Windows 10 build 10051 is leaked, features changes to core apps

Yesterday, a new build of the Windows 10 operating system leaked to the Internet. Although the leaked build is just two builds newer than the latest official public build 10049, which was recently released for Windows Insiders, this new build features several notable changes which build 10049 does not include.


In Windows 10 build 10051, Calendar and Mail apps have an updated user interface. Here is how the Calendar app looks like:

Windows 10 build 10051 was sent to Microsoft's partners several days ago. Due to that, more details about the changes are available. According to the document below, the file picker that was used for Modern apps in Windows 8.1 has been dropped in favor of the more traditional file dialog box. See the complete change log below: changelog 10051 Well, while Windows 10 build 10051 does not come with any other radically new features and options. It might be interesting for enthusiasts to play with. Credits: Neowin.
