However, doing this has certain complexities. Currently, virtualized sites can't store persistent cookies, for example, because virtual machines get destroyed when the browser is closed. This may be acceptable for a locked-down enterprise environment, but it isn't a good fit for consumers.
There are also compatibility constraints. VBS installs the Hyper-V hypervisor. This requires a processor with hardware virtualization support, and it also requires I/O virtualization (such as Intel's VT-d) to protect against certain known attacks. This means that some systems in the wild won't support it. There are also software concerns; only one hypervisor can be installed at a time, which means that a machine that's running Hyper-V cannot also run VMware Workstation or Virtual Box, say, or software that uses virtualization behind the scenes, such as the Bluestacks Android-on-Windows software.
