Microsoft has described the InPrivate Desktop feature as a “throwaway sandbox for secure, one-time execution of untrusted software,” reports Bleeping Computer. The upcoming InPrivate Desktop feature has also been described as “an inbox, speedy VM (virtual machine) that is recycled when you close the app.” For those unaware, Sandbox is a security mechanism for separating running programs, usually in an effort to mitigate system failures or software vulnerabilities from spreading. It is often used to execute untested or untrusted programs or code, possibly from unverified or untrusted third parties, suppliers, users or websites, without risking harm to the host machine or operating system. It appears that Microsoft is planning to strengthen the Windows Defender on Windows 10 with native sandbox support and it is looking to target Windows 10 Enterprise starting with build 17718 for all branches. The ‘InPrivate Desktop’ requires at least 4GB of RAM, 5GB of free disk space, 2 CPU cores, and CPU virtualization enabled in the BIOS, and hypervisor capabilities enabled in the BIOS. See the reproduced image below for more information. Microsoft is yet to comment on the new feature. With Windows 10 “Redstone (RS5) expected to roll out to mainstream users in October 2018 or so, it is unlikely that the InPrivate Desktop feature will make into RS5. However, there may be chances of it getting featured in the next release for Windows 10, codenamed “19H1.”
