<p>According to Microsoft, this is the last major build for Insiders this year and only further Cumulative Updates will be released as needed.</p>
<p>This update comes with a huge changelog bringing many new features to the latest Windows 10 operating system.</p>
<p>One of the new features worth mentioning is a <strong>Windows Sandbox mode</strong>, which basically is a lightweight desktop environment where you can run apps in isolated mode.</p>
<p>Imagine Windows Sandbox mode like a lightweight virtual machine where you can run and test untrusted software downloaded from the internet without the fear of infecting your device or in worst case losing your data.</p>
<p>Any software that is installed in the Sandbox mode, stays in it and cannot affect your host/Windows 10 installation in any way. Once closed, all software in the Sandbox mode gets permanently deleted.</p>
<p>Sandbox is a part of <strong>Windows 10 Pro</strong> and <strong>Enterprise</strong> versions and there is no need for additional VHD downloads.</p>
<p>Each time you run Windows Sandbox mode it runs as a clean Windows installation and nothing persists on the device as all changes are discarded once the application is closed.</p>
<p>Windows Sandbox is also very secure as it uses Microsoft Hypervisor or hardware-based virtualization for kernel isolation. Therefore, Sandbox mode is completely isolated from your host Windows installation.</p>
<p>It requires at least <strong>4GB of RAM</strong>, <strong>1GB</strong> of free disk space and virtualization has to be enabled in BIOS.</p>
<p>To enable the Windows Sandbox mode, from the Start menu run <strong>Add or remove programs</strong> and n the right pane click on <strong>Programs and Features</strong>.</p>
<p>In the left pane select <strong>Turn Windows features on or off</strong>.</p>
<p>Scroll down and check the <strong>Windows Sandbox</strong> checkbox.</p>
<p>Restart your machine.</p>
<p>Along with the Windows Sandbox mode, Windows Security app also gets updated features like New Protection History experience and Tamper protection. <strong>Tamper protection</strong> is a new setting for Windows Defender Antivirus that prevents other services from tampering with important security features.</p>
<p>Other new features include a new look for <strong>Clipboard history</strong>, <strong>password-less Microsoft accounts</strong>, <strong>recommended troubleshooting</strong>, <strong>shadows</strong>, many updates to <strong>File Explorer</strong> etc.</p>
