Today, Microsoft is rolling out a new preview build for the Windows Insiders in the Fast Ring. Windows 10 Build 17746 comes with a bunch of improvements, fixes, and as well known issues. You can check out all the details below.
In the same
blog post, Microsoft's Dona Sarkar and Brandon LeBlanc also announced that the Your Phone app is now available for the Release Preview Ring Insiders with PCs running Windows 10 April 2018 Update. If you're a Skip Ahead Ring Insider,
you'll receive a new version of Screen Sketch app (now known as Snip and Sketch) with a new delay snip feature.

This build has fixed an issue with Narrator where the app would incorrectly report some standard combo boxes as “editable combo box” instead of “combo box”. Microsoft has also addressed an issue with Windows Mixed Reality where the motion controllers need to be repaired after initial setup before appearing in the headset. You can find the full changelog below:
General changes, improvements, and fixes for PC♦ We fixed an issue where Narrator would incorrectly report some standard combo boxes as “editable combo box” instead of “combo box”.
♦ We fixed an issue in Windows Mixed Reality causing motion controllers to need to be repaired after initial setup before appearing in the headset. If you still experience this, please file feedback in Feedback Hub.
♦ We fixed an issue for Japanese and German where when you reset your PC (from
Settings >
Update & Security >
Recovery) the progress percent would be written in the middle of the string rather than at the end.
♦ We fixed an issue when using Italian as your display language where the Yes button to confirm file deletion would sometimes disappear when trying to delete a OneDrive file via File Explorer.
♦ Thanks to everyone that’s shared feedback about naming the tabs you’ve set aside in Microsoft Edge. We’re evaluating the right approach for this feature and in the meantime, it has been removed from RS5 builds.
Known issues♦ You may experience a bugcheck (GSOD) when logging out of your user profile or shutting down your PC.
♦ When you use the Ease of Access Make Text bigger setting, you might see text clipping issues, or find that text is not increasing in size everywhere.
♦ Narrator sometimes does not read in the Settings app when you navigate using Tab and arrow keys. Try switching to Narrator Scan mode temporarily. And when you turn Scan mode off again, Narrator will now read when you navigate using Tab and arrows key. Alternatively, you can restart Narrator to work around this issue.
The bug fixes are indeed important because the release of Windows 10 version 1809 (Redstone 5) is just around the corner. According to Microsoft's typical schedule, Windows 10 Redstone 5 RTM Build will be compiled and shipped to the Insiders next month. In October, Microsoft will release Windows 10 Redstone 5 gradually to the general public across the world.
