Windows 1.0 had a hidden easter egg for almost 37 years

Almost 37 years after the official launch of Windows 1.0, Microsoft’s old operating system has given us a very pleasant surprise. is it a user revealed an easter egg that have remained hidden in software for decades. And although this is not something particularly new for the current times, where the Easter eggs are common in apps, games, series and movies, it was in the mid-1980s.

As Lucas Brooks posted on Twitter (via PCMag), the Easter egg in question consists of a list with the names of everyone who participated in the development of Windows 1.0. The really strange fact is that, among many others, appears Gabe Newell, who worked at Microsoft from 1983 to 1996, when he left the company to found Valve, the parent company of Steam.

Another striking aspect is how the Redmond company has managed to keep this Easter egg a secret for over three and a half decades. Brooks himself has indicated that he does not yet know how he is “naturally” activated, and that he managed to force it to appear after fixing some binaries. What is known is that the list was hidden in a bitmap image representing a smiley face.

And everything indicates that it was not the only Microsoft operating system to include a hidden credit list. Brooks explained that he spent several days reverse engineering other older versions of the software, such as Windows 2.0 and 3.0, with similar results. He even shared a file with the key combinations needed to make them visible; however, unforced access to Easter eggs Windows 1.0 is still a mystery.
