The Windows DVD installer has looked almost exactly the same since 2013, even with the same color schemes for Client and Server. It still resembles Aero and has a lot of skeuomorphism, which makes it inconsistent with the rest of Windows 10's UI. I think it could be updated with the following changes: 1. Background should be Light Blue (as this is the default color used by Windows 10); 2. The main install window border should lose its rounded corners and be colored white or a lighter gray, to resemble paper. 3. All buttons as well as the partition selection effect should lose all the skeuomorphism, becoming flat and rectangular; 4. The install icon on the upper left corner of the install window should be just a small light-blue arrow pointing down. 5. Finally, the progress bar on the bottom of the screen should be changed from green to a dark blue. This is just my humble opinion, what do you think? I also submitted this on the feedback hub, although I doubt Windows' devs will ever consider it.
