Microsoft has released the new Windows 10 Insider build 19557, for those in the Fast Ring. The new Build comes with changes to the Windows image and changes to diagnostic data. If you are participating in Microsoft's "Insider" program , you can download the Update by going to Settings -> Update & Security -> Windows Update.
The most important changes in the new Build are listed below:
Diagnostic data:
Microsoft made some changes to the diagnostic data settings in Windows 10. Now, the «basic» data will be called «necessary» , while the «all» option will become «additional». If a corporate user selects «additional», Microsoft gives you the right to decide which data is collected from your company.
New images:
Microsoft has also changed the icons for several programs such as File Explorer, OneDrive, Mail, Calendar, Your Phone as well as the desktop icon. In this build, Microsoft has released a new security image for Windows 10, which, in our opinion, looks much better than the previous one.
Cortana:
You can now say or ask Cortana more informal things like "Tell me a joke" or "rock paper scissors", and the like.
Additionally, there are also changes to the way the advanced startup operates, in order to improve the functionality of Ease of Access. Now, the advanced startup will boot directly into recovery mode.
For now, Microsoft continues the experiments on Windows 10 updates, extending the period until March.
