A new Insider preview build of Windows 10 for the Fast ring that is bringing an exciting list of new features has been released to Windows Insiders. Windows 10 Build 19603 brings a new Microsoft News Bar app, which is redesigned from Microsoft News app, Canon CR3 RAW image format support, Windows Subsystem for Linux (WSL) integration in Fie Explorer, and User cleanup recommendations in Storage Settings.
Windows 10 Insider Preview Build 19603 is released to Fast ring, which means it’s an independent test build from Active Development Builds branch of Windows 10, and showcases new features that may eventually show up in future public Windows 10 releases, even though these features are no longer matched to a specific Windows 10 release. In contrast, Slow ring of Windows Insider will publish upcoming Windows 10 Feature Update release, which is currently slated to be Windows 10 2004 (May 2020 Update) Build 19041.
The changelog for Windows 10 Build 19603 as provided by Microsoft:
- File Explorer Integration in the Windows Subsystem for Linux (WSL)
If you have WSL installed and open up File Explorer, you can now easily get to Linux files from your left-hand navigation pane in File Explorer. Selecting the Linux icon will show you a view of all your distros, and selecting those will place you in the Linux root file system for that distro.
- User cleanup recommendations in the Storage Settings
Free up disk space with this Storage Settings feature that gathers unused files and apps from 4 sections: Temporary files, Large or unused files, Files synced to the cloud and Unused apps, so you can digitally cleanse your device.
- Microsoft News Bar
News Bar brings you the latest news from the Microsoft News network of over 4,500 publishers across the globe. Features of News Bar include:
- Stories are continuously updated throughout the day.
- Hover for quick access or select to get the full story.
- Provides News and Stocks today, with Weather and Sports coming in the future.
- Highly configurable, allowing you to place it on the side you want it, change the background color, change the appearance of what is shown, and which country you want the news from.
- Supports dark and light themes in Windows 10.
- Supports Multiple Monitors.
If you’re in the U.S., you can download the News Bar from Microsoft Store.
- Raw Image Extension now supports Canon CR3 format
The latest version of the extension (1.0.307610.0) that’s now released to Windows Insiders includes support for Canon CR3 files (though not GoPro raw camera format .GPR), increased camera support, and several bug fixes.
General changes & improvements

- Fixed an issue that led to inaccurate size estimates for disk cleanup when the option to clean up old Windows installation files was included.
- Fixed an issue where Storage settings would say the option to clean old Windows installation files wasn’t available, because it had been automatically removed after a certain number of days, when actually you had manually selected to remove it.
- Fixed an issue that could result in Settings crashing when navigating to Network & Internet for some Insiders.
- Fixed an issue where you would see a notification from the Shared Experiences page saying your account needed fixing, however the Fix Now option on the page wouldn’t work.

- The Documents section under Privacy has a broken icon (just a rectangle).

- App icons in the taskbar are having rendering issues, including defaulting to the .exe icon.
- The battery icon on the lock screen always shows close to empty, regardless of actual battery levels.
- IIS configuration being set to default after taking a new build. You will need to back up your IIS configuration and restore it after the new build is installed successfully.
- Language packs may fail to install on this build. This is most impactful for anyone who chooses to reset their PC – the language packs you have prior to upgrading will persist. Anyone impact by this may notice some parts of the UI don’t display in your preferred language.
- Quickly switching between WSL distros using the file explorer integration could cause a transient access error.
