No.1: How to Crack Windows 10 Password with Windows 10 Password Cracker
The first way I'd like to introduce is to hack Windows 10 password with Windows 10 Password Recovery Tool. The reason why I highlight this tool is because:
1. This software has four editions, which gives you a lot of choices and convenience in cracking Windows 10 password;
2. You are allowed to reset/remove/recover password and even create a new admin account. Very powerful;
3. Adapt to Local account password, Microsoft account password, and even domain password.
Steps on Hacking Windows 10 Local and Microsoft account password with password hacker:
Download the full version of Windows 10 password recovery tool and install it into an available computer.
Insert a blank USB flash drive into the PC where you install the cracker and then launch it. Tick "USB Flash Drive: option and click on "Burn" (default ISO image or Advanced Recovery Wizard).
After your PC boots by the burned disk, you can see the interface of this cracker. Just follow the instructions to hack Windows 10 password.
No.2: Crack Windows Local Password with Password Reset Disk
If you have created a password reset disk for your Windows 10 login account before you lose access, you can easily bypass Windows 10 administrator password without third party software (other local user passwords are available as well).
Boot your PC and type anything in the password box.
When you see the "Reset Password" and click it, the password reset wizard will appear, insert your password reset disk into your Windows 10 PC. And click the prompt.
Password Reset Wizard shows up. Just follow the steps to reset your forgotten Windows 10 login password.
No.3: Windows 10 Password Crack via Command Prompt
Command Prompt (command shell or cmd.exe) is another free application in Windows operating system that can help you when you forgot Windows 10 password. Just run the application.
Note: To use Command Prompt to reset password, you need to have another account to login as an administrator.
Click "Start" and type "command" in the search box.
Right-click on Command Prompt and "Run as administrator".
Type "net user Username New password" in Command Prompt as below. Hit Enter.
All right, all points have been listed here. From my own perspective, I prefer using Windows 10 password recovery tool to break Windows 10 Microsoft account password and local user account password. It's more easy and convenient for you, morever, it's appropriate for any situation.

Definition - What does Artificial Intelligence (AI)mean?
Artificial intelligence (AI) is an area of computer science that emphasizes the creation of intelligent machines that work and react like humans. Some of the activities computers with artificial intelligence are designed for include:
Artificial intelligence is a branch of computer science that aims to create intelligent machines. It has become an essential part of the technology industry.
Research associated with artificial intelligence is highly technical and specialized. The core problems of artificial intelligence include programming computers for certain traits such as:
Knowledge
Reasoning
Problem solving
Perception
Learning
Planning
Ability to manipulate and move objects
Knowledge engineering is a core part of AI research. Machines can often act and react like humans only if they have abundant information relating to the world. Artificial intelligence must have access to objects, categories, properties and relations between all of them to implement knowledge engineering. Initiating common sense, reasoning and problem-solving power in machines is a difficult and tedious approach.
Machine learning is another core part of AI. Learning without any kind of supervision requires an ability to identify patterns in streams of inputs, whereas learning with adequate supervision involves classification and numerical regressions. Classification determines the category an object belongs to and regression deals with obtaining a set of numerical input or output examples, thereby discovering functions enabling the generation of suitable outputs from respective inputs. Mathematical analysis of machine learning algorithms and their performance is a well-defined branch of theoretical computer science often referred to as computational learning theory.
Machine perception deals with the capability to use sensory inputs to deduce the different aspects of the world, while computer vision is the power to analyze visual inputs with a few sub-problems such as facial, object and gesture recognition.
Robotics is also a major field related to AI. Robots require intelligence to handle tasks such as object manipulation and navigation, along with sub-problems of localization, motion planning and mapping
Computer being a versatile machine can process different types of data. so to work with these data types we need different type of devices which can help us to enter such data types in the computer and to receive their outputs as well in this chapter we will cover many such devices like keyboard, mouse, joystick, light pen, printer, speaker, etc. That can be used with the computer.
What is computer?
Children you know that computer is a data processing machine and it needs user’s instructions to perform any job. After processing the raw facts (called data), it produces useful information for the user. But how do you give data and instructions to the computer and how it can return the useful information to you.
To do all these, different types of input and output devices can be connected with the computer.
Input Devices
The devices which are used to give data and instructions to the computer are called Input Devices. Various types of input devices can be used with the computer depending upon the type of data you want to enter in the computer, e.g., keyboard, mouse, joystick, light pen, etc.
Think and Answer
Which of your sense organs work like input devices?
Keyboard
It is the most commonly used input device. It is used to enter data and instructions directly into the computer. There are 104 buttons on the keyboard which are called keys.
Did you Know?
The keyboard was invented 134 years ago by Christopher L. Sholes.
Mouse
Mouse is another input device which is commonly found connected with the computers. It is basically a pointing device which works on the principle of Point and Click. When the mouse is moved on the mouse pad, a light beam underneath reflect to give motion to the pointer on the screen. The mouse is used in windows based programs, where the user can run the commands by pointing the objects with the help of pointer and clicking the buttons on the mouse. We also use mouse for drawing in paint and kid pix.
Most of the latest mouses, these days, include a wheel in the middle of two buttons that help us to scroll through documents more easily. we use our forefinger to move the wheel to scroll up or down in a document. Optical mouse uses red light to track the movement of mouse for moving the pointer on the computer screen. This type of mouse is more accurate and reliable than the traditional mouse.
Nowadays cordless mouse is very popular. it dose not have wires. it either uses Bluetooth technology to sends the data through the air to a receiver, usually plugged in USB port of the computer.
Joystick and Game-pad
Joystick and game-pad are also input devices which are also input devices which are used to control the movement of object on the screen. Just like mouse, these are also pointing devices. Mostly they are used for playing games on the computer.
The joystick has a vertical stick with a track ball at its bottom. While playing the games on the computer, the user needs to move the objects quickly on the screen. With the movement of this vertical stick the objects can be moved in all the directions easily.
A game-pad is a type of game controller held in two hands, where the fingers (especially thumbs)are used to provide input by pressing buttons on it. It is also known as Control Pad.
Think and Answer
Have you seen joystick in any other machine?
Light Pen
Light pen is another pointing type input device. It is a pen shaped device which can be used by directly pointing the objects on the screen. It can also be used for making drawings directly on the monitor screen.
Scanner
We can store pictures, photographs, diagrams into the computer with the help of scanner. The scanner reads the image and saves it in the computer as a file.
Touchscreen
Touchscreen is a special computer screen that takes the input by sensing the touch of a human finger, gloved hand, stylus, pen or any other pointing device. The user gives instructions to the computer just by touching the screen.
Microphone
This is an input device which is used to record sound or voice into the computer system. You can store voice data in the computer by speaking in front of this device.
Trackball
A trackball is similar to a mouse but is mounted in a fixed position. The user spins the ball with fingers to move the pointer on the screen.
A Trackball technology was used in earlier laptop computer which is now replaced with track-pad.
Think and Answer
Name any two input devices you commonly use while working on computer.
Output Devices
The devices which are used to display the results or information are called Output Devices. You can view the output on the monitor or you can print it on a paper using a printer. Monitor and the printer are the commonly used output devices.
Monitor
This is the most common output device connected with the computer to display the processed information. It looks like a TV and is also know as VDU(Visual Display Unit). Pictures are displayed by using a large number of very small dots on screen called pixels. The number of pixels that a monitor can show on its screen is referred to as the resolution of the screen.
The two commonly used monitor types are:
Cathode Ray Tube(CRT)Monitor
Liquid crystal Display(LCD)Monitor
Add to Your knowledge
LCD uses very small amount of electricity as compound to CRT.
The output produced on the screen is called Soft Copy Output because it cannot be retained for a long time.
Nowadays LCD monitors are more popular as their sharp picture quality. They are light weighted and flat screen monitors.
Printer
This is an important output device of the computer system. It gives a printed output of the results that appears on the monitor screen. Printed output is also called Hard Copy output because unlike monitor, this output can be preserved even if the computer is switched off.
Think and Answer
What kind of printer do you use in your school?
Printers are of different types. On the basis of their printing techniques, printers are grouped as follows:
1.Character printer
2.Line printer
3.Page printer
Character Printer
Character printer prints one character at a time; it prints at the speed of around 30 to 600 characters per second.
Dot Matrix printer is an example of a character printer.
Dot Matrix Printer
This type of printer works like a typewriter. It creates an impression on the paper by pressing the end of pins fixed in its print heads, against an inked ribbon. This printer is noisy with a low print quality. Its speed is measured in CPS(Characters Per Second).
Line Printer
This is high speed printer that prints one line at a time. It is used when large quantity of output is required as it produces the quick output. Examples of a Line printer are Drum printer and the Chain printer. The noise level of these printers is high and speed ranges from 200 to 2000 LPM(Lines Per Minute).
Page Printer
Page Printer prints a whole page at a time. Examples of these printers are inkjet printer or a Line printer because it has to store each page in memory before printing it.
Inkjet Printer
This type of printer prints by spraying tiny ink droplets on the paper. It can print in both, color as well as black and white. The print quality of this printer is better than that of Dot Matrix Printer and it prints without making any noise. Its speed is measured in PPM(Pages Per Minute).
Add to your knowledge
The most commonly used printers are:Dot matrix,inkjet and Laser printers.
Laser printer
In this type of printer, laser beam technology is used to print the text or graphics on the paper. The speed of this printer is very fast and it gives out very fine quality prints. It’s speed is also measured in PPM.
Speaker
Speakers are categorised as output devices. These are used to listen to the music and sounds played by the computer. Normally they come in a pair and have different shapes and sizes.
Plotter
We can get the print of a photograph, drawing, image stored in the computer, by using a plotter. It is an output device which provides a high quality of printed output. It is generally used by engineers and architects.
So you're shopping for a new computer in an electronics store and you're trying to make sense of the technical specifications. One computer that looks pretty cool has a 64-bit quad-core Intel i7 3.5 GHz processor. Sounds impressive, but what does it really mean?
The last computer you bought a few years ago had a sticker on it that said Pentium 4, but you don't remember the details. The computer was getting sort of slow, but why would you need a 64-bit quad-core? Why exactly is this better than the processor in your old computer? To understand what the specifications mean, we first have to look at how the processor is designed and how it functions.
Definitions
The central processing unit (CPU) of a computer is a piece of hardware that carries out the instructions of a computer program. It performs the basic arithmetical, logical, and input/output operations of a computer system. The CPU is like the brains of the computer - every instruction, no matter how simple, has to go through the CPU. So let's say you press the letter 'k' on your keyboard and it appears on the screen - the CPU of your computer is what makes this possible. The CPU is sometimes also referred to as the central processor unit, or processor for short. So when you are looking at the specifications of a computer at your local electronics store, it typically refers to the CPU as the processor.
When we start to look at the various components of a CPU and how they function, remember that this is all about speed. When we use a computer, we want the instructions to be carried out very fast. As the instructions become more complicated (for example, creating a 3D animation or editing a video file), we demand more from the CPU. Thus, the technological advances we have seen in processor technology have largely been driven by the need for speed.
Components
A typical CPU has a number of components. The first is the arithmetic logic unit (ALU), which performs simple arithmetic and logical operations. Second is the control unit (CU), which manages the various components of the computer. It reads and interprets instructions from memory and transforms them into a series of signals to activate other parts of the computer. The control unit calls upon the arithmetic logic unit to perform the necessary calculations.
Third is the cache, which serves as high-speed memory where instructions can be copied to and retrieved. Early CPUs consisted of many separate components, but since the 1970s, they have been constructed as a single integrated unit called a microprocessor. As such, a CPU is a specific type of microprocessor. The individual components of a CPU have become so integrated that you can't even recognize them from the outside. This CPU is about two inches by two inches in size.
CPUs are located on the motherboard. Motherboards have a socket for this, which is specific for a certain type of processor. A CPU gets very hot and therefore needs its own cooling system in the form of a heat sink and/or fan.
The ALU is where the calculations occur, but how do these calculations actually get carried out? To a computer, the world consists of zeros and ones. Inside a processor, we can store zeros and ones using transistors. These are microscopic switches that control the flow of electricity depending on whether the switch is on or off. So the transistor contains binary information: a one if a current passes through and a zero if a current does not pass through.
Transistors are located on a very thin slice of silicon. A single silicon chip can contain thousands of transistors. A single CPU contains a large number of chips. Combined, these only cover about a square inch or so. In a modern CPU, however, that square inch can hold several hundred million transistors - the very latest high-end CPUs have over one billion! Calculations are performed by signals turning on or off different combinations of transistors. And more transistors means more calculations. You may be interested to know that the material, silicon, used in chips is what gave the Silicon Valley region of California its name.
A simple detail about password cracking tools from the wiki. In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system. A standard approach (brute-force attack) is to try guesses repeatedly for the password and check them against an available cryptographic hash of the password. Password cracker is not hacking a password; this software only recovers your password. Got it? So don’t use against someone’s system or illegally.
The other purposes of password cracking tools might be to help a user recover a forgotten password of a system or any software. But in the world of hacking, hackers are using such a tools to break or crack the stolen password hashes of a database. Or using them to hack the wireless network and crack the passwords. So hope you completely understand the primary purpose of password cracking tools.

RainbowCrack
2. RainbowCrack
The RainbowCrack password cracking tools is a general propose implementation of Philippe Oechslin’s faster time-memory trade-off technique. It cracks hashes with rainbow tables. RainbowCrack uses time-memory tradeoff algorithm to crack hashes. It differs from brute force hash crackers.
A brute force hash cracker generates all possible plaintexts and compute the corresponding hashes on the fly, then compare the hashes with the hash to be cracked. Once a match is found, the plaintext is found. If all possible plaintexts are tested, and no match is found, the plaintext is not found. With this type of hash cracking, all intermediate computation results are discarded.
