This feature has the basic function of virtual machine. Applications installed and running on Windows Sandbox will not affect the hard drive or Windows operations. Windows Sandbox can check for active applications that interfere with or sabotage the operation of the operating system. This helps protect you, and helps you decide whether to run on the real operating system or not. Besides, it helps you increase information protection when surfing the web.
Common examples is when you download Keygen or Path from the Internet. You just need to Copy the Keygen into SandBox to get the Key and then turn off SandBox. If the Keygen has a virus attached, Windows will not be affected
Windows Sandbox has the following basic features:
- As part of Windows: Has all the basic features of Windows 10 Pro and Enterprise. You do not need to use additional VHD.
- Pristine: Windows Sandbox operates independently of the operating system. You have an additional virtual Windows 10 in real Windows 10.
- Disposable: When you close the application in Sanbbox everything will be deleted.
- Doesn’t take up a lot of resources: Hardware-based virtualization to isolate the kernel, based on Microsoft’s hypervisor to run a separate kernel, isolating Windows Sandbox from the real machine.
- Effective: Integrated kernel, intelligent memory management and virtual GPU.
