I was never a fan of Aero glass transparency as I prefer my operating system to use solid colors only and nothing else. I do however know a couple of Windows users who like the transparency effects of the operating system, and some were disappointed to find out that Microsoft removed the option to make windows transparent on Windows 8. It is not clear why Microsoft removed the options, but the most likely reason is that it shifted away from Aero in Windows 8 and that it may have felt that transparency did not fit with the overall look and feel of the operating system.
A method has been found recently to enable transparency in Windows 8 again and while it comes close to the Aero Glass Transparency feature of Windows 7, it falls a bit short as it won't enable blur or reflection effects. Other than that, it is a 1:1 copy of the Windows 7 transparency effects.
You need two programs to enable transparency on Windows 8 of which one needs to run in the background while the other is only used to prepare the system for it.
Guide to transparency
The first program that you need is Aero8Tuner, a free program that you can run right after you have downloaded it to your system.
- Make sure Enable Window Colorization is enabled.
- Set the Color Balance slider to the rightmost position.
- Check the Force High Contrast Mode option.
The second program that you need is Blend. This program needs to be run all the time for the transparency effects.
- Set the Global Blending slider to 254.
- Check the start at system booting option to run the program at every system start.
- Disable the system tray icon as it is not really needed.
I suppose users who desperately want to have transparency effects on Windows 8 won't mind that Blend needs to be run at startup to achieve that effect. You can undo the changes easily by removing the start at system booting option in the Blend preference and disabling the force high contrast mode option in Aero8Tuner. (via)
