Setting your preference for apps that include accessibility in the Windows Store
Microsoft offer accessibility and language as preferences when choosing apps for Windows 8 and Windows RT
These instructions come from the Microsoft website
"You can set your preferences in the Windows Store so it's easier for you to find apps that use your preferred language or to find apps that are built with accessibility features. You can also choose whether you see app recommendations in the Picks for you list.
To set your preferences in the Store, follow these steps:
On the Start screen, tap or click Store to open the Windows Store.
Swipe in from the right edge of the screen, and then tap Settings.
(If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Settings.)
Tap or click Preferences.
Choose a preference to turn on or off:
Make it easier to find apps in my preferred languages — Shows only apps that support the preferred languages for your PC when you browse the Store. The supported languages for an app are listed in the Details section of an app's description page. You can change your preferred languages in the Region & language setting. For more info, see Add a language or keyboard.
Make it easier to find apps that include accessibility features — Shows only apps that meet accessibility requirements (determined by the publisher) when you search or browse the Store.
