iCore Virtual Accounts is free download OS level virtualization (container-based virtualization) for Microsoft Windows

that runs on top of the existing hardware
and operating system
. It allows the user to create multiple virtual
"accounts" (virtual machines) that can be easily created or deleted without affecting each others’ state or the state of the core
operating system.
Such machines create and capture the output of a virtual "account" inside a virtual disk. Only the changes to specific files and programs accessible to that virtual account will be stored in the virtual disk attached to that account. One can install programs inside it that will be sandbox
ed from the entire system, existing only inside the virtual disk. Each virtual account has full dedicated PC functionality with its own processes, files, and applications. This is accomplished by using a virtualization layer in the kernel of the host OS.
In contrast, programs accessible to all users of the computer will be usable in the virtual accounts without taking up space there, but the settings and bookmarks for the users of that account will stay inside the virtual disk.
, with its own registry, process, files, services and so on.
Software from vendors can run inside a container without modification.
