Windows 10 Insider Preview build 20211 is now available to Windows Insiders in the Dev channel, and it actually has a few new features.
Two, in fact:
Linux disk support. If you’re using Windows Subsystem for Linux 2.0, you can now attach an external disk drive to your PC that is formatted using a file system that Windows 10 doesn’t natively understand, but Linux does—like ext2—and it will work normally, both from within WSL 2.0 and with File Explorer. This also works with internal disks, so it can help those who dual-boot between Windows 10 and Linux. You can learn more about this feature here.
Default apps improvements. Way the F back in April, Microsoft released a Fast ring (now Dev channel) build that added the ability to search when setting a default in Settings > Apps > Default apps > Choose default apps by file type/Choose default apps by protocol/Set defaults by app. The problem is that this feature, like way too many features, was A/B tested until now. So now it’s available to everyone, and it only took 6 months! I don’t even know why I complain about this stuff.
And that’s about it.
