Overview

Microsoft Windows has gone through many versions since 1985. This guide lays out the major releases in order, what each introduced, and how to check which version you are running.

Windows has evolved from version 1.0 to Windows 11.

Key Takeaways

  • Windows began in 1985 with version 1.0.
  • The NT line (from Windows NT/2000/XP) became the modern Windows foundation.
  • Windows 10 and 11 are the current consumer releases.
  • Run winver to see your exact version and build.

Early Windows (1985–2000)

  • Windows 1.0 (1985) and 2.0 (1987) — the first graphical shells over MS-DOS.
  • Windows 3.0/3.1 (1990–92) — popularized Windows with a better UI and apps.
  • Windows 95 (1995) — Start menu, taskbar, and 32-bit apps.
  • Windows 98 / Me (1998–2000) — consumer updates building on 95.

The NT Line (1993–2009)

  • Windows NT 3.1–4.0 (1993–96) — the business/enterprise kernel that underpins modern Windows.
  • Windows 2000 (2000) — NT-based, introduced Active Directory.
  • Windows XP (2001) — merged consumer and NT lines; hugely popular and long-lived.
  • Windows Vista (2007) and 7 (2009) — new UI (Aero); Windows 7 was widely loved.

Modern Windows (2012–Present)

  • Windows 8 / 8.1 (2012–13) — touch-focused Start screen (controversial).
  • Windows 10 (2015) — returned the Start menu; delivered as "Windows as a service" with feature updates.
  • Windows 11 (2021) — redesigned UI, stricter hardware requirements (TPM 2.0), and ongoing annual updates (22H2, 23H2, 24H2, 25H2).
