What’s New In Windows 10 Insider Preview Build 18290

Microsoft has released Windows 10 Insider Preview Build 18290 (19H1) to Windows Insiders in the Fast ring on Nov 28, 2018. Please note that these builds are in early development state and may contain bugs which may cause loss of data to some users in worst cases. In case you don’t wish to receive these builds, you can opt out of Windows Insider program or switch to Slow ring. Builds in the Slow ring are of better quality and have more stability as compared to Fast ring.

Expiry Date for Insider Builds

Windows 10 Insider Preview builds have a built-in expiration date which Microsoft refers as a “timebomb”. This is no new practice, it has been there since the first Windows 10 Insider Preview build. This timebomb makes sure that Insiders are up to date with the latest features and quality updates. After the expiry date of Build, Insiders will receive a warning that the build has expired and will get that warning once a day. Build Expiry notification is applied to Insiders in both the Fast and Slow rings to make sure they are running the latest builds available to those rings.

Insiders in the Fast ring need to update to 19H1 Build 18290 to avoid hitting the timebomb set to Dec. 14th. Additionally, Insiders in the Slow ring running older builds need to update to Build 17763 (the final build for the October 2018 Update). If you are an Insiders, you can check your flight settings and verify if you have latest builds by going to Settings > Update & Security > Windows Insider Program. You can check the build expiry date of your Insider Preview build by typing WINVER in search on the taskbar or Start.

Here is the compiled list of new features, improvements and changes available in Windows 10 Insider preview build 18290.

Following up on jump list improvements in Build 18282, Microsoft has polished up the power and user menus in Start as well. Also added icons in menus for easier identification. you can have a look at the below screenshot:

This will also be visible in the power menu on the sign in screen.

2. Manually Sync your clock

In response to Insiders’ feedback, Microsoft has added an option in Date & Time Settings which allows users to manually synchronize your clock with the time server. Using this feature you can synchronize your clock when you think the clock might be out of sync, or if the time service has been disabled. It will also show the last time when the clock was successfully synced, and the address of time server currently in use.

Note: This feature is currently only supported for non-domain joined PCs, although in build 18290 it will be visible on all devices.

3. See which app is using your microphone

In Build 18252 Microsoft introduced a new mic icon that would appear in the notification area allowing you to know if an app was accessing your microphone. After installing Build 18290 build, if you hover over the mic icon, it will show you the name of app which is using your microphone currently. Double clicking the icon will open Microphone Privacy Settings.

Showing hovering over the microphone button, with a tooltip that says “Windows Voice Recorder is using your microphone.

If multiple apps are using your microphone, then it will just list how many are actively using your microphone.

General changes, improvements, and fixes in Build 18290

  • Fixed an issue resulting in PDFs opened in Microsoft Edge not displaying correctly (small, instead of using the entire space).
  • Fixed an issue resulting in mouse wheel scrolling in many UWP apps and XAML surfaces being unexpectedly fast in recent builds.
  • Made some updates to the taskbar to reduce the number of times you may see the icons redraw. Most noticeably when interacting with the recycle bin, although in other scenarios as well.
  • Antivirus apps must run as a protected process to register with Windows and appear in the Windows Security app. If an AV app does not register, Windows Defender Antivirus will remain enabled.
  • Fixed an issue resulting in the System unexpectedly consuming a high amount of CPU for prolonged periods of time when enumerating Bluetooth devices.
  • Fixed an issue resulting in Cortana.Signals.dll crashing in the background.
  • Fixed an issue that caused Remote Desktop to show a black screen for some users. This same issue could also cause freezes over Remote Desktop when using VPN.
  • Fixed an issue resulting in mapped network drivers potentially displayed as Unavailable when using the net use command, and displaying a red X in File Explorer.
  • Improved compatibility of Narrator with Chrome.
  • Improved performance of Magnifier centered mouse mode.
  • Fixed an issue where the Pinyin IME would always show English mode in the taskbar, even when typing in Chinese in the previous flight.
  • Fixed an issue resulting in languages showing an unexpected “Unavailable input method” in their list of keyboards in Settings if you added the language via Language Settings in recent flights.
  • Added support for LEDBAT in uploads to Delivery Optimization peers on the same LAN (behind the same NAT). Currently LEDBAT is only used by Delivery Optimization in uploads to Group or Internet peers. This feature should prevent congestion on the local network and allow peer-to-peer upload traffic to back off instantly when the network is utilized for higher priority traffic.
