Windows 10: The installation interface has been updated
Microsoft has been slowly updating nearly every aspect of Windows 10
but one area that remained unchanged, for many years, is the UI used during installation. In newer builds of Windows 10, the UI has finally updated and while I do not have an actual picture to show you, since the layout is quite basic, we have mocked up, identically, what current versions look like. To be clear, I have seen this UI and it looks like what you see below.
The new interface focuses around a center ring that acts as a progress bar and along the bottom of the UI are the various steps of the installation process. The top of the screen says "Installing Windows 10 Technical Preview" and below that "Your PC will restart several times. Sit back and relax".
