Windows 10 Technical Preview

WINDOWS 10

Microsoft Advance Operating System

Microsoft, instead of launching Windows 9, has launched Preview of Windows 10 Operating System. In this OS various new features are added. This new operating system will be available in market by middle of 2015. Lets know whats new you will be getting in Windows 10.

You can download the ISO file for x32-bit and x64-bit version here.
Download link 1(32-bit (x86))
Download link 2(64-bit (x64))

It was hoped from last few days, Microsoft would launch Windows 9 as its new Operating System. But recently company has launched Windows 10 Preview instead of Windows 9. Microsoft launched Windows 8 operating system about 2 years back, but it could not get much success. Now Windows 10 is designed in such a way that it can run on mobile phones, tablets and personal computers easily. Yet company has launched Preview of new OS, it is expected that it will be available in market by July 2015. The new OS is built with various features which users were missing in Windows 8. From phones to gaming console, it can run on different devices.

START MENU RETURNS

In the new OS you will be getting Start Menu again. Actually, Microsoft removed Start Menu in Windows 8, but users didn't like this change. This time Microsoft took a U-turn and added Start Menu in its new OS again. Similar to Windows 7, Start Menu is given on bottom-left corner on desktop in Windows 10. Users will get Touch experience  like Windows 8.1 operating system. Instead, users will also be having option to give similar look as that of windows 7 to the new OS. Actually, Windows 10 is a combination of classic look of Windows 7 and modern user interface. In this new OS you can also change the layout.

UNIVERSAL APPS

Microsoft's new OS will also supports apps. Means users of Windows 10 Operating System can use all the apps of Windows store. These apps will also run on your desktop. You can also re-size these apps as per your choice. Besides this, new OS will also support older apps available on app store. Important functions can be accessed with Context Menu. Generally, the meaning of Windows Universal App is that all your apps can run on Windows 10 devices(desktop, phones and gaming console).

VIRTUAL DESKTOP

Microsoft has given an option of Virtual Desktop for Enterprises and Power users. You can switch different desktop as per your need with the help of Virtual Desktop. This will appear very similar to Virtual Desktop. Uses can have different desktops for different projects and file according to their convenience. This feature is in-built in Windows 10. Further, you can have overview of all running apps with the help of task-view and can move to virtual desktop and manage them easily. This is like adding more screens to your phone or tablet which can be viewed by swiping.

TASK VIEW

To improve multitasking in this new OS, Task-View Button ( alt-tab) is given. Task-View button is integrated on taskbar and can be used for switching to different apps on Virtual Desktop. Diminished preview of all the open aaps can be seen together.

CONTINUUM

This is he most interesting feature of Windows 10. This feature is for 2 in 1 devices. Actually, Continuum feature means that the user interface of new OS will change automatically according to the device. For example, suppose you are using a Hybrid Laptop-Tablet then you will be having standard desktop, but as soon as you unplug the keyboard, it will switch to Tablet mode. This time it has come up with Touch Button.

NO METRO AAPS

Windows 10 also doesn't have large tiles on Home Screen like other version of Windows. You can manage your items or can apply a background picture of your choice. You can switch from Tablet mode to Touch Screen mode without  keyboard and mouse. The Charms Bars of Windows 8 haven't been removed completely. Instead, these are improved. Windows 8 users, who are already familiar with this feature can further use it.

IMPROVED SNAP

Snap function has been improved in Windows 10. With this feature windows can be tiled horizontally and vertically. Snap Assist feature works according to you choice. If you want, you can snap windows into new screen or tile.

HIDE METRO INTERFACE

It is not clear yet, has the Metro Interface been completely removed or not. Actually this is a better option for Hybrid, but while talking about Desktop, Microsoft has given a Check Box at its place  in which 'Never Show Me The Metro Interface' option will be there.

EASY SHUTDOWN

Windows 8 users were waiting for an easy Shutdown feature. To Shutdown PC in Windows 8 users had to go to Charms firstly then Log off and then finally Shutdown. Now Windows 10 has given a much better Shutdown function. You will be able to see Shutdown option just by pressing alt+f4.

UNIVERSAL SEARCH

Universal Search function is given in Windows 10. This option works for both searching PC and Web. Now you don't have to go to browser for searching net. If you have searched something in Search option of Start Menu, it will not only show the search results of the aaps and files existing on your commuter but also give search results from internet. Microsoft's Universal Search is somewhat similar to Apple OS X.

Samsung Galaxy Alpha

Samsung has just launched a new Smartphone Galaxy Alpha with Metallic frame which is similar to Samsung Galaxy Note 4.  The Galaxy Alpha represents a new standard for smartphone design. This is Samsung's slimmest (6.7 mm) smartphone ever and this  is the first Galaxy to have a metallic frame around its edges. This device is powered by Exynos 5 Octa 5430 chipset, Quad-Core 1.8 GHz Cortex-A15 & Quad-Core 1.3 GHz Cortex-A7 CPU, Mali-T628 MP6 GPU. Other featrues include a  4.7 inch Super AMOLED display with 720x1280 pixel resolution (~312 ppi pixel density) and TBC protection, Android 4.4 Kitkat with TouchWiz user interface, LTE-A, 12MP rear camera that can support UHD 4K video, 2.1 MP front camera, 2GB RAM, 32GB internal memory but without a MicroSD slot and a 1860mAh battery. Bluetooth v4.0, A2DP, EDR, LE. It has NFC support and microUSB v2.0. Further it is equipped with Accelerometer, Gyro, Proximity, Compass, Heart Rate and Fingerprint Sensor support.

Bypassing OS Password

As discussed on page Cracking OS Password, there are a lot of tools available to accomplish this purpose. But cracking into someone's PC is unethical.








This technique can serve as a remedy for forgotten OS administrator password.

Below  is demonstrated Konboot. This tool is available in both free and commercial version. You can download it here.

Google tests using drones to deliver goods

Google on Thursday said it is testing using drones to deliver items brought online, putting its own spin on similar efforts by internet retail titan Amazon.com.

     Two years of research into what Google referred to as "Project Wing" was capped this month with test flights delivering candy, water, medicine, dog treats and other items to two farmers in Queenland, Australia.

"Self-flying vehicles could open new approaches to moving goods," California-based Google said in a blog post disclosing the project.

"Throughout history, major changes in how to move goods from place to place have led to new opportunities for economic growth and generally made consumers' live easier".

'Project Wing' seems much closer to Google's automated car. This is also a fact that 'Project Wing' and automated car both are developed in same lab 'Google X lab'.

Online business  titan 'Amazon' sought permission for drone test flights in the U.S.A last month saying it is moving forward on plans for deliveries using unmanned aircraft.
