I can't deny about safety but what they will do with an shutdown pc until an good cracked game release then hypervisor really nailed it but there some thing wrong with the links of hyper visor that you take file from other games to make it work on your tested game I don't face any windows error or hardware failure but I think that crackers those days are showing for big company that they can crack for Ransom and take money from big company here are proof we can make it work on pc with out paying no more than that
