What's new

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.

Other updates for Insiders

Introducing Microsoft News Bar (Beta)

A few cool things about this app:

  • 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 Multiple Monitors.

Raw Image Extension now supports Canon CR3 format
