What is Windows Sandbox and How to Use?
In today’s digital world, it is very easy to run malware, disguised as a genuine product, or visit a malicious website thus compromising the security of your computer system. To avoid this potential danger, most users refrain from running apps or utilities from unknown sources. While this may improve your system security, it could also mean that you are missing some useful tools from legit but unpopular developers.
Fortunately, with the Windows Sandbox, users can test untrusted apps, utility or websites on an independent environment before installing in their main desktop environment. This article explores the new Windows Sandbox feature and using it to improve security within the Windows 10 environment.
What is Windows Sandbox and How Does it Benefit Users
Windows Sandbox is a new virtualization feature available beginning with Windows 10 1903 version (Windows 10 May 2019 Update). The feature allows admins and users to create a virtual and temporary clean OS imaged from the current system state, enabling them to test unknown applications without the risk of harming the underlying host. The Sandbox isolates the virtual desktop environment from your actual PC and destroys the state upon closing.
You can safely visit suspicious sites, download and install untrusted programs without transferring anything to the main installation. Moreover, Windows Sandbox offers the convenience of transferring files in and out the virtual machine, removing them out of the quarantine when you are certain about their safety.
Windows Sandbox Benefits
Although creating a virtual machine within your Windows 10 can serve the testing purpose, Windows Sandbox is more than just a safe testing zone.
- Windows 10 integration – The features ships with Windows 10 Pro and Enterprise (1903 version, thus no need to spend more time creating or downloading the virtual environment.
- Clean Installation – Windows Sandbox is an on-demand virtual machine that runs as a clean installation. After testing the programs, you only need to shut it down and it will dispose of everything, leaving no impact on your PC.
- Security – The tool uses hardware virtualization to implement kernel isolation.
- Efficiency – Windows Sandbox uses Virtual GPU, smart memory management and integrated kernel scheduler to run a virtual state, separate from your main system state.
- Performance – It is a lightweight virtual environment (about 100MB), optimized to book and run faster than traditional virtual desktop environments.
