I'm going to post some feedback. If you don't like it, too bad, because I'll do my best to stay sweet and polite. 1. Not as blingy as Win7's aero, but I won't nitpick; for Aero on Win8, this is neat. 2. I thought Aero was all about transparency? Then why, after changing the desktop wallpaper, am I still stuck on that bright orange window colour?
This is a common misconception. Aero is the new compositor introduced in Vista. It's GPU-accelerated desktop graphics. Aero Glass is a particular faux-glass transparent theme that uses Aero. Aero is a technology. Aero Glass is an appearance. Two very different things. When people talking about Windows 8 "removing Aero", they mean "Aero Glass". In fact, you can no longer disable Aero in Windows 8 (you could disable Aero in Vista and 7).
"Created by"? Pfft. Don't give the guy too much credit. The aerolite.msstyles file comes installed with Windows (poke around C:\Windows\Resources\Themes and you'll see it). It's just that none of the default themes use it. All he did was edit the default aero.theme file (it's just a standard Windows INI file) and change the style file to point to aerolite.msstyles instead of the default aero.msstyles. Oh, and he also changed the "Copyright © Microsoft Corp." to "Created by Sergey Tkachenko" because, hey, why not claim credit for a 4-byte change?
BTW, in case anyone is wondering, "Why did Microsoft include a theme that it doesn't use?", it's because this is the default style for the Server editions of Windows. So it might be better to just call it "Server style" instead of "Aero Lite style".
Google search for screenshots of Server 2012 R2. No, it's finished. Have you ever used Windows Server before? Prior to Server 2012, Server had the Classic (i.e., Windows 2000) appearance. It is supposed to be spartan and bare-bones. Now that you can't turn Aero off, this "lite" theme is the closest analogue to running on the classic theme. This is not supposed to look like a pretty end-user consumer theme.
