Microsoft releases Windows 10 build 18358 to the Fast ring with more fixes

Windows 10 version 1903 is going to RTM pretty soon, and development of new features is pretty much done. As usual, Fast ring builds are rolling in more frequently than its usual once a week schedule. Microsoft released build 18358 to the Fast ring today, its second Fast ring build this week. The company has been sticking to a schedule of Tuesdays and Fridays.

Just as you'd expect, there are no new front-facing features in this build. However, there are a bunch of fixes, improvements, and known issues. Here's what got fixed and improved in Windows 10 Insider Preview build 18358:

  • FOR GAMERS: We have addressed an issue with Game Mode that may degrade game streaming and recording quality.

  • Here’s the latest on trying out our new Windows gaming technology:

    • Still haven’t had a chance to get the game State of Decay for free (for a limited time)? We’ve added even more slots! Whether you’ve tried it in earlier builds or haven’t had the chance yet, these instructions have everything you need.

    • Installed the Insider version of State of Decay already? We’ll be trying out another update later today. To get it, launch the Store app, click […] and then “Downloads and Updates”. Once installed, you shouldn’t see any difference in the game – it’s just a test update – but please let us know if anything doesn’t work!

  • We fixed an issue that could result in the thumbnails in Alt + Tab sometimes becoming offset.

  • We fixed an issue where certain upgrade paths could result in the contents of the Recycle Bin being left under Windows.old.

  • We fixed an issue resulting in upgrades failing at 18% or 25% and rolling back for some Insiders.

  • We fixed an issue resulting in some Insider experiencing green screens with error KERNEL_SECURITY_VIOLATION.

  • We fixed an issue resulting in some apps using the Windows Installer failing to install recently.

The interesting thing about the "new Windows gaming technology" is that Microsoft still hasn't said what it is. State of Decay isn't an Xbox Play Anywhere title, so it's either Win32 game support in the Store or bringing the Xbox One stack to Windows 10. Either way, we're really close to the Windows 10 version 1903 RTM, and it seems pretty late in the timeline to have unannounced features like that.

Here are the known issues:

  • Microsoft Store app updates do not automatically install on 18356+. As a workaround, you can manually check for, and install updates via the Microsoft Store app. Open Select “…” > “Downloads and updates” > “Get updates”.
  • Launching games that use anti-cheat software may trigger a bugcheck (GSOD).

  • Creative X-Fi sound cards are not functioning properly. We are partnering with Creative to resolve this issue.

  • We’re continuing to investigate feedback in the night light space.

  • Some Realtek SD card readers are not functioning properly. We are investigating the issue.

  • We’re investigating an issue preventing VMware from being able to install or update Windows Insider Preview builds. Hyper-V is a viable alternative if available to you.

  • If you install any of the recent builds from the Fast ring and switch to the Slow ring, optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.

Interestingly, the known issues list doesn't seem to be shrinking, something that should certainly happen before a public release. The RTM build should be available in the Fast ring before the end of the month, followed by a public release in April.
