Microsoft has never released a service pack for Windows98 SE, but I made a Service Pack for Windows98 SE users.
It contains all Windows98 SE updates from Windows Update site and more.
It is a self-extracting and self-installing pack like Microsoft's update files. Thus, you cannot choice files individually. However, the pack installs only required fixes for your system.
Uninstallation is possible from Add-Remove Programs.
This is only for WINDOWS 98 SECOND EDITION ENGLISH. I highly recommend that you should backup your system before installing the pack.
It contains only operating system updates. It does NOT contain Internet Explorer 6, DirectX 9, Media Player 9 and their updates.
Note: All old version users should install this version without uninstalling old version
What's New in This Release:
? ADDED: 2 new hot-fixes (192425, 246817).
? ADDED: All cosmetic enhancements of SP 1.6 such as Windows 2000 Desktop Icons. (Sorry, but they are not optional).
? FIXED: Lots of bugs are fixed. (MaxCachedIcons typo bug, %DosNameHere" bug, Verinst.exe uninstallation bug, 256-color tray icons bug, Notepad patching on Sleek bug, Executing SP from different drive bug.)
? REMOVED: General USB Mass Storage Device Drivers. (I recommend a much better generic drivers: http://rapidshare.de/files-en/516500/nusb20e.exe.html. My drivers doesn't support some devices and it has some bugs, we have a good alternative, so I removed it.)
