How to Install the Windows 10 Technical Preview

Microsoft Yesterday announced the newest version of Windows. Today, the company is allowing adventurous users (like yourself) to try it out for free. Here's how.

Before You Install

There are a Some warnings you should be aware of before you do anything:

> Back up your data first: backup on your data before you upgrade if you have anything you can't recover. Or even if you don't. Just do a backup.

> External recovery media to undo the upgrade. As you might expect since you don't have a recovery partition, you'll need a disc or USB drive with Windows 8 (or older) on it to get back to the way things were if you don't like or can't use Windows 10. 

As Microsoft suggest  multiple times, this is pre-release software and is expected to be very buggy and probably crash-prone. It's not advisable that you install this on your work machine or anything you need daily use out of. We'll show you how to install it on a spare PC, or—if you don't have one—in VirtualBox.

What You'll Need:

FIST YOU GO TO THIS ADDRESS : http://windows.microsoft.com/en-us/windows/preview

This time around, Microsoft has created the Windows Insider Program to allow users to test out the new hotness. You'll need to agree to a special terms and condition, In addition to downloading the update, the Insider Program will be how you provide feedback and get help from the community.
Once you're enrolled in the program, here's what you'll need:

One of the Windows 10 ISO files

• A DVD or USB drive to hold a 4GB ISO file
• A spare computer to install it on (Microsoft does not recommend using your daily driver), or VirtualBox installed on your main machine.
• Install the Windows Technical Preview on Your PC

• 
  Once you have everything you need, follow these steps:
  1. Copy the ISO to a disk or USB drive. You can use a tool like ImgBurn to unzip the contents, though if you're installing on a device that's already running Windows, the OS should be able to mount the ISO itself.
  2. Insert the disk or USB drive in the computer that you want to install Windows 10 on.
  3. If you have an older copy of Windows installed on that machine, start it up and double-click setup.exe from the installation media. If not, you can boot up your PC from the installation disc to start installation.
  4. Follow the wizard to install Windows on your machine.
  Microsoft's wizard will walk you through the rest of the installation process. If you want to do a clean install, make sure you choose to "Keep Nothing" during the wizard.

  Option Two: Install the Windows Technical Preview in VirtualBox

  
  If you don't have a spare machine to try out the Technical Preview, we recommend installing it in VirtualBox. That way, you can try it out, see what's new, and play around without overwriting your main system.
  1. Download and install the latest version of VirtualBox, and star t it up.
  2. Click the "New" button in the main window to create a new virtual machine.
  3. Give your operating system a name (like "Windows 10 Technical Preview") and choose Windows 8.1 from the list (since VirtualBox doesn't have a Windows 10 option yet).
  4. Follow the VirtualBox wizard to set up your virtual machine. 
  5. When it finishes, you should see your new machine in the left-hand sidebar. Click on it and hit the Settings button along the top of the VirtualBox window.
  6. Head to Storage in the left sidebar, and next to "Controller: IDE", click the Add CD button.
  7. Select "Choose Disk" and navigate to your downloaded Windows 10 ISO.
  8. Click OK.
  9. Press Start to start up your new virtual machine and go through the Windows 10 installation process.
  Warning: Before install windows 10 Remember this is pre-release software, so install at your own risk! If you aren't interested in risking your machine, we'll be poring over the new OS to let you know what other cool stuff Windows 10 has in store over the next couple days. Enjoy !!

WHAT FEATURE COME LET'S SEE

                                                                             Article writer : Roshan Ekka   

1. start-menu-on-screen

Microsoft again with starting the Start menu. Windows 10 revives the old standby, but rather than focusing on desktop programs alone, the Windows 10 Start menu fuses a traditional Start menu layout with a mini-Start screen of sorts, populated with tiles for the Windows Apps or desktop programs of your choosing.

2. The squat Start menu

You can also resize the Start menu as you see fit, shrinking it down ‘til it’s squat or dragging it almost all the way up to the top of the screen. It’ll automatically expand horizontally as you add more and more Live Tiles to the Start menu.

3. Pick your poison

Windows 10 for PCs defaults to the desktop and the new Start menu, but you can bring the Windows 8 Start screen back if you'd like. Right-click on the taskbar, selectProperties, open the Start Menu tab, and uncheck the box next to “Use the Start menu instead of the Start screen.”

After you click OK you’ll be prompted to sign out of Windows, and then log back in…

4.Windows 10 Start screen

where you’ll promptly be greeted by the full-screen Start screen! Yep, it’s still here—just hidden.

5.Start menu customization options

The same Start menu tab that allows you to default to the Start screen also includes a Customize button that lets you tweak exactly how the desktop Start menu behaves, as well as which specific shortcuts appear on it.

6. Metro apps meet the desktop

As promised, Windows Apps now appear in desktop windows, rather than being the full-screen-only giants they were in Windows 8. They can be resized just like any other desktop window. Meanwhile, the mouse-friendly Windows App menu bar introduced in Windows 8.1’s spring update has blossomed: It’s now full of options that used to be buried behind the Charms bar.

7. Snap suggestions

Those Windows Apps can be split-screen Snapped next to traditional programs on the desktop in Windows 10. Another nifty feature: After you Snap a window to half (or whatever) of the screen, the operating system pops up suggestions of running apps you may want to Snap next to it in the “open” half of the screen. It’s reminiscent of the tiling windows management found in Linux PCs.

8. Search on the desktop

Now for the two new icons next to the Start button: First up is the magnifying glass icon, which brings up Windows 10’s search feature. The feature largely mimics the search functionality baked into the Windows 8 Start screen, surfacing programs, files, and even Bing-surfaced web pages related to your search queries. It’s lightning-quick and insanely useful—just like Windows 8’s search capabilities.
