Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.

Instruction is serializing, and causes a mandatory #VMEXIT under virtualization. Support for CPUID can be checked by toggling bit 21 of EFLAGS (EFLAGS.ID) – if this bit can be toggled, CPUID is present. Usually 3 [f] Intel Pentium, [g] AMD 5x86, [g] Cyrix 5x86, [h] IDT WinChip C6, Transmeta Crusoe, Rise mP6, NexGen Nx586, [i] UMC Green CPU ...
A keylogger running on the system will capture any typed passwords. [8] [3] A user with administrator privileges can install a new Security Support Provider (SSP). The new SSP will not be able to access stored password hashes, but will be able to capture all passwords after the SSP is installed. [8] [9]
It allowed the user name, domain name, and password hashes cached in memory by the Local Security Authority to be changed at runtime after a user was authenticated — this made it possible to 'pass the hash' using standard Windows applications, and thereby to undermine fundamental authentication mechanisms built into the operating system.
Hyper-V is a native hypervisor developed by Microsoft; it can create virtual machines on x86-64 systems running Windows. [1] It is included in Pro and Enterprise editions of Windows NT (since Windows 8) as an optional feature to be manually enabled. [2]
The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords.
