Microsoft Windows

Windows XP (2001–2014)
In 2001, Microsoft overhauled the Windows logo again giving it much more of a clean feel. The Windows logo was simplified, removing the black borders and squares flowing behind it. The logo was also given a 'plastic' feel to it. It was created to match Windows XP which had a very clean feel. It used the Franklin Gothic Medium font for the text.

Windows Vista (2007–present)
Microsoft modified their 2001 logo, getting rid of the plastic feel and changing the font to Segoe.

Windows 8 (2012–2016)
Microsoft overhauled their logo again to fit in with the new Metro design language on Windows 8, which uses one-color designs and a slightly modified Segoe font. This logo was unveiled on Windows 8 Consumer Preview released February 2012. Instead of using the waved windows design, it uses the real window design, with perspective.

Windows 8.1 (2013–present)


After a year, Microsoft released Windows 8.1 in 2013. This logo has an additional ".1" at the end. This logo is also slightly less bold, giving a smoother feel.

Windows 10 (2015–present)


Microsoft officially unveiled the first beta version of Windows 10 on September 30, 2014. The text on the wordmark of the logo was unbolded and the logo itself was made a darker shade of blue. The final version of the operating system was released worldwide on July 29, 2015.

Windows XP - 7 (2001-present)


This is a flat version, with the white version used for Vista beta "Longhorn" in milestone 9 or 10, before the final beta.
