Please note that preview builds are not final versions of Windows 10 and may contain bugs or issues that could affect your PC's performance or data. Before installing any preview build, make sure you back up your important files and data. You can also use the Recovery options in Settings to go back to a previous version of Windows 10 if you encounter any problems with the preview build.

Windows 10 Build 18890 also introduces some changes to the Wi-Fi list in the network flyout. The new design no longer shows a warning for open networks, but instead uses an icon to emphasize the protection you get from using secured Wi-Fi networks. The per-network "open" or "secure" text is now moved to the details shown when you interact with a Wi-Fi network. This allows more networks to be shown in the list without scrolling.
Another change in this build is that Friendly Dates in File Explorer are no longer available. This feature was introduced in previous builds to show dates in a more natural and readable way, such as "Yesterday" or "Last week". However, based on user feedback, Microsoft has decided not to roll out Friendly Dates to users as part of the 19H1 release. Insiders will see this option go away starting from this build.
As usual, Windows 10 Build 18890 also comes with some known issues that you should be aware of before installing it. For example, there is an issue with older versions of anti-cheat software used with games that could cause PCs to crash. There is also an issue with some Realtek SD card readers that are not functioning properly. You can check the full list of known issues on the Windows Insider Blog or the Windows Insider Forum.
