Over the years, Microsoft has embedded secret easter eggs into their operating systems. Some have surfaced over time, but a brand new one has just been found after being hidden for over 25 years. Even the original software developers only vaguely remember creating it.
Back in the days of early Windows operating systems, there were a number of hidden easter eggs purposefully embedded into the software. Over time, the public would find them and it would make the news. Easter eggs, such as basic hidden games, pictures of the development teams, music and a few more have all been widely popularised. But, in March 2021, a new easter egg was found in the Windows 95 operating system, and it has been confirmed by the original developers of Microsoft Windows 95.
If you wanted to have a look at this easter egg, you'd go to Start > Internet Mail > Help > About Microsoft Internet Mail and News. Then, select one of the file names and just simply type "Mortimer". What happens next is that you'll be presented with a scrolling list of all the developer's names who worked in the Microsoft Athena development team.
