Today Microsoft released Windows 10 Insider Preview Build 19603 to Windows Insiders in the Fast ring.

What’s new in Build 19603

File Explorer Integration in the Windows Subsystem for Linux (WSL)

If you have WSL installed and open up File Explorer, you’ll see a familiar face.

You’ve had had the ability to access your Linux files since Windows 1903, but now you can easily get to them 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 Storage Settings

Free up disk space with this Storage Settings feature that gathers unused files and apps so you can digitally cleanse your device.

Windows cannot predict whether you want to delete personal files, uninstall apps, or remove local copies of files synced to the cloud. With this tool, all the content is gathered in one page and removable by you with a few clicks.

Other updates for Insiders

Raw Image Extension now supports Canon CR3 format

Support for Canon’s latest CR3 raw format has been a popular request ever since the Raw Image Extension was announced and then released to the store in 2019. If you’ve been waiting for this feature, Microsoft has good news for you. The latest version of the extension (1.0.307610.0) that’s now flighting to Windows Insiders includes support for Canon CR3 files, increased camera support, and several bug fixes.

Check out this libraw.org documentation for a complete list of supported cameras. Please note that GoPro raw camera format (.GPR) is still not supported.

Here is how to try this out:

1. If you have a previous version of the extension installed on your device, first you should confirm if your current installation has been automatically updated to the latest version (version 1.0.307610.0). Use these steps:
   1. Go to Settings > Apps.
   2. Search for and select Raw Image Extension.
   3. Select Advanced options from under the name of the extension.
   4. If the displayed version number on the Advanced options page is 1.0.307610.0 or later, then you are up to date.
2. Otherwise, search for Raw Image Extension from the Store app to go the app page.
3. If you’d previously installed the app on your device, the update should start automatically.
4. If not, select the Update button or if the app wasn’t already installed on the device, select Get, followed by the Install

Note: This version is currently only available to Windows Insiders.

Microsoft would love to get your feedback. Please send your feedback through Feedback Hub under the Devices and Drivers > Video Playback category.

Known issues

• Microsoft are aware Narrator and NVDA users that seek the latest release of Microsoft Edge based on Chromium may experience some difficulty when navigating and reading certain web content. Narrator, NVDA and the Edge teams are aware of these issues. Users of legacy Microsoft Edge will not be affected. NVAccess has released a NVDA 2019.3 that resolves the known issue with Edge.
• Microsoft is looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
• The Documents section under Privacy has a broken icon (just a rectangle).
• Sticky Notes windows can’t be moved on the desktop. As a workaround, when you set focus to Sticky Notes, press Alt + Space. This will bring up a menu that contains a Move option. Select it, then use either the arrow keys or the mouse to move the window.
• Microsoft is investigating reports that app icons in the taskbar are having rendering issues, including defaulting to the .exe icon.
• Microsoft is investigating reports that the battery icon on the lock screen always shows close to empty, regardless of actual battery levels.
• Microsoft is investigating reports of 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.

Windows 10 Insiders in the Fast Ring can download the update by Checking for Updates in Settings.
