Microsoft seems to have opened up shop again with Windows 10 preview builds. The Windows program Insiders is back online with a new build. 
Windows 10 build 10525 is only available to those enrolled in the pro fast ringletterWindows Insider and those interested can download it immediately.
The new version comes with more color options, which Microsoft says will help you customize the surface work you as you wish.
The feature is disabled by default, but you can enable it from Settings - Customize - Colors.
At the same time, Microsoft reports that it has made significant improvements in management μνήμηs, a new feature that helps Windows 10 manage running processes in a more efficient way, which helps improve performance and reduce the impact on system performance.
If you are registered with Windows Insiders the update will come to you automatically. If you are not you will need to register your computer to receive preview builds. To do this, go to Settings - Update & Security - Advanced Options and enable Get Insider Builds.
If you're on a computer you're working on, you'd better avoid previewing.
