Microsoft Windows 98 Second Edition
Windows 98 Second Edition (often shortened to SE) is an updated release of Windows 98, released on May 5, 1999. It includes fixes for many minor issues, improved WDM audio and modem support, improved USB support, the replacement of Internet Explorer 4.0 with Internet Explorer 5.0, Web Folders (WebDAV namespace extension for Windows Explorer), and related shell updates. Also included is basic OHCI-compliant FireWire (IEEE 1394a) DV camcorder support (MSDV class driver) and SBP-2 support for mass storage class devices, Wake-On-LAN support (if ACPI compatible NDIS drivers are present) and 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 DirectX 6.1 which introduced major improvements to DirectSound and the introduction of DirectMusic, improvements to Asynchronous Transfer Mode support (IP/ATM, PPP/ATM and WinSock 2/ATM support), Windows Media Player 6.2 replacing the older Media Player, Microsoft NetMeeting 3.0, MDAC 2.1 and WMI. A memory overflow issue was resolved which in the older version of Windows 98 would crash most systems if left running for 49.7 days (equal to 2³² milliseconds). Windows 98 SE could 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 Second Edition did not ship with the WinG API or RealPlayer 4.0 unlike the original release of Windows 98, both of these being superseded by DirectX and Windows Media Player.
