Last August, the first signs appeared that Microsoft is planning a sandbox mode for Windows 10. This will be a closed environment where untrusted applications can run and malicious code will not infect the system. Microsoft has now confirmed in a blog post, that Windows 10 is getting such a feature. The "Windows Sandbox" will be introduced with the next update 19H1, but only for the versions Windows 10 Pro and Enterprise.
As already suspected, the Windows Sandbox is aimed at users who frequently work with software that is potentially dangerous and that can compromise a system. Now it is known that the Windows Sandbox is based on the technologies of Windows Containers and can be installed as a feature. After installation, a sandbox can be accessed from the start menu, executable files are started by copying and pasting in the sandbox. When the Windows Sandbox gets closed, it will be reset to its original state.
The 64-bit version of Windows 10 is required to use the sandbox. At least 2 CPU cores, 4 GByte RAM and 1 GByte free hard disk space must be available; however, 4 cores, 8 GByte RAM and hyperthreading are recommended. For the first time this technology will probably be delivered with build 16301 of Windows 10 and is only available for participants of the Windows Insider program.
