Windows 98 SE:

Windows 98 (codenamed Memphis) is a graphical operating system released on 25 June 1998 by Microsoft and the successor to Windows 95. Like its predecessor, it is a hybrid 16-bit/32-bit monolithic product based on MS-DOS. Windows 98 was succeeded by Windows Me on 14 September 2000.

New driver standards

Windows 98 was the first operating system to use the Windows Driver Model (WDM). This fact was not well published when Windows 98 was released and most hardware producers continued to develop drivers for the older driver standard, VxD^{[citation needed]}. This resulted in the misconception that Windows 98 can use only VxD drivers. The WDM standard spread years after its release, mostly through Windows 2000 and Windows XP, because these systems are not compatible with the older VxD standard. Today, even if hardware producers are not developing drivers optimized for Windows 98, the drivers written to WDM standards are compatible with Windows 98–based systems.

System requirements

Like its predecessor, Windows 95, and its successor, Windows Millennium Edition (Me), users can bypass hardware requirement checks with the undocumented /nm setup switch. This allows installation on computers with processors as old as the 80386.

Press demonstration

The release of Windows 98 was preceded by a notable press demonstration at Comdex in April 1998. Microsoft CEO Bill Gates was highlighting the operating system's ease of use and enhanced support for Plug and Play (PnP). However, when presentation assistant Chris Capossela plugged a scanner in and attempted to install it, the operating system crashed, displaying a Blue Screen of Death.^[5] Gates remarked after applause and cheering from the audience, "That must be why we're not shipping Windows 98 yet." Video footage of this event became a popular Internet phenomenon.

Windows 98 Second Edition

Windows 98 Second Edition (often shortened to SE) is an updated release of Windows 98, released on 5 May 1999. It includes fixes for many minor issues, improved USB support, and the replacement of Internet Explorer 4.0 with the significantly faster and lighter Internet Explorer 5.0. Also included is Internet Connection Sharing, which allows multiple computers on a LAN to share a single Internet connection through Network Address Translation. Other features in the update include Microsoft NetMeeting 3.0 and integrated support for DVD-ROM drives. A memory overflow issue was resolved which in the older version of Windows 98 would crash most systems if left running for 48 hours. Also included on the CD-ROM is the option to install Microsoft Plus! themes for Windows 98. A list of all features new to Windows 98 Second Edition can be found here. Windows 98SE can be obtained as retail upgrade and full version packages, as well as OEM and a Second Edition Updates Disc for existing Windows 98 users.

Windows 98 System tools

Editions

Modernizing and Expanding

Windows 98 SE can be upgraded with all versions of DirectX up to and including 9.0c. Users can also utilize current bimonthly DirectX SDK updates as long as they are installed over top of a previous DirectX 9.0 "full" release supporting Windows 98. Microsoft .NET Framework up to and including version 2.0 is supported, however versions 2.0 SP1, 3.x, and greater are not. Windows 98 supports MDAC version 2.8. Internet Explorer can be updated to version 6.0 (6.00.2800.1106 Service Pack 1), the same version included with Windows XP SP1 (and the last version available for versions of Windows prior to XP), but it cannot receive current Internet Explorer security updates. Windows 98 can handle the Visual C++ 2005 library and L2TP/IPSec VPN client by Microsoft as well as versions of the Microsoft Installer (MSIA) services up to 2.0. Windows Media Player 9.0 is also supported and can be installed without problems. Due to incompatibilities with the Cairo interface used in version 1.9 of the Gecko Layout Engine, versions of Mozilla Firefox, starting with the 3.0 release, will no longer support Windows 98 or Windows Me,^[6] but all versions of the Opera (web browser) up to and including the latest 9.5 beta release continue to function. There is also a project to provide a compatibility layer which allows the functioning of software requiring Windows 2000 and above.^[7]

Support for more than 512M RAM is achieved with a 3rd party patch or by modifying system.ini.

Internal hard disk support is increased above 137G with any of 3 3rd party patches supporting upto 2TB.

Product life cycle

Microsoft planned to discontinue its support for Windows 98 on 16 January 2004. However, due to the continued popularity of the operating system (27% of Google's pageviews were on Windows 98 systems during October-November, 2003),^[8] Microsoft decided to maintain support until 11 July 2006. Support for Windows Me also ended on this date.^[9] By that time, Windows 98 market share had diminished to 2.7%.^[10]
