As of 2024, finding a modern browser that supports Windows ME (Millennium Edition) can be quite challenging, as most contemporary browsers have dropped support for older operating systems. However, you might consider using older versions of browsers like Internet Explorer, Mozilla Firefox or Opera that were compatible with Windows ME. Specifically, Internet Explorer 5.5, Firefox 2.0 or earlier versions of Opera may still work, but keep in mind that these versions will not have the latest security features and may not render modern websites correctly. However, it is not impossible to browse the web on Windows ME (Millennium Edition) due to a really cool project called Browseservice which allows you to browse the modern web on old browsers such as Internet Explorer 5.5. You can learn about browseservice in this videoRegarding 8-bit games and programs, Windows ME is capable of running many 8-bit applications, especially those designed for DOS. However, compatibility can vary depending on the specific game or program. You may need to use DOSBox, a DOS emulator, to run some older DOS-based 8-bit games more effectively.
