If you're using Windows 98 and don't want to upgrade to Windows 98 SE but do want the bug fixes that are included in the newer release, your salvation has arrived: Microsoft has posted the components of Service Pack 1 (SP1) for Windows 98 to its Web site, set of separate downloads that include three Year 2000 fixes, Internet Explorer 4.01 SP2, an updated Java virtual machine and an important 1 MB "System Update" that includes numerous networking, security, and accessibility fixes.
Ostensibly, these fixes are available now from the Windows Update Web site. However, since I have no way to verify this, I do know that they are also available from the "Download Windows Updates" page on the Microsoft Web site.
If you'd rather receive the SP1 fixes on CD, you can order a $5.00 SP1 CDROM from Microsoft or get the fixes as part of the $20 SE Updates CDROM, which updates your Windows 98 system to Windows 98 S
