Arm-based computers. Emulation helped bridge the gap between a growing native Arm software ecosystem and existing Windows applications.
https://en.wikipedia.org/wiki/Windows_112025: Windows 10 reaches its standard support deadline
Windows 10 version 22H2 reached the end of ordinary support on October 14. Extended Security Updates offered a separate path for eligible devices, while some long-term servicing editions followed different schedules.
