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.

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.

While a few short-lived DOS based EDuke projects emerged, it was not until the release of EDuke32, an extended version of Duke3D incorporating variants of both Fowler's Microsoft Windows JFDuke3D code and Saettler's EDuke code, by one of 3D Realms ' forum moderators in late 2004 that EDuke's scripting extensions received community focus.

Version 0. 7. 5 also shipped with a new version of the Windows installer.

Opera was somewhat faster, but it was proprietary software distributed in trialware and adware versions, both of which lacked some of the functionality of the Microsoft Windows version.

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.
