The logo honestly looks like something that was created with MS Paint.
I think the (now) old logo was more of a logo and could have been represented in any colour. It was also a sign of trust that (at least my generation) grew up with. The new one just isn't attractive, nor does it really look like a logo.
I expect Microsoft to change their logo again within the next 5-7 years.
