Windows 9x is a group of operating systems that constitute the fourth iteration of the Windows product line by Microsoft.

It is a hybrid 16-bit and 32-bit OS. The boot stage is based on MS-DOS.


The Windows 9x series featured a new streamlined GUI, with a taskbar, a start menu to quickly load applications, and a recycling bin icon and associated app that would hold files to be deleted and would delete them from the computer upon emptying the recycle bin.

Windows NT 4.0 introduced the Windows 9x interface to the Windows NT line.


Windows 95 and its OEM Service Releases, Windows NT 4.0, Windows 98, Windows 98 Second Edition, and Windows Millenium Edition relied on DOS but had a 32-bit protected mode driver instead of the standard 16-bit driver to allow for 32-bit disk access.

The Windows 9x series ran DOS programs through a DOS-based Virtual DOS Machine. 16-bit Windows applications were run through a compatibility layer known as Windows on Windows.
