Windows 98 build 1593 is a Beta 2/2.1/3 build of Windows 98. This is the last build to have Windows 95 startup, shutdown, and error sounds before being replaced in build 1602 with the RTM sounds from Windows 98 except for the Tada and shutdown sounds. This build was scene leaked by a warez group in late September 1997.

New features and changes[edit | edit source]

  • The "Welcome To Windows 98" application is completely different from the versions found in 1588 and earlier. It features the Windows 98 logo sliding in with the left pane before the links in it are displayed. After that, the text on the right is displayed, and the application becomes interactive. When closing it, there will be an option to automatically start it on the next startup.
  • Internet Explorer and Outlook Express have been updated from versions 4.72.0103 to 4.72.0118. There are no major changes to either of them here.
  • This build introduces the setup parameters /ie for skipping the Emergency Boot Disk and /ih for skipping the registry consistence check. It also removes the note about the deprecated /n and /a parameters when starting setup with the /? argument.
  • This build introduces the final design of the IE 4.0 easter egg. It is stored in res://shdocvw.dll/wcee.htm.

Bugs and quirks[edit | edit source]

  • There have been differing opinions on whether this build is a Beta 2, Beta 2.1 or Beta 3 build, due to its unique branding, and the fact builds 1602 through 1624 use Beta 2.1 branding.
  • The Setup program throws up a lot of errors during system configuration, most of them being related to Internet Explorer's components. They have to be ignored to continue. Emulators like 86Box will run through the system configuration without any errors.
  • 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, 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. This is the last build to contain this bug.
  • Several items use wrong icons.
  • The default Active Desktop wallpaper remains broken if errors are encountered during system configuration.
  • If a new user is created in this build, the default login client will automatically switch to the "Microsoft Family Logon" client, even if the new user is the only one in the system. This was changed in later builds, where it needed to be installed manually and have two or more users in the system for it to work properly.
  • The volume control flyout is called "Master Out".
