Windows 98 build 1721.3

Windows 98 build 1721.3 is an RC1 build of Windows 98. This build was scene leaked in 1998, but had been lost for many years. On 6 July 2014, marcoguy shared this build again with the beta collecting community. It introduces a new splash screen for Internet Connection Wizard.

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 recieved 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.
