Usually I always post my tricky little discoveries right away – not least to be able to look them up here again at any time, in case I forget them. But as for this subject, I thought some time ago that I could remember it anyway and that nobody else would be interested in it either. Think again! Today I needed it again and couldn’t remember. ;)
What I’m talking about? In the Aero designs of Windows 7, you can adjust just about everything – window colors, window transparencies and all that stuff. What you can not adjust, however, are those rotten glass reflections that are visible as diagonal lines on all window borders.
I think many people don’t even notice the reflections. Back then, I had asked several people if they knew how to disable this effect. But they claimed they didn’t have any glass effects. However, when I demanded proof screenshots, it turned out that they had these lines on the windows, too! :D
I guess many people won’t understand how anybody could be bothered about something so unimportant. But at least I’m not the only one! In a Windows 7 forum someone else was upset about it, too, and I also found the solution there.
In short: Open the Registry Editor (Start Menu → type
regedit.exe → Enter), press Ctrl+F and search for the key
ColorizationGlassReflectionIntensity. After you’ve found the entry, double-click it, enter a 0 (zero) as value and confirm with “OK”. The change will take effect at the next logon.
Note: As soon as you make any changes to the “Window Color” on the control panel page “Personalization” (see picture), the stupid effect will automatically be enabled again, and you must once again set the value in the registry to 0. So you should first perfect your design and then remove the glass effect.
