If you’re one of the many users who rushed to download and install the leaked Windows 10 build 9901, you most likely noticed the subtle visual tweaks that the company introduced here and there in order to make its new operating system more visually appealing.

This process actually started when the first Technical Preview build got out, coming with a number of UI enhancements suggesting that Redmond was at least pondering a revamp of the traditional Windows desktop.

In build 9901, Microsoft has implemented not only smaller icons for the taskbar and new Metro app control buttons, but also a bunch of new icons which can be easily spotted in File Explorer when browsing locally stored files.
