Here's what's fixed and still broken in Windows 10 build 17017

Today, Microsoft released Windows 10 for PCs build 17017 to the Fast ring, offering a few new features that focus on Cortana and Settings.

This is a preview of the next feature update to Windows, codenamed Redstone 4, which should arrive sometime around next March. It's the first one to be released to all Fast ring users, rather than those that chose the Skip Ahead option.

As always, there are a bunch of fixes, improvements, and known issues to be aware of. Most importantly though, you should be aware of the fact that this is your last chance to switch off of the Insider Program before next year. After you install this build, the only way you can go back to the Fall Creators Update is a clean install of build 16299.

Here's what got changed, improved, or fixed:

We fixed an issue a small percent of Insiders were experiencing where uninstalled apps might unexpectedly reinstall after a reboot.

We fixed an issue where wallpaper changes might not roam to devices on the Windows 10 Creators Update with “Sync your settings” enabled.

We fixed an issue from the previous flight where Storage Settings would crash on launch.

We fixed an issue where changing time zones would result in the lock screen clock being incorrect until logging out and back in.

We fixed an issue where the Action Center wouldn’t scroll with touch if you started the scrolling motion on top of a notification.

If a notification doesn’t support being dismissed into the Action Center, the toast will now show an X instead of an arrow.

We fixed an issue where the touch keyboard might unexpectedly auto launch after a system restart on non-touch PCs if you’d used the touch keyboard prior to restarting.

We’ve updated the language settings icon in the input flyout to be consistent with that used in the touch keyboard.

We fixed an issue where the “2” character wasn’t rendering correctly in some apps when using the Courier New font.

We fixed an issue where duplicate icons might be displayed in the Volume Mixer when playing certain games or online videos.

We fixed an issue causing reduced performance in some DirectX 9 games running at high framerates. If you’re a fan of gaming, please take a moment to try playing your favorite games on this build and share feedback.

We fixed an issue where certain graphics drivers might result in night light displaying with unexpected colors when enabled in recent builds.

Going forward from this build, the settings to disable hibernate and Fast Startup will be preserved across upgrade.

We fixed an issue some Insiders were experiencing where after upgrading to recent flights their optical drive wouldn’t be listed under This PC.

We fixed an issue resulting in some Insiders seeing 0x80070005 when trying to upgrade to the last few flights.

We fixed an issue from recent flights where you might see code 0x80070002 when trying to update apps from the Store.

We fixed an issue where Hyper-V couldn’t create a VM on 3rd party network storage.

We fixed an issue where for the first few minutes after clean installing a non-English build many inbox app names might unexpectedly appear with English app names.

We fixed an issue where gaming apps using WebView with heavy use of HTML canvas might have unexpectedly had very low FPS in recent flights.

Here are the known issues:

Using a swipe gesture with touch to dismiss notifications from the Action Center is currently not working. We’re investigating – for now you’ll need to use the clear all button, or use mouse/keyboard.

If you RDP into a PC running this build with certain GPU configurations, when you go to sign in to the PC locally it will appear stuck at a black screen with only the cursor available. If you let it sit for a bit, the PC will eventually recover and you’ll be able to use it normally.

If you're on the Fast ring, you can get this build by heading over to Settings -> Update & security -> Windows Update -> Check for updates. If you're not, you can sign up by going to the Windows Insider Program tab and clicking 'Get started', since Redstone 4 previews are now open to everyone.
