Windows 10 Insider Preview build 18305.1000 (rs_prerelease) – build version under the code name 19H1, which is available to members of the Windows Insider program with the priority of receiving updates Early Access.
This assembly belongs to the RS_PRERELEASE development branch of the next major Windows 10 update, which is expected in spring (March-April) of 2019.
New in Windows 10 build 18305 (1903)
New build Windows 10 Insider Preview Build 18305 has received a large number of new features: Windows Sandbox, support for characters and kaomoji, automatic restart and authentication (ARSO) for corporate users. Also, improvements were received by the Start menu, Windows Security application, cloud clipboard, user authentication mechanisms, Task Manager, troubleshooting, Parameters application, and Windows Explorer.
This assembly simplifies the layout of the Start menu by default for new devices, new user accounts and for clean installations of Windows 10. The main differences are: one-column design, reduced top-level tiles and a separate customized version for corporate and educational users. If you upgrade to the new build, you will not see the layout changes, because Windows updates do not change your current view of the Start menu.
Microsoft describes the new feature of Windows Sandbox as “a new lightweight desktop environment for running applications in isolated space”. You can run executable files without worrying about the consequences or work with a clean installation of Windows, even without setting up a virtual machine. Any software installed in the Windows sandbox can only affect the sandbox and after closing the Windows Sandbox session, all files will be deleted. The feature will come with Windows 10 Pro and Windows 10 Enterprise.
When you click Windows +. or Windows +; the opening pop-up menu allows you not only to select regular emoticons, but also various symbols: punctuation, currency signs, geometric and mathematical symbols, Latin letters and Japanese Kaomoji. For the first time this feature appeared in build 18252, but now it has become available to all Windows insiders.
The cloud clipboard (Windows + V) received an updated, more compact interface. Since 90 percent of buffer objects are plain text, the design of the function has been optimized for text fragments. Now the user can immediately see more text entries without scrolling.
Login by phone number
Microsoft continues to adhere to its long-term strategy to completely abandon passwords, and this time the company added support for setting up authorization in the system by phone number using the appropriate account. Now you can receive codes via SMS to set up your account for the first time, and then use Windows Hello biometric authentication methods or a PIN code to log in to the system.
In addition, the Windows Hello PIN reset wizard has now received an updated web-interface design.
Creating a bootable ISO image
If you want to perform a clean installation of Windows 10 Insider Preview build 18317, then using the WZT-UUP service, you can download UUP files directly from the official Microsoft servers and automatically create a bootable ISO image using the following instructions:
Download the generated archive, unpack and run the file creatingISO.cmd.
Since this is a command line script, the Windows Defender SmartScreen filter will show a warning before starting – “Windows has protected your computer.” Click “Read More” and execute “Run anyway“. For security, you can always analyze the contents of the script manually before launching it.
Wait for the automatic downloading of UUP packages from official Microsoft servers and the creation of a bootable ISO image.
Use the generated ISO to install the latest version of Windows 10 Insider Preview.
