A source for some legacy Windows files and applications that are sometimes helpful.
If you need to download these from an actual vintage browser, go to old.ibmfiles.com which has HTTP support. Yeah, I get mad too when I just need to download one of these from a vintage browser and everything is locked to HTTPS.
General
Windows 98
Windows 98 / 98SE is still commonly used by enthusiasts who need it for the DOS support, or raw 9x support-- generally for games. Here is a collection of applications and updates used in conjunction with Windows 98.
*If you need to configure AUTOEXEC.BAT for your SB16 for a non-plug and play, which is highly recommended, then it would go something like this (also remember to place this driver in C:\SB16 or modify the below fields referencing to wherever you put it):
SET SOUND=C:\SB16
SET BLASTER=A220 I5 D1 H6 P330 T6
C:\SB16\DIAGNOSE.EXE /s
LH C:\DRIVERS\MOUSE\CTMOUSE.EXE
LH C:\WINDOWS\COMMAND\MSCDEX.EXE /D:CDROM001 /L:D /M:15
Note: ensure you update the correct IRQ and DMA that yours is jumpered to, above it's IRQ 5 and DMA 1.
Windows Vista
Both 32-bit and 64-bit binaries are included in each zip file, unless there's only one 32-bit release which is the case for some of the applications. Some of these also work on XP and Windows 7.
