Microsoft Rolls Out Windows 10 Redstone 4 Preview Build 17040


Microsoft on Thursday released Redstone 4 preview build 17040 to Insiders in the Fast Ring. This latest version adds a few new features, and unlike last week’s Build 17035, this one is available for PCs with AMD processors.

As Microsoft continues to move items from its classic control panel to the Settings app and one of the new improvements is the ability to adjust brightness for standard definition content color on a system in HDR mode. You will find the slider in Settings > System >Display.

There are also improvements to the touch keyboard including support for shape-writing for the wide full-screen keyboard. Before it was limited to just the one-handed keyboard.

Focusing on the touch capabilities in Windows 10, there are new improvements for the handwriting panel in this build as well. This includes new commit gesture and insertion gesture improvements.

Here is a list of the other improvements and fixes you can expect in this Redstone 4 preview build:

  • We’ve added settings that let you view and manage your activity history, which Cortana uses to let you pick up where you left off. Find these settings in Settings > Privacy > Activity history.
  • We fixed an issue where network profiles might change from Private to Public after upgrading to the previous build.
  • We fixed an issue resulting in checkboxes being missing from certain win32 apps.
  • We fixed a typo in the Windows Defender Security Center’s Controlled Folder Settings.
  • We fixed an issue resulting not being able to fully remove Windows.old in the last two flights.
  • We fixed an issue resulting in Narrator not saying anything when the candidate bar for hardware keyboard prediction opened. We also fixed an issue where Narrator wasn’t reading the word candidate when the focus moved into candidate bar.
  • We fixed an issue where the “Working on updates” screen was black with a small theme colored box instead of entirely theme colored.
  • We fixed an issue resulting in some Insiders experiencing a green screen on the previous flight with the error BAD_POOL_CALLER.
  • We fixed an issue resulting in UWP app sometimes leaving drop shadow leftovers after closing the window.
  • We fixed an issue where inactive window scrolling wouldn’t work if Excel 2016 was in focus.
  • We fixed an issue resulting in a noticeable flicker when using hotkeys or a precision touchpad to switch between virtual desktops.
  • We fixed an issue where the XAML Reveal light wouldn’t follow your mouse until the first mouse click – instead showing the entire element lit. This issue was visible in Settings and other XAML based UI in the last few builds.
  • We fixed an issue resulting in changes to Feedback Frequency in Feedback & Diagnostics Settings not persisting after leaving the page and returning.
  • We fixed an issue where Start wouldn’t open if you pressed the Windows key when the system menu from elevated Command Prompt or Task Manager window was open.
  • We fixed a rare issue where if you had certain streaming-capable apps on your PC before upgrading you might end up seeing a black screen with only a cursor for some time after logging in.
  • We fixed an issue from recent flights where the “Add” button in the PIN section of Sign-in Option Settings didn’t work for local accounts.
  • We’ve updated the icon for Collections in Cortana.
  • We’ve updated the touch keyboard so that the margin between each key is visual only. This change will be noticeable if you accidentally overshoot the key press by just a tiny bit – before it might seem as if key presses were being dropped in this scenario.
  • Based on your feedback, the feature to restore applications that have registered for application restart after you reboot or shutdown (through power options available on the Start Menu and various other locations) has been set to only occur for users that have enabled “Use my sign-in info to automatically finish setting my device after an update or restart” in the Privacy section under Sign-in Options Settings.

Insiders running the latest builds have access to early versions of Windows apps like Mail and Calendar, Photos, and Skype. Dona Sarkar notes that there’s a survey for insiders to complete to help the team improve the new apps. And, as is the case with all preview builds, there’s a list of known issues, too. You can view everything in Dona Sarkar’s blog post.

    This is excellent! So there is a “known” problem out in Windows 10 Creator’s Update (the one we have in the public release) with “We fixed an issue from recent flights where the “Add” button in the PIN section of Sign-in Option Settings didn’t work for local accounts.” Good to know they are aware and are doing something to correct this!

      It would be very helpful if you would report in ENGLISH. I don’t understand any of that gibberish you report in.
