Around the web we can find many minimalist versions of logos and packaging of well-known brands, and these examples are usually made by students or designers as personal work.
However in this case, Microsoft has developed a new logo, for its new operating system, Windows 8, based on the concepts of simplicity and clarity and using just a single blue colour. I think this is the most important point about the new logo. A representative explains:
It was important that the new logo carries our Metro principle of being “Authentically Digital”. By that, we mean it does not try to emulate faux-industrial design characteristics such as materiality (glass, wood, plastic, etc.). It has motion – aligning with the fast and fluid style you’ll find throughout Windows 8.
The new logo design has been made by Paula Scher at Pentagram and I really enjoyed it when seeing it for the first time.
