History of OS: Genealogy of Windows (From MS-DOS to the Completion of the NT Architecture)

The history of Windows evolution, starting from the CUI-based MS-DOS, transitioning to GUI, and reaching the robust NT architecture.

1. MS-DOS and Windows 1.0 - 3.1

Early Windows was not an independent OS, but merely a GUI shell environment running on MS-DOS. However, the widespread use of Windows 3.1 decisively established the GUI transition for PCs.

2. The Impact of Windows 95

In 1995, Windows 95 was released. The introduction of the Start button and taskbar, along with internet connectivity features included as standard, led to it recording a massive hit worldwide.

    W95 --> WXP["Windows XP"]
    NT --> WXP

3. Integration into the NT Architecture

The 9x kernel for consumers was unstable, whereas the business-oriented Windows NT was robust. In 2001, with “Windows XP”, both were finally integrated into the NT kernel.

4. Windows 10/11 and the Present

Currently, it continues to evolve as Windows as a Service, changing significantly into a developer-friendly environment by incorporating WSL (Windows Subsystem for Linux), among other features.
