I just moved my SW's to a new laptop with windows 10. Prior it was fine, now it's way to small to read. Was supported by windows 7.
Solidworks 2014 isn't compatible with Windows10
I've never seen Windows 10, but SolidWorks 2014 should have the options shown below to adjust the size of the icons.
Just wait until you upgrade to SolidWorks 2016 / 2017 and get to experience the joy of the new blue/grey icons (hint: they suck).
