25 beautiful icon sets for Windows

I decided that I should showcase some of the most beautiful icons to go along with these themes. Choosing the icons turned out to be a lot harder than I had thought. There are so many beautiful sets and I know I'm not being fair by selecting only 25 of them. Those icons that didn't make it to this list, maybe some other time.
These icons can be applied using either IconTweaker or WinIcon, two of the best freeware icon changing application for Windows.
