General changes, improvements, and fixes for PC
The build watermark at the lower right-hand corner of the desktop is no longer present in this build. This does not mean this is the final build as we are not done yet. We’re just now beginning the phase of checking in final code to prepare for the final release.
We fixed an issue resulting in the back button in Settings and other apps becoming white text on a white background if you hovered over it.
We fixed an issue resulting in Narrator not reading selected word choices when typing using an IME (for example, in Japanese).
We fixed an issue resulting in certain apps crashing when you tried to save a file from the app.
We fixed an issue resulting in explorer.exe crashing recently when clicking on the “Import photos and videos” option from an autoplay notification.
We fixed an issue resulting in nearby sharing not working for local accounts where the account name contained certain Chinese, Japanese, or Korean characters.
We fixed several bugs causing text clipping issues when you use “Make text bigger” setting in Ease of Access.
