Windows 98 End of Life Support Date

Microsoft officially terminated all support for the Windows 98 operating system on July 11, 2006. This article covers the specific timeline of Windows 98's lifecycle, the extension Microsoft granted past its original retirement date, and what the end-of-life status meant for users and organizations still relying on the legacy operating system.

The Official End-of-Life Date

Microsoft ended extended support for both Windows 98 and Windows 98 Second Edition (SE) on July 11, 2006. On the same date, Microsoft also ended support for Windows Millennium Edition (Windows Me).

The Lifecycle Timeline

• Release Date: June 25, 1998
• Mainstream Support Ended: June 30, 2002
• Original Extended Support Deadline: January 16, 2004
• Final Extended Support Deadline: July 11, 2006

Microsoft originally planned to end support for Windows 98 in January 2004. However, due to the operating system's persistent global popularity, particularly in emerging markets and smaller businesses, Microsoft extended the support window by an additional two and a half years to give customers adequate time to migrate to modern operating systems like Windows XP.

What the End of Support Entailed

Reaching the end-of-life phase meant the complete cessation of updates and assistance from Microsoft:

• No Security Updates: Microsoft stopped developing and distributing security patches, leaving unpatched vulnerabilities permanently open to security threats.
• No Assisted Support: Incident-based technical support, both via phone and online channels, was discontinued.
• No Software Changes: Non-security hotfixes, usability updates, and driver additions ceased completely.
• Online Documentation: Microsoft transitioned support documentation to its online self-help knowledge base, which remained accessible for historical reference until 2007.

The retirement of Windows 98 marked the formal conclusion of the MS-DOS-based Windows 9x line, cementing Microsoft's shift to the modern Windows NT architecture.
