Microsoft has released its new logo.
It's the first serious change to the four-colored window theme logo in 25 years.
A company blog notes:
The Microsoft brand is about much more than logos or product names. We are lucky to play a role in the lives of more than a billion people every day.
The ways people experience our products are our most important “brand impressions”. That’s why the new Microsoft logo takes its inspiration from our product design principles while drawing upon the heritage of our brand values, fonts and colors.
