Windows 98 build 1525 from 18 June 1997 is an earlier compile of the official Windows 98 Beta 1 release. It was found on the Dragon C warez compilation CD, which was uploaded onto the Internet Archive on 4 April 2020.[1] It is similar to the aforementioned build except that it contains an older build of Internet Explorer and the Beta 1 string is missing in System Properties.

Changes[edit | edit source]

Windows Setup[edit | edit source]

  • Three icons have been swapped in the setup sidebar.
  • The sidebar explanation for the Emergency Startup Disk stage has been rewritten.
  • During the copying files process, the feature and enhancement showcase section has been updated.
  • During the last part, Setup now has a "System Configuration" section to update system settings. This results in Setup to be longer.
  • The startup sound no longer plays during Windows configuration.
  • Removed Eshell.exe from disc.

Microsoft Family Logon[edit | edit source]

This is the earliest build to include the Microsoft Family Logon client. Compared to later builds, it does not include any graphics, but in terms of functionality, it is already similar to its final iteration.

Other changes[edit | edit source]

  • An updated Beta 1 boot screen has been introduced.
  • Windows now installs Windows Desktop Update by default.
  • The "helpdesk" web app received a redesign.
  • Internet Explorer 4 no longer shows a splash screen.
  • Memphis Release Notes and Memphis Beta Guide documents now mention the OS version as Beta 1.
  • Outlook Express received a slight interface update.
  • Address Book's build number has been updated to 0913.4.
  • This build reintroduces the Quick Launch toolbar by default since build 1415.

Bugs[edit | edit source]

Installation[edit | edit source]

Setup has a WINSETUP.BIN that is not recognized by setup at all times and causes setup to crash on most virtualizers except Microsoft Virtual PC, 86Box, VARCem, and some versions of VMware, due to incorrect emulation of the segment limits of the CPU core. To patch this build to run on any virtualizer, use a WINSETUP.BIN from an earlier build or the RTM.
