Windows 98 Upgrade Retail Packaging Options

When Microsoft released Windows 98 in June 1998, followed by Windows 98 Second Edition (SE) in 1999, consumers transitioning from earlier operating systems had several distinct retail upgrade packaging options. This overview covers the physical retail configurations offered to consumers, detailing the media formats, box variations, and specific upgrade paths Microsoft made available during the operating system's retail lifecycle.

Windows 98 First Edition Upgrade (CD-ROM)

The primary retail package was the standard Windows 98 Upgrade edition on CD-ROM. Designed for users migrating from Windows 3.1 or Windows 95, this version arrived in a full-sized retail carton featuring Microsoft's late-1990s signature curved or beveled box styling. Inside, buyers received the installation CD-ROM housed in a jewel case, a printed "Getting Started" user manual, and a Certificate of Authenticity (COA) featuring the 25-character product key.

Windows 98 First Edition Upgrade (3.5-Inch Diskettes)

For users with older systems lacking a CD-ROM drive, Microsoft offered an upgrade SKU on 3.5-inch high-density floppy disks. Because Windows 98 was substantial in size, this package contained dozens of diskettes compressed using Microsoft's Distribution Media Format (DMF). While primarily acquired through direct mail-in fulfillment coupons included in select retail boxes, standalone retail-packaged floppy sets were distributed in limited quantities in certain markets.

Windows 98 Second Edition Upgrade (Full Retail Box)

Following the release of Windows 98 SE in 1999, Microsoft issued an updated retail upgrade box. Marketed with prominent red and blue "Second Edition" branding, this package allowed users running Windows 3.1 or Windows 95 to upgrade straight to Windows 98 SE on CD-ROM. It included the full operating system installation files along with Internet Explorer 5.0 and updated hardware drivers.

Windows 98 Second Edition "Updates" Packaging

To accommodate users who had already purchased the original release of Windows 98, Microsoft produced the Windows 98 Second Edition Updates package. Sold at a significantly reduced price point, this version came in a slimmer, cost-effective retail box or jewel-case sleeve. It contained an update CD-ROM designed strictly to apply the SE enhancements over an existing, valid Windows 98 First Edition installation.
