Microsoft is hoping to reinvent the desktop experience with Windows 8 and its Modern UI. The OS represents a massive change in the traditional desktop user interface, and it looks like Redmond is looking to give itself a little makeover, too. Microsoft today unveiled a brand new corporate logo. This is the first major Microsoft logo change in the company's history. It's been 25 years since we've updated the Microsoft logo and now is the perfect time for a change.
This is an incredibly exciting year for Microsoft as we prepare to release new versions of nearly all of our products," he wrote, later adding, "This wave of new releases is not only a reimagining of our most popular products, but also represents a new era for Microsoft, so our logo should evolve to visually accentuate this new beginning.
