Windows 98 build 1721.3

Windows 98 build 1721.3 is the official Release Candidate 1 build of Windows 98. It was uploaded to BetaArchive FTP on 6 June 2014 by BetaArchive user marcoguy. The Spanish version of this build was supposedly uploaded to the Chinese website BetaWorld on 18 December 2021, and its full CD (claimed to be RTM) was used as a base for the warez CD "Super 98" which was uploaded to the Internet Archive on 16 December 2021. A CD photo of the Korean version of this build alongside with the CD for Build 1910.2 in Korean have been shown in a BetaArchive thread, and the Simplified Chinese version was shown in a book named "如何使用Windows 98中文版". While the Korean and Simplified Chinese versions of this build remain unleaked. Currently, this build is available only in the English and Spanish languages.

This build was released with the following information from Microsoft to beta testers during the time: Dear Windows 98 Beta Testers,

We have taken the incredibly fast feedback we received on 1720 as well as fixes that were already in the works and we are closer than ever to RC1. We have implemented some core fixes which should help Power Management, Multimedia and Dial-Up Networking. We would like all of you to download this build if possible and give it a thorough run through.

Note: You do not have to download this build to stay active; this is an optional download.

Changes

 * Introduced a new splash screen for the Internet Connection Wizard.
