Today Microsoft released Windows 10 Insider Preview Build 17093 for PC to insiders in the fast ring and to those who skip ahead. This was a big release with a lot of new features, changes, and bug fixes. Some of the new features that standout are a new button that will allow you to delete diagnostic data stored in Windows, new multi-gpu graphics settings, and WSL updates.

Delete Diagnostic Data

Recently Microsoft revealed that users will soon be able to see what diagnostic data is collected by Windows 10. In this build, Microsoft added a button that allows users to delete this data. This button is not currently working, but Microsoft has stated that it will be active before the release of Redstone 4.

New Application level settings for multi-GPU Systems

For those who have multiple GPUs in their computer, Windows will attempt to classify one of them as a "Power Savings" GPU and the other as the "High Performance" one. You can then configure applications to either be used in power saving or high performance mode, which would use the card that fits that category. 

Microsoft has stated that the motherboard embedded GPUs will typically be categorized as "Power Saving" and external devices, such as installed NVDIA and AMD cards, would be categorized as "High Performance". I am not sure how they plan on categorizing systems that have two external GPUs installed that are different brands such as a high end AMD and a high end NVIDIA card.

Windows Subsystem for Linux (WSL) improvements

This release brings some significant changes to WSL.  With this build, Windows applications and Linux applications can now communicate with each other over Unix sockets. This allows you to run an application in Windows that acts like a server, which can also be used by WSL applications.

Another interesting feature is the wsl.conf configuration file. This file allows you to configure various settings such as automounts, network configuration, and more that will be used every time you launch WSL. More info can be found here.

Known issues in Build 17093 

  • We have observed seeing longer-than-normal delays during install at the 88% mark. Some delays are as long as 90 minutes before moving forward. Please be patient as the install will complete successfully.
  • Some PCs will fail to resume from hibernate requiring a hard reboot to recover.
  • If you install a font product from the Microsoft Store, then later install a new build (feature update), the Store package will remain installed, but the fonts within the package are not installed. Until this is fixed, the temporary workaround is to uninstall the product from the Apps page in Settings, then re-acquire the product from the Store.
  • If an East Asian keyboard is the only input method on your system the touch keyboard will show an English layout with no IME on/off key. Until this is fixed, the workaround is to add a second keyboard language from the Region & Language Settings page, or to use the IME mode button in the taskbar.
  • We’re investigating an issue where the Japanese IME sometimes can’t turn on in UWP apps. If you encounter this issue switch to a Win32 application (e.g. Notepad), turn the IME on there, then switch back to the UWP app.
  • We’re investigating reports that 3 and 4 finger gestures on the touchpad have become unresponsive starting with the previous flight.
  • Windows Hello will fail to work on Surface Laptops with this build.
  • Plugging in an external optical drive (DVD) will cause an Explorer.exe crash.
  • Settings will crash if you open the Themes Settings page.
  • Buttons on Game bar are not centered correctly.
  • In some games—such as Destiny 2 and Fortnite—mouse and keyboard input will still go to the game while Game bar is open.
  • Selecting a notification after taking a screenshot or game clip opens the Xbox app’s home screen instead of opening the screenshot or game clip.
  • After Game bar closes, the mouse cursor resets to the position it was in when Game bar was opened.
  • Keyboard and mouse input may not work correctly in Game bar when playing a first person game (e.g. Minecraft). Alt+Tab out of and into the game should fix this.
  • In the text box for Mixer stream title, using non-character keys (e.g. Tab, Delete, Backspace, etc.) may cause the game to hang for a few seconds.
  • Bringing up Game bar using the Xbox button on an Xbox One controller doesn’t work in some games.
