Windows 10 Build 9650 «FHD 2026»

You won't find Windows 10 build 9650 on any official Microsoft download page. It was never intended for the public. However, it remains a topic of interest for a few reasons:

The single most important change in build 9650 is hidden in plain sight: you can now resize Modern (Metro) apps like desktop windows. In Windows 8.1, Store apps ran full-screen only (or snapped to the side). In 9650, you can drag a corner of the Mail app to resize it arbitrarily. The title bar still uses the massive 8.1-style font, but there is a new close button (the traditional X) in the top-right corner. This was radical. This was the precursor to the Universal Windows Platform (UWP). windows 10 build 9650
