The just just released Windows 10 preview build 10525 is now available to download for members of the Windows Insiders program on the Fast ring, but they should be aware there are a few known issues with this build.
The small issues list was posted by Microsoft's Windows Insider head Gabriel Aul:
- Mobile hotspot doesn't work in this build. When sharing the Internet from your device with mobile broadband using Mobile Hotspot, it will fail to get a valid IP address from your device and will show no internet access.
- An update to Movies & TV application from the Store will be required to fix an issue with video playback.
- Optional languages packs will not be available during the initial launch of this flight, it will be available later this week.
