Two different Windows 98 FE OEM CDs

I've been creating ISOs of my old Windows CDs recently and noticed that I have two different Windows 98 OEM CDs in my collection.

The first one is the same as the OEM Full ISO on this website:
0398 X03-36182
SHA1: c95fe41b1bc7c83e16bdd9ec8cbd97866552a06b
Timestamp: May 11th, 1998 at 20:01

But the other one is a slightly newer one:
1298 X04-04214
SHA1: 52ec5d1376036bf3f0edfb1ce7647c3bb04dc696
Timestamp: November 24th, 1998 at 08:02

Does anyone know the difference between these? I found a forum post on MSFN which claimed that the newer version is missing the MS Java VM but I installed it in VMware Workstation as a test and can confirm that the JVM is present and working. The timestamps of the installed files are May 11th, 1998 at 19:01 (so an hour out compared to the original Windows 98 CD).

  • The only good way to determine diffs is to unpack each iso to a directory on your local drive, then use a binary compare tool. I have found several SE and Office 2K iso differences in just this same way.

    I decided to extract every CAB file in the win98 folder to see what I could find based on the timestamps. Easy to do with:

    extract /a base4.cab /e /l c:\win98

    Almost every file has the May 11th, 1998, 19:01 timestamp. The exceptions are as follows. Most of these are Java-related so maybe they released a new version of the JVM on the disc?
