Microsoft Officially Launches Windows Sandbox

Windows 10 19H1 will feature offer a native Sandbox

The feature, Windows Sandbox, will be available only on the Windows Pro and Enterprise editions.

InPrivate Desktop was first leaked back in August as an upcoming feature of Microsoft's Windows 10 operating system.

"Any software installed in Windows Sandbox stays only in the sandbox and can not affect your host". To start up quickly, the Sandbox simply boots up from a VM snapshot instead of going through the entire Windows boot process. This will allow Windows 10 users to run specific programs in an isolated environment that can not harm their data or otherwise interfere with the running of their PC.

There's a lot in build 18305, including improvements to Start, Fluent Design, and Cloud Clipboard, in addition to new features like Windows Sandbox.

Windows Sandbox is a strong move by Microsoft that will enhance endpoint security and reliability.

We're rather more onboard with the latter, so let's tell you about the new Windows Sandbox feature which is rolling out next year.

On December 17, 2018, Microsoft announced that the October 2018 Update for Windows 10 is available for a wider audience again. Although the obvious use case for the Sandbox is checking if a program is bad, it can also be used for testing if an application works correctly in a pristine Windows environment. Underneath, it uses Windows Containers tech and employs dynamic links to the host's system files on disk and in RAM. This means that if the sandbox has a low priority thread, it can be displaced by a higher priority thread from the host.

Windows Sandbox seems to take inspiration from Qubes OS, an Linux-based platform that allows multiple operating systems to exist on top of it as virtual machines in order to isolate various user tasks.

Using the Sandbox, you can open files, infect it will all sorts of scary malware, and then shut it down. You'll need to be a Windows Insider if you want to get your hands on it today, but Microsoft says it will roll out to all Windows 10 users "soon".

The sandbox also uses a new technology called "integrated scheduler", which allows the host to decide when the sandbox runs. It's just not necessary, thanks to OneDrive integration with Windows 10 and the Most Recently Used (MRU) document functionality in all Office applications. Normally, virtual machines are not able to access GPUs because they are isolated from the host system.
