Another programmer named Bruce Jensen published a similar utility called "Revenge of Mozilla", which was freeware and removed many other Windows 98 components identified as "bloatware" or as being of questionable value. Although Revenge of Mozilla asked the user to supply some files from the Windows 95 OEM Service Release 2 version of the Windows Explorer shell (necessary for compatibility with the FAT32 file system) that did not have the "Windows Desktop Update" that came with Internet Explorer 4/Windows 98. As a result of the shell replacement, Windows used significantly fewer resources than normal, the shell didn't leak resources like Windows 98's version did, and Windows crashed less. In 98Lite, using Explorer from Windows 95 OSR 2 was optional.
