Since I having eye disabilities I use the enabled black based High-Contrast-Mode (high-contrast-#1 theme/design) on Windows 7 and Windows 10.
Since the installer and the updater are strictly "branded" with white background images, there is already a problem, since white as background is not that "mandatory" (MSDN rules) high-contrast support.
On Windows 7 the text in the installer or at the last updater screen is yellow and so yellow on white background image.
On Windows 10 it is white texto n white background image.
To test it on your self:
- use LeftShift+LeftAlt+PrintScr to enable or diable the high-contrast-mode
- switch through the high-contrast designs to test the visual results.
I really would appreciate, if some changes will take place to support accessibility helpers (MSDN: mandatory accessibility support).
P.S.: Desktop Zoom is mostly ignored, too on my Windows 7 office desktop.
