Let’s rewind the clock to 2009. Windows 7 has just launched, and the world is exhaling a collective sigh of relief. After the divisive experiment that was Windows Vista, Microsoft needed a palate cleanser —a stable, fast, and user-friendly OS. But hardware alone doesn’t make an operating system legendary.

One app would overwrite a shared system file, and suddenly your printer would start playing “Flight of the Bumblebee” while Photoshop crashed. .NET introduced a managed runtime —a protective bubble where code ran safely, versioned cleanly, and didn’t interfere with other programs.
