How to install and activate Windows 8 with en_windows_8_x64_dvd_915440.iso

If you have a product key for Windows 8, but you don't have the installation media, you might be wondering how to get a legitimate copy of the ISO image file. In this article, we will show you how to download, install and activate Windows 8 using the en_windows_8_x64_dvd_915440.iso file, which is the English version of Windows 8 for 64-bit systems.

Step 1: Download the ISO image file

The en_windows_8_x64_dvd_915440.iso file is available on various websites and torrent sites, but not all of them are trustworthy. To avoid downloading a corrupted or infected file, you should verify the SHA1 hash of the file before opening it. The SHA1 hash is a unique identifier that can be used to check the integrity and authenticity of a file.


The official SHA1 hash of the en_windows_8_x64_dvd_915440.iso file is:


You can find this information on the MSDN Subscriber Downloads page, where Microsoft publishes the file names and hashes of all its products. You can also use a search engine to find other sources that provide the same hash.

Once you have found a reliable source, you can download the ISO image file using your preferred method. Make sure you have enough disk space and a stable internet connection. The file size is about 3.3 GB.

Step 2: Burn the ISO image file to a DVD or USB drive

After downloading the ISO image file, you need to burn it to a DVD or USB drive that you can use to boot your computer and install Windows 8. You can use any software that can create bootable media from ISO files, such as Rufus, ImgBurn, or Windows USB/DVD Download Tool. Follow the instructions of the software to select the ISO image file, the destination drive, and the appropriate settings.

If you are using a DVD, make sure you have a blank DVD-R or DVD+R disc with at least 4.7 GB of capacity. If you are using a USB drive, make sure it has at least 4 GB of free space and that it is formatted as FAT32 or NTFS. Note that all data on the USB drive will be erased during the process.

Step 3: Install Windows 8 from the bootable media

Once you have created the bootable media, you can use it to install Windows 8 on your computer. To do this, you need to change the boot order in your BIOS or UEFI settings to make your computer boot from the DVD or USB drive instead of your hard drive. The exact steps may vary depending on your computer model and manufacturer, but usually you need to press a key such as F2, F10, F12, or Esc during startup to access the BIOS or UEFI menu.

After changing the boot order, save and exit the BIOS or UEFI menu and restart your computer. You should see a message asking you to press any key to boot from the DVD or USB drive. Press any key and wait for the Windows 8 setup to load.

Follow the on-screen instructions to select your language, keyboard layout, and time zone. When prompted, enter your product key for Windows 8. You can find your product key on a sticker attached to your computer case or on a card that came with your purchase. If you have lost your product key, you can try to recover it using a tool such as ProduKey or Belarc Advisor. However, these tools may not work if your computer came with Windows 8 preinstalled and activated via BIOS.

After entering your product key, accept the license terms and choose whether to upgrade your existing Windows installation or perform a custom installation. If you choose to upgrade, your files and settings will be preserved. If you choose to perform a custom installation, you will need to select a partition where to install Windows 8 and format it if necessary. Note that this will erase all data on the partition, so make sure you have backed up your important files before proceeding.

Wait for the installation to complete. Your computer may restart several times during the process. Do not turn off your computer or remove the bootable media until the installation is finished.

Step 4: Activate Windows 8

After installing Windows 8, you need to activate it to verify that your product key is valid and that you are using a genuine copy of Windows. Activation is usually done automatically over the internet, but you can also do it manually by phone if you have problems with the online activation.

To check your activation status, go to Settings > PC info and look for the Windows activation section. If your Windows is activated, you will see a message saying "Windows is activated". If your Windows is not activated, you will see a message saying "Windows is not activated" and a link to activate Windows now.

If you click on the link, you will be taken to the activation wizard, where you can choose how to activate Windows. If you have an internet connection, select "Activate Windows online now" and follow the instructions. If you don't have an internet connection or if the online activation fails, select "Show me other ways to activate" and choose "Use the automated phone system". You will be given a toll-free number to call and a set of numbers to enter on your phone keypad. Follow the voice prompts and enter the confirmation ID that you receive on your screen.

After activating Windows 8, you can enjoy all the features and benefits of your new operating system. You can also customize your settings, install updates, and download apps from the Windows Store.
