We fixed an issue where Ctrl + 0 to reset the zoom level in Notepad wouldn’t work if the 0 was typed from a keypad.
We fixed an issue where nearby sharing would become blocked on the sender device after canceling share to three different devices.

We fixed the issue where Narrator said “Not a Narrator command” when navigating Win32 menu bar items.
We removed the Windows alert sound when performing the Narrator Find command.

Windows 10 Insider Preview Build 18214

Today, we are releasing Windows 10 Insider Preview Build 18214 (19H1) to Windows Insiders who have opted in to Skip Ahead.

General changes, improvements, and fixes for PC
We fixed the issue resulting in the Clock & Calendar flyout sometimes not appearing until you clicked Start or the Action Center. This same issue impacted both notifications and the taskbar jump lists appearing. Thank you to all the Windows Insiders who gave feedback on this issue.
We fixed an issue that could result in an unexpected sihost.exe error when entering Safe Mode.
We fixed an issue where Timeline’s scrollbar didn’t work with touch.
We fixed an issue where when naming a tile folder in Start it would commit as soon as you pressed space.
As some keen eye’d Insiders noticed, we’ve been working on our scaling logic and you should find apps resize better now after monitor DPI changes. As always, we appreciate feedback in this space, so let us know if you have any issues.
We fixed an issue where the enabled/disabled state of Fast Startup would be reset to default after upgrading. After upgrading off of this build your preferred state will persist.
We fixed an issue where the Windows Security icon in the taskbar systray would become a little bit blurrier every time there was a resolution change.
We fixed an issue where the USERNAME environment variable was returning SYSTEM when queried from an un-elevated Command Prompt in recent builds.
We’ve updated the messaging in Snipping Tool to more closely align with the commitment we made here. You’ll also notice in the message that we’re exploring renaming our updated snipping experience – bringing together the old and new. The app update with this change hasn’t flighted yet, but if you have any feedback on the subject we’re open to hearing it.
