Build 10565 for PC available to Windows insiders

A few minutes ago, Microsoft announced another build for the PC using the Windows Insider program - Build 10565 (available in Fast ring).

Immediately about the problems

• Insiders from Russia and Turkey until the end of the week will not be available for download language packs.
• The search does not yet work in regions where Cortana is not supported.
• Xbox will consume 1 GB of RAM if win32 games are installed on the PC.
• Support for WebM and VP9 is cut from the assembly, will be returned in the future.
• On some devices with a small screen, such as Dell Venue Pro 8, the installation of a new assembly may end with BSOD - it is treated by rolling back to the previous assembly.

Bugs also fix:

• Fixed background playback of some music applications in minimized mode.
• Fixed display of context menus, which, according to insiders, seemed too cumbersome.
• Now you can pin contacts from the People application to the Start menu.
• Fixed a problem with bifurcation of some applications on the taskbar when they are fixed on it.
• The operation of hiding desktop icons through the context menu has been fixed.
• Fixed the problem of automatic updating of applications in the Windows Store.

What's new:

• Skype messages, calls and videos are new universal applications (recently the standard Messages application in Windows 10 Mobile has also been updated to an application with Skype integration). That is, now, Skype is integrated into the system, it works reasonably well (at least on mobile windows), but Microsoft warns that there may be errors.
• Microsoft Edge: finally added synchronization of favorites and reading list + previews of open tabs appeared.

• Cortana: Learned to understand handwritten notes. I also learned how to analyze your mail for movie tickets and other entertainment - two hours before the start it will notify you of an upcoming event.
• UI / UX: context menu improvements, color added to window titles (can be disabled in Options-> Personalization-> Colors). Added several new icons to the device manager + made a new icon for the registry editor.

• Printer: now the default printer will be the last printer used, it will be disabled in the settings.

Now when you install Windows 10 Insider Preview or when you manually activate it, you can enter the key for Windows 7, Windows 8, and Windows 8.1. Currently, this feature only works for current versions of Windows 10 Insider Preview and after successful testing will be available to ordinary users.
