How to Download Official Windows 10 ISO Files from Microsoft

Windows 10 is finally making way to PCs around the globe and Microsoft is offering the free upgrade to everybody running genuine Windows 7 or 8.1. Whilst majority of Windows users will find it easy and convenient to take the upgrade directly and start rocking Windows 10, there is a noticeable percentage of people who like doing a clean install instead of upgrading over and over. Then there are users who have slow data connections, but want to upgrade multiple PCs. This is where a Windows ISO file comes for the rescue. Just get the ISO, burn it to DVD or create a bootable USB and you’re ready to install Windows to as many PCs as needed.
 Downloading Official Windows 10 ISO Files
Windows ISO files are easy to come across and several media sharing websites already have one or multiple copies of Windows 10 available. But the risk is that those files can be infected by the uploaders and malicious software can be installed to the PCs alongside Windows 10. Luckily, Microsoft does offer an easy way to download the official Windows 10 files from its own servers and here’s how to do that.
Note : Even after having the ISO, you’ll need a Windows Product Key to install Windows 10 onto your system.
  • Download the Windows 10 Media Creation Tool from Microsoft website as per your current architecture.
  • Media Creation Tool for 32-bit Windows
  • Media Creation Tool for 64-bit Windows
  • Run it and wait for a couple of minutes for the tool to hit Microsoft website, get the Windows 10 editions and then present the UI.
  • When Windows 10 Setup opens (that’s what Microsoft calls the program’s window), choose Create installation media for another PC and click Next.
  • Choose the Language, Edition and System Architecture for Windows 10 ISO. Then click Next.
  • Choose ISO file, select the location where the ISO should be saved and let the process begin
    Alternatively, you can select USB flash drive at this step and the tool will create a bootable Windows 10 installation usb after downloading the files. Creating an ISO is a better option though.
    When the download finishes, the tool will convert the esd image files it fetched from Microsoft servers to a fully usable ISO image file. You can then put the ISO to whatever use you may want.

How To Make a Pendrive Bootable Using Command Prompt(CMD)



To create a bootable USB drive manually, we will use the Command Prompt as a Windows default program. Here are step by step to create a bootable USB drive as the Windows installation media. To create a bootable USB drive as a Windows installation media, we require at least 4 GB for minimum capacity. Larger capacity is better. At this moment, I use the USB flash drive with 2 GB of capacity as just an example.

  1. Insert your USB flash drive to your running computer. As the first step, we need to run Command Prompt as administrator. To do this, we need to find cmd by typing 'cmd' in the search box on Windows Start Menu. After search result for 'cmd' appears, right click on it and select "Run as administrator".
  2. Type 'diskpart' on Command Prompt (without quotes) and hit Enter. Wait for a while until the DISKPART program run.
  3. Type 'list disk' to view active disks on your computer and hit Enter. There would be seen that the active disks shown as Disk 0 for hard drive and Disk 1 for your USB flashdrive with its total capacity.
  4. Type 'select disk 1' to determine that disk 1 would be processed in the next step then hit Enter.
  5. Type 'clean' and hit Enter to remove all of data in the drive.
  6. Type 'create partition primary' and hit Enter. Creating a primary partition and further recognized by Windows as 'partition 1'.
  7. Type 'select partition 1' an hit Enter. Choosing the 'partition 1' for setting up it as an active partition.
  8. Type 'active' and hit Enter. Activating current partition.
  9. Type 'format fs=ntfs quick' and hit Enter. Formatting current partition as NTFS file system quickly.
  10. Type 'exit' and hit Enter. Leaving DISKPART program but don't close the Command Prompt instead. We would still need it for next process

Hack any WPA2/WEP/WPA Wifi using Dumpper and Jumpstart

Step By Step Guide To Using WinPcap, Dumpper And JumpStart and Get Password:
Download the Dumpper File Here (I realized this version was in Spanish and didn’t have the option to switch languages, so I found an English translated version here.)

WinPcap: Download here

JumpStart: Download here

NOTE: You need to have Microsoft .NET Framework installed on your computer as well, or this will not work. You can install Microsoft .NET Framework here.

Disclaimer: I (The creator of the video has already stated this, but I’d like to go over it again) do not take any responsibility for your actions regarding this tutorial. This was made by the creator to demonstrate weaknesses in wireless networks and for educational purposes only. Breaching other people’s wireless networks without permission is against the law. If you want to test this tutorial, try it on your own home network.

We will be using Dumpper and Jumpstart and other suites to hijack WPA2/WEP/WPA WiFi networks. It’ll let you join without a password, then you can get the password from inside the network. I’ll show you how towards the end of the tutorial. First, download all of the programs above. Now, follow these instructions for setting it up:

Note: Dont STOP the Process. It Takes Several Minutes . Probably 4~5 Hours.(Works Only in Laptops).
Update: We have also Added the Process to Hack Wifi in Desktops Below.


Hack WiFi with Dumpper and Jumpstart:
  1. Download and install JumpStart, WinPcap, and Dumpper
  2. Open Dumpper. It’ll be in Spanish, so go to the far right tab and select ‘English’ in between the other two options.Your programs are set up and ready to go, now begin the process:
  3. In the ‘Networks’ tab, select the network adapter you wish to use. Hit the ‘Scan’ button now.
  4. After it completes the scan, go over to the ‘Wps’ tab. In the area that says ‘Connect using JumpStart’, hit ‘Browse’ to select the location of where you installed JumpStart in the previous set-up steps. (By default, it installs in C:\Program Files (x86)\Jumpstart. Don’t open it, just select the ‘Jumpstart’ folder and click ‘OK’)
  5. In the area ‘Show default pin’, select ‘All networks’ isntead of ‘Only known networks’.
  6. Hit the ‘Scan’ button.
  7. Select the network you wish to penetrate. Remember the ‘Pin’ corresponding to your network in the scan results, this will be needed for later.
  8. In the previous area ‘Connect using Jumpstart’, hit the ‘Start JumpStart’ button.
  9. Under ‘What do you want to do?’, select ‘Join a wireless network’ and hit ‘Next’
  10. Under ‘Which setup method do you want to use?’, select “Enter the PIN from my access point” and enter the PIN next to your network in the scan section back in the previous scan results.
  11. Finally, select the targeted network from before and hit ‘Next’.Now you’re happily connected to that WiFi network you just penetrated. Do you want to see the password so you can get on from other devices without doing this process? Sure! Follow these simple steps:
  12. Open the menu where you join WiFi networks/view the network you’re connected to.
  13. Right click on the network you just joined and hit ‘Properties’
  14. Under the ‘Security’ tab, you can see the password, but it’s just dots. Check the ‘Show characters’ box under it.
  15. The password will then reveal itself.
Done.

Hacking The Wifi on Desktops?
So Many People are Doing this Hack in their Desktops.But unfortunately Desktops are not compatible for using this Hack.But Don’t worry, Here is the trick to do the same Hacking process in Destops even.You just need to buy the Wireless Adapter and Install it in your desktop.

The Top 10 Must Know Keyboard Shortcuts


Using keyboard shortcuts can greatly increase your productivity, reduce repetitive strain, and help keep you focused. For example, to copy text, you can highlight text and press the Ctrl + C shortcut. The shortcut is faster than moving your hands from the keyboard, highlighting with the mouse, choosing copy from the file menu, and then returning to the keyboard.
Below are the top 10 keyboard shortcuts we recommend everyone memorize and use.

Ctrl + C or Ctrl + Insert and Ctrl + X

Both Ctrl + C and Ctrl + Insert will copy the highlighted text or selected item. If you want to cut instead of copy press Ctrl + X.

Ctrl + V or Shift + Insert

Both the Ctrl + V and Shift + Insert will paste the text or object that's in the clipboard.

Use the above text input fields to highlight the "Cut or copy this text" text and press either Ctrl + C to copy or Ctrl + X to Cut the text. Once Cut Move to the next field and press Ctrl + V or Shift + Insert to paste the text.

Ctrl + Z and Ctrl + Y

Pressing Ctrl + Z will Undo any change. For example, if you cut text, pressing this will undo it. These shortcuts can also be pressed multiple times to undo or redo multiple changes. Pressing Ctrl + Y would redo the undo.
Use the above text input field to highlight some or all of the text and then press Ctrl + X to cut the text. Once the text has disappeared press the Ctrl + Z to undo the cut.
Tip: If you did the first example as well (cut and paste text) if you continue to press Ctrl + Z it is also going to undo that change.

Ctrl + F

Pressing Ctrl + F opens the Find in any program. Ctrl + F includes your Internet browser to find text on the current page. Press Ctrl + F now to open the Find in your browser and search for "shortcut" to find each time shortcut is mentioned on this page.

Alt + Tab or Ctrl + Tab

Pressing Alt + Tab switches between open programs moving forward. For example, if you have your browser window open and other programs running in the background press and hold Alt and then press tab to cycle through each open program.
Tip: Press Ctrl + Tab to switch between tabs in a program. For example, if you have multiple tabs open in your browser now press Ctrl + Tab to switch between open tabs.
Tip: Adding the Shift key to Alt + Tab or Ctrl + Tab moves backward. For example, if you are pressing Alt + Tab and pass the program you want to use, press Alt + Shift + Tab to move back to that program.
Tip: Windows Vista and 7 users can also press the Windows Key + Tab to switch through open programs in a full screenshot of the window.

Ctrl + Back space and Ctrl + Left or Right arrow

Pressing Ctrl + Backspace will delete a full word at a time instead of a single character.
Holding down the Ctrl key while pressing the left or right arrow will move the cursor one word at a time instead of one character at a time. If you want to highlight one word at a time, hold down Ctrl + Shift and then press the left or right arrow key to move one word at a time in that direction while highlighting each word.


Ctrl + S

While working on a document or other file in almost every program, pressing Ctrl + S saves that file. Use this shortcut key frequently if you're working on anything important in case an error happens, you lose power, or other problem that causes you to lose any work since the last save.

Ctrl + Home or Ctrl + End

Ctrl + Home will move the cursor to the beginning of the document, and Ctrl + End will move the cursor to the end of a document. These shortcuts work with most documents, as well as web pages.

Ctrl + P

Open a print preview of the current page or document being viewed. For example, press Ctrl + P now to view a print preview of this page.

Page Up, Spacebar, and Page Down

Pressing either the page up or page down key will move that page one page at a time in that direction. When browsing the Internet, pressing the spacebar also moves the page down one page at a time.
Tip: If you are using the spacebar to go down one page at a time, press the Shift key and spacebar to go up one page at a time.

Convert Basic Disk to Dynamic Disk in Windows

This post compares Basic Disk and Dynamic Disk and shows how to convert basic disk to dynamic disk and dynamic disk to basic disk, using Disk Management and CMD / diskpart, without losing the data in Windows 10/8/7.

Basic Disk and Dynamic Disk

There are two types of computer hard disks: Basic disks and Dynamic disks. Basic disks are the commonly used storage media with Windows. They contain partitions like Primary partitions and Logical drives which are typically formatted with a file system. Dynamic disks offer the ability to create fault-tolerant volumes that may even span multiple disks – which Basic disks cannot.
Most home personal computers are configured using Basic disks, however IT professionals usually prefer to use Dynamic disks, as they offer more functionality and increased reliability and performance. While Home editions of Windows support Basic Disks, Enterprise/Pro/Ultimate versions of Windows operating system support Dynamic Disks as well.

Microsoft has listed the operations that can be performed on each of these types.

Operations than can be performed on both, Basic and Dynamic disks:
  1. Check Disk properties, Partition properties and  Volume properties
  2. Establish drive-letter assignments for disk volumes or partitions
  3. Support both MBR and GPT partition styles.
  4. Convert a basic disk to a dynamic disk or a dynamic disk to a basic disk.
Operations that can be performed only on Dynamic disks:
  1. Create and delete simple, spanned, striped, mirrored, and RAID-5 volumes.
  2. Extend a simple or spanned volume.
  3. Remove a mirror from a mirrored volume
  4. Break the mirrored volume into two volumes.
  5. Repair mirrored or RAID-5 volumes.
  6. Reactivate a missing or offline disk. 

Convert a Basic disk to Dynamic disk

Before you start this process, you should know that there could be data loss as a result of this operation, so it is imperative that you first take a backup of your data to an external hard disk. So proceed only if you know what you are doing and be careful.
If you are using a basic disk as a storage area for shadow copies and you intend to convert the disk into a dynamic disk, it is important to take the following precaution to avoid data loss. If the disk is a non-boot volume and is a different volume from where the original files reside, you must first dismount and take offline the volume containing the original files before you convert the disk containing shadow copies to a dynamic disk. You must bring the volume containing the original files back online within 20 minutes, otherwise, you will lose the data stored in the existing shadow copies. If the shadow copies are located on a boot volume, you can convert the disk to dynamic without losing shadow copies, states Microsoft.
Using UI


In Windows 8.1, open the WinX Menu and select Disk Management. Right-click on the Disk and select Convert to Dynamic Disk. You will asked to once again confirm the Disk and click on Convert later on. The process will start and the Disk will be converted to a Dynamic disk.
Using Command line

Open an elevated command prompt, type diskpart and hit Enter.
Next, type list disk. Make note of the disk number of the disk you want to convert to Dynamic.
Now type select diskn and press Enter.
Next type convert dynamic and hit Enter.

Convert Dynamic disk to Basic disk

Using Disk Management
To change a Dynamic disk to a Basic disk, using Disk Management, right-click each volume you want to convert to a basic disk, and select Delete Volume for each volume on the disk. When all volumes on the disk have been deleted, right-click the Disk, and select Convert to Basic Disk. The operation will start.
Using CMD
Open an elevated command prompt and type diskpart and hit Enter.
Next type list disk and note the disk number, of the disk you want to convert to basic. Now type each of these and hit Enter, one after the other:
  1. Type select disk <disknumber>.
  2. Type detail disk <disknumber>.
  3. For each volume on the disk, type select volume= <volumenumber> and then type delete volume.
  4. Type select disk <disknumber>. Specify the disk number of the disk that you want to convert to a basic disk.
Finally, type convert basic and hit Enter. The operation will start.
Remember to always backup first before you carry out any of these operations. And also never convert a Basic disk that contains your operating system to a Dynamic disk, as it could make your system unbootable.
