How to identify the Windows in a CD without installing?

[johnye_pt]

I have some ISOs I'm renaming and storing, but I fail to see how to identify the Windows 9x/Me version of each ISO. With Windows XP we can look at the setupp.ini to identify OEM/Retail, does Windows 9x/Me have something similar? Most have OEMSETUP.EXE in the WIN9X folder, I'm guessing it means they're OEM. But what about the versions?

Also, all the ones I have are full install, but how to tell when they're upgrade?

EDIT: I could use this info, but installing all ISOs isn't as fun as it used to be

check ProductType in setuppp.inf in precopy*.cab to identify OEM/Retail/Upgrade.

For OS version, check user.exe in win*.cab.

check ProductType in setuppp.inf in precopy*.cab to identify OEM/Retail/Upgrade.

This. Here you have a list of known product types.

You could look at some of the files on the cdrom, such as the DOS files (command.com if it's there.)

The miniwin is only three versions, 95B and 98SE use 95 and 98 resp.

File dates are usually lined up with the version, eg 2222, 1111, 0950,

Thank you to all of you, specially to the msdn link I'll take a look at the ISOs this weekend and separate them accordingly.
