Windows 98 SE build 2222A

Windows 98 SE build 2222A is the official RTM build of Windows 98 Second Edition, released on 5 May 1999. Many issues with the first version of the operating system were addressed, including the 49.7-day limit and Y2K-incompliance (the latter of which was already previously fixed in a Y2K update from 1999 alongside the Service Pack 1 update for the original release).

New features include DirectX 6.1a, Internet Connection Sharing, Internet Explorer 5, NetMeeting 3.0, and Windows Media Player 6.1. Minimum system requirements are a 486DX2/66 MHz processor and 24 MB (max 1GB) of RAM.

It is the last version to support upgrade paths from Windows 3.1x.
