Build 17025 includes revamped Ease of Access settings. Microsoft is grouping related settings together and improving the descriptions of the settings to make these accessibility features easier to discover, according to the blog post about today's build.
Microsoft also is updating the Advanced options under Settings so that Universal Windows Platform apps that are set to run at Startup will include a new option to see all available tasks specified by the app's developer, as well as their status.This test build also updates the Yahei font for Chinese (Simplified) to improve its legibility, symmetry and appearance, officials said.
Microsoft also mentions in today's blog post a few known issues (which is good, given the company stopped providing these known issues at the end of the Fall Creators Update testing process). Microsoft notes some may be having issues with some apps like Mail and Cortana, as well as missing some features like Windows Media Player. Some also may be encountering some Action Center issues around gestures and missing icons.
