We’re only two days into the week, but there’s already some big Windows Insider action to go around for the next few days. Indeed, Microsoft just pushed out Windows 10 Insider Preview Build 17728, and this time Microsoft is teasing that a working version of its much-anticipated Your Phone app is coming soon. As usual, though, there are a few known issues and fixes which you need to take note of. Please find these below.

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 resulting minimized apps having squished thumbnails in Task View.
  • We fixed an issue where when open Task View would crash if you pressed Alt+F4 and Timeline was enabled.
  • We fixed an issue where Timeline’s scrollbar didn’t work with touch.
  • We fixed an issue where the top border of UWP apps would still be accent colored even if having an accent colored border was disabled in Settings.
  • We fixed an issue resulting in the tops of apps in tablet mode being clipped (i.e. missing pixels).
  • We fixed an issue where the taskbar would stay on top of full-screened apps if you had previously hovered over any grouped taskbar icon to bring up the extended list of previews, but then clicked elsewhere to dismiss it.
  • 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 Find on Page in Microsoft Edge would stop working for open PDFs once the PDF had been refreshed.
  • We fixed an issue where Ctrl-based keyboard shortcuts (like Ctrl+C, Ctrl+A) didn’t work in editable fields for PDFs opened in Microsoft Edge.
  • We fixed an issue where the icons in the Microsoft Edge extension pane were drawing unexpectedly close to the toggles.
  • 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 notification area (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 fixed the issue where if the Narrator key is set to just Insert, sending a Narrator command from a braille display should now function as designed regardless if the Caps Lock key is a part of the Narrator key mapping.
  • We fixed the issue in Narrator’s automatic dialog reading where the title of the dialog is being spoken more than once.
  • We fixed the issue where Narrator won’t read combo boxes until Alt + down arrow is pressed.

Known Issues:

  • We’re progressing in our work on adding dark theme in File Explorer and the Common File Dialog – you’ll notice improvements in this build, although we still have a few things left to do. You may see some unexpectedly light colors in these surfaces when in dark mode and/or dark on dark text.
  • There is an issue impacting WDAG, Remote Desktop and Hyper-V. Remote Desktop Client (mstsc.exe) users will see a misleading error dialog complaining about low virtual memory when a connection is being established. As a workaround, they can ignore that error dialog by just leaving it there. If they dismiss the error dialog, the connection will be severed. And users won’t be able to use enhanced session in Virtual Machine Connection (vmconnect.exe). As a workaround, they can stick with the non-enhanced session.
  • When you upgrade to this build you’ll find that the taskbar flyouts (network, volume, etc) no longer have an acrylic background.
  • 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.
  • When you set up Microsoft Edge as your kiosk app and configure the start/new tab page URL from assigned access Settings, Microsoft Edge may not get launched with the configured URL. The fix for this issue should be included in the next flight.
  • On Build 17723 (but not Build 18204), you may see the notification count icon overlapping with the extension icon in the Microsoft Edge toolbar when an extension has unread notifications.
  • On Windows 10 in S Mode, launching Office in the Store may fail to launch with an error about a .dll not being designed to run on Windows. The error message is that a .dll “is either not designed to run on Windows or it contains an error. Try installing the program again…” Some people have been able to work around this by uninstalling and reinstalling Office from the Store. If that doesn’t work, you can try to install a version of Office not from the Store.
  • When using Narrator Scan mode you may experience multiple stops for a single control. An example of this is if you have an image that is also a link. This is something we are actively working on.
  • When using Narrator Scan mode Shift + Selection commands in Edge, the text does not get selected properly.
  • We’re investigating a potential increase in Start reliability and performance issues in this build.
  • After setting up a Windows Mixed Reality headset for the first time on this build with motion controllers, the controllers may need to be re-paired a second time before appearing in the headset.
  • When using a Windows Mixed Reality immersive app, saying “Flashlight on,” may fail to activate the flashlight feature even though the status appears as active on the Start menu.

In addition to the above, developers should take note of a known issue where enabling developer mode will fail if switching from Fast ring to Slow ring. You’ll have to remain in the Fast Ring to add/install/enable optional content.
