Last Tuesday Microsoft released Windows 10 Insider Preview Build 15046 for PC to Windows Insiders in the Fast ring. This Build seems a lot more stable than the previous one… Enjoy upgrading!

As you can see, we have done quite a few experiments in the Creator’s Update so far to try out different colors and icons and we have loved co-creating the results you see today with you.

What’s new in Build 15046

Color of Cortana’s home on the taskbar: You had a LOT of opinions on this topic and we have been loving the enthusiastic feedback coming in! We finished our experiment with the color of Cortana’s home on the taskbar and for now, it’s back to the color it was before. Thanks for your feedback on this change.

Windows Defender Improvements: Windows Defender Security Center has added a notification icon to the notification area so you can see your protection status at a glance. You can also easily launch the app from the notification icon. Windows Defender Antivirus notifications also now lead to Windows Defender Security Center when clicked. Also: Windows Defender Security Center can now be launched directly from the Settings app and the “App and Browser” page is now functional.

Pick up where you left off in Cortana: We are experimenting with how we display what you can pick up where you left off across your devices in Cortana. Cortana now proactively shows you apps, files and websites from Microsoft Edge. Previously, this feature only displayed websites from Microsoft Edge in Action Center. Let us know what you think! (Available EN-US only.)

Improved translations: For Insiders who speak non-English languages, we wanted to let you know that we have heard your feedback on our translations and have been actively making improvements. With this build you should see improvements – particularly in OOBE and for some of our newer settings, but across the system as well. We encourage you to take a look around the system, and if you spot anything translation that doesn’t quite seem on point, please log feedback using the steps here.

Updated Gaming Settings icon: A lot of you sent in feedback on this. We listened and adjusted the Gaming icon in Settings to feel more inline with the other icons on the Settings home page.

Application Installation Control: You now have the option to control what type of apps are allowed to install on your PC. This setting is available by going to Settings > Apps > Apps & features. You can choose to only allow installation of Store apps, choose to be warned when installing a non-Store app but allow their installation, or choose to allow installation of apps from anywhere.

When you choose either of the Store options, you’ll see a warning when attempting to install a non-Store app. The warning will direct you to the Store where you can download an alternate app if available. In some cases, when there’s already an equivalent app in the Store, the warning will provide link to that app. This is an opt-in feature, and the default setting is to allow installation of apps from anywhere. (Note: This went live with last week’s build.)

  After updating to a new build, we’ve updated the text on the welcome screen to say “Might take several minutes” instead of “Might take several minutes or so”. Thanks to everyone who sent feedback on how the original phrasing was overly casual.

Known issues for PC

• Some PCs will fail to update to this build at 71% and roll-back to the previous build. See this forum post for details.
• [GAMING] Some popular games might minimize to the taskbar when launched. You can click on the game on the taskbar to get the game back.
• [GAMING] Certain hardware configurations may cause the broadcast live review window in the Game bar to flash Green while you are Broadcasting. This does not affect the quality of your broadcast and is only visible to the Broadcaster.
• Some UWP apps may unexpectedly appear with their app package in the title bar as opposed to the app name.
• Pressing F12 to open the Developer Tools in Microsoft Edge while F12 is open and focused may not return focus to the tab F12 is opened against, and vice-versa.
• Sometimes launching F12 will launch the F12 window behind the active Microsoft Edge window.
• ADDED: Insiders with multiple monitors may encounter an issue where one of the monitors stops rendering (with the exception of the mouse). While rebooting will fix it, you can also resolve the issue via Settings > System > Display under the Multiple displays section, set it to only use the monitor that’s functional, then set it back to “Extend these displays” and the issue should be resolved.
• ADDED: Some Insiders are reporting getting an 0x80070228 error when attempting to download this build. See this forum post for details.
