For example, EDLIN in early MS-DOS versions and 32-bit versions of Windows NT has a somewhat similar syntax, and text editors in many MUDs ( LPMud and descendants, for example ) use ed-like syntax.

However, Edlin is included in 32-bit versions of Windows NT, since NTVDM's DOS support is based on MS-DOS version 5. 0.

FCPLib supports Windows NT / 2K / XP, Debian, BSD, Solaris, and Mac OS X.

The Windows NT family started with Windows NT 3. 1 in 1993.

Modern Windows operating system versions are based on the newer Windows NT kernel that was originally intended for OS / 2.

Microsoft is also working to bring Windows NT onto ARM in the next release of Windows.

With Windows NT 4. 0 in 1996, the shell changed from Program Manager to Windows Explorer.

IBM continued to develop OS / 2, while Microsoft changed the name of its ( as yet unreleased ) OS / 2 3. 0 to Windows NT.

Both retained the rights to use OS / 2 and Windows technology developed up to the termination of the agreement ; Windows NT, however, was to be written anew, mostly independently ( see below ).

1993 saw a release for PCs with Windows 3. 1 as part of the original Microsoft Arcade package.

Operating systems such as Microsoft Windows that display hard drive sizes using the customary binary prefix " GB " ( as it is used for RAM ) would display this as 279. 4 GB ( meaning 279. 4 × 1024 < sup > 3 </ sup >, or 279. 4 ×).

* Microsoft Windows contains application compatibility shims to make the platform compatible with most software from earlier 32-bit and 16-bit versions ( e. g. Civilization ( circa 1991, designed for Windows 3. 0 ) running on Windows Vista ).

Castle of the Winds ( CotW ) is a tile-based roguelike video game for Windows 3. x.

All terrain tiles, some landscape features, all monsters and objects, and some spell / effect graphics take the form of Windows 3. 1 icons.

* A Windows based Tool uses any standard PC 3. 5 " Drive to WRITE & READ 1581 Disk Images.

Device drivers, particularly on Microsoft Windows platforms, can run in kernel-mode ( Ring 0 on x86 CPUs ) or in user-mode ( Ring 3 on x86 CPUs ).

* CNG API in Windows Vista and Windows Server 2008 with managed wrappers for CNG in. NET Framework 3. 5

The perennial debates between users of competing operating systems such as Windows, Mac OS, or the GNU / Linux operating system, users of Intel and AMD processors, and users of the Wii, PlayStation 3 and Xbox 360 video game systems, often escalate into seemingly unending " flamewars ", called also software wars.

Sega also made video games based on Garfield for the Genesis ( Garfield Caught in the Act ) and Windows 3. 1 computers, as well as other companies made games, such as A Tale of Two Kitties for the DS, published by Game Factory, Garfield's Nightmare for DS, Garfield's Funfest for DS, and Garfield Labyrinth for Game Boy.

The 3. x and 4. x family includes Windows 3. 0, Windows 3. 1x, Windows 95, Windows 98, and Windows Me.

Also, a new version of Asteroids was developed for PlayStation, Nintendo 64, Windows, and the Game Boy Color in the late 1990s.

Since Java's bytecode is platform-independent, Java applets can be executed by browsers running under many platforms, including Windows, Unix, Mac OS, and Linux.

* wav – standard audio file container format used mainly in Windows PCs.

* wma – the popular Windows Media Audio format owned by Microsoft.

Microsoft first introduced AGP support into Windows 95 OEM Service Release 2 ( OSR2 version 1111 or 950B ) via the USB SUPPLEMENT to OSR2 patch.

After applying the patch the Windows 95 system became Windows 95 version 4. 00. 950 B.

EFI booting has been supported in only Microsoft Windows versions supporting GPT, the Linux kernel 2. 6. 1 and later, and Mac OS X on Intel-based Macs.

Cygwin 1. 5 represented them as Windows Explorer shortcuts, but this has been changed for reasons of performance and POSIX correctness.

Although most manufacturers of hard disk drives and flash-memory disk devices define 1 gigabyte as, software like Microsoft Windows reports size in gigabytes by dividing the total capacity in bytes by, while still reporting the result with the symbol " GB ".

Support for SNI is available since Firefox 2, Opera 8, Safari 2. 1, Google Chrome 6, and Internet Explorer 7 on Windows Vista.

The first independent version of Microsoft Windows, version 1. 0, released on 20 November 1985, achieved little popularity.

Windows 1. 0 was not a complete operating system, but rather an " operating environment " that extended MS-DOS, and shared the latter's inherent flaws and problems.

In the development of Windows 1. 0, Microsoft intentionally limited its borrowing of certain GUI elements from the Macintosh user interface, to comply with its license.

Later, two new versions were released: Windows / 286 2. 1 and Windows / 386 2. 1.

Like prior versions of Windows, Windows / 286 2. 1 used the real-mode memory model, but was the first version to support the High Memory Area.

Windows / 386 2. 1 had a protected mode kernel with LIM-standard EMS emulation, the predecessor to XMS which would finally change the topology of IBM PC computing.

A " multimedia " version, Windows 3. 0 with Multimedia Extensions 1. 0, was released in October 1991.
