Were there any other editions of Windows 98 or 98SE released? By other editions I mean other than upgrade/retail/oem? I know back many years ago I had a version of Windows 98SE that in MSINFO said "Clean install using Select CD". I don't have the original CD of this now. It still required a product key but they were different from retail or OEM keys (would not accept them) h t t p: / / w w w . msfn.org/board/topic/86212-product-type-of-windows-959898seme/ Also this entry 100 - Clean install using Microsoft Internal - This was a build that was used internally by Microsoft employees. I know lots of people changed the settings in an INI file to fake this build as it did not ask for a product key. I had (infact still have!) the genuine Microsoft build of Windows 98 (First Edition) on a Microsoft branded Windows CD-R. I was at Uni back in those days and a mate of mine worked for Microsoft sent it less than a week after the files were built - and long before any "warez" type release appeared. So was wondering if any of those builds ever leaked out?
