Last Thursday, Microsoft added a few new known issues to the changelog for Windows 10 Insider Preview build 19592, also saying that there wouldn't be a new build that week. That means that it's been two weeks since there's been a new Windows 10 Insider Preview in the Fast ring, and we're finally getting a new one today.
Today's Windows 10 Insider Preview is build 19603, and as usual, it's mostly about fixes. Since the Fast ring is in a perpetual development branch, there's no "big bang" feature update release.
There are a couple of improvements though, such as File Explorer support for the Windows Subsystem for Linux. Here's the full changelog:
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!
We’ve 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.
As usual, Microsoft noted some other improvements, which aren't specific to this build. The Microsoft News Bar (Beta) app is available now, and it provides news stories in various formats on your PC. Also, the Raw Image Extension now supports Canon's CR3 format.
