# Windows 8.1 ISO File Download 64\-bit & 32\-bit \[Free & Safe\]

## How to download Windows 8.1?

**Quick Answer:**

Microsoft no longer offers the download options for Windows 8.1 ISO. You can download it with the archive sources.

If you download Windows 8.1 for tests, no need to waste time creating a bootable USB installer.

Use iBoysoft DiskGeeker for Windows to clone the OS partition of a Windows 8.1 computer. Then, you can use this Windows 8.1 bootable copy to directly start up compatible computers, no configuration steps needed.

Microsoft stopped offering technical assistance and software updates for Windows 8.1 on January 10, 2023. After that time, it also removed the official download options for the Windows 8.1 ISO file.

Since Microsoft no longer provides a direct download page for Windows 8.1, finding a safe ISO has become confusing and risky.

In this guide, I've verified which sources still host original, unmodified Windows 8.1 ISO files, and I'll show you:

- How to check if the ISO file is genuine
- How to create a Windows 8.1 bootable USB installer and install Windows 8.1

Important Tips: Since Microsoft ended support for Windows 8.1, use Windows 8.1 only for testing, virtual machines, and legacy software compatibility.

## How I verified these ISO files \(For security, it's important\)

Before using these downloads, I checked:

✔ File source \(archive.org integrity\) ✔ File size consistency with official releases ✔ Verify the integrity of the downloaded ISO

Here's how I check the integrity of the Windows 8.1 ISO:

1. Open Command Prompt as an administrator.
2. Run the command below: certutil \-hashfile "FULL\_PATH\_TO\_ISO" SHA1 Replace FULL\_PATH\_TO\_ISO with the real path of the downloaded ISO file. For example: certutil \-hashfile "C:\\Users\\ConnieYang\\Downloads\\Win8.1.iso" SHA1
3. Read the output and compare it with the one that is along with the archive source. If they match, the ISO is authentic and unmodified.

👉 If you want to be extra safe, you can:

- Compare SHA256 checksum values
- Scan the ISO with antivirus tools
- Test inside a virtual machine first \(Check the installation behavior and see if any modification prompts or anomalies\)

## How to create a Windows 8.1 bootable USB

As an older version of Windows, Windows 8.1 is often downloaded for tests.

If you are going to create a Windows 8.1 bootable USB to start up different computers for some tests, it's not necessary, as this process is troublesome.

You can use[iBoysoft DiskGeeker for Windows](https://www.m3datarecovery.com/diskgeeker/)to clone the OS partition \(C: drive\) of a Windows 8.1 PC. Then, you'll get a bootable copy of Windows 8.1 and directly use it to start up multiple compatible PCs without any setup.

1. Connect a clean USB drive or external hard drive to a Windows 8.1 computer. Ensure the capacity of this drive is larger than that of the OS partition of this PC. Or else, the cloning process won't succeed.
2. Download, install, and open iBoysoft DiskGeeker for Windows on the Windows 8.1 computer.
3. The software will automatically list the Windows 8.1 system partition in the Source OS disk section. ![clone Windows 8 1 OS partition](https://iboysoft.com/images/windows/windows-8-1-iso-download/windows-8-1-partition-clone.jpg)
4. Click "Select a destination disk" and choose your target USB drive or external disk. ![select a destination for Windows 8 1 OS partition](https://iboysoft.com/images/windows/windows-8-1-iso-download/select-destionation-for-windows-8-1-partition.jpg)
5. Click "Start" and confirm the prompt to start cloning the OS partition on the Windows 8.1 PC.

After the cloning process completes, you can connect this bootable copy of Windows 8.1 to compatible computers for tests. Also, you can use it to boot up a computer that won't start up.

### Use Rufus to create a Windows 8.1 bootable USB

If you create a Windows 8.1 bootable USB for system recovery or reinstallation, you can use Rufus to finish this task.

1. Download Rufus from its [official website](https://rufus.ie/en/) .
2. Connect a USB with at least 16 GB \(for 32\-bit Windows 8.1\) or 20 GB \(for 64\-bit Windows 8.1\) storage space.
3. Open Rufus and choose your USB drive.
4. In the Boot selection field, choose your downloaded Windows 8.1 ISO file.
5. Finish configuration for the USB drive. ![create a Windows 8 1 bootable USB with Rufus](https://iboysoft.com/images/windows/windows-8-1-iso-download/windows-8-1-bootable-usb-with-rufus.jpg)
6. Click "START."
7. Follow the on\-screen instructions to finish creating a Windows 8.1 bootable USB.

## How to install Windows 8.1 on a PC

During installation, Windows 8.1 will force you to enter a product key — you can't skip this step like in Windows 10 or 11.

What many people don't know is that Microsoft provides generic installation keys. These keys:

- Allow you to complete the installation
- But do NOT activate Windows 8.1

Here is the list of Windows 8.1 generic installation keys offered by Microsoft:

| **Edition** | **Generic Installation Key \(offered by Microsoft\)** |
| --- | --- |
| Windows 8.1 \(Core\) | 334NH\-RXG76\-64THK\-C7CKG\-D3VPT |
| Windows 8.1 Pro; Windows 8.1 Pro Pack | XHQ8N\-C3MCJ\-RQXB6\-WCHYG\-C9WKB |
| Windows 8.1 Enterprise | MHF9N\-XY6XB\-WVXMC\-BTDCT\-MKKG7 |
| Windows 8.1 Professional with Media Center | GBFNG\-2X3TC\-8R27F\-RMKYB\-JK7QT |

⚠️ Notably,**avoid downloading "free product keys" from unknown sources**and**do NOT use cracked versions**\(illegal and unsafe\).

I tested this during setup on a virtual machine, and it works reliably for installing the system.

The edition installed \(Core, Pro, Enterprise, Pro Pack, etc.\) is determined by the key you enter.

### Steps to install Windows 8.1 on a PC with a bootable USB installer:

1. Power off the PC.
2. Insert your Windows 8.1 USB installer into the PC.
3. Power on the PC and immediately press the Boot Menu key repeatedly. Dell: F12 HP: Esc / F9 Lenovo: F12 / Fn \+ F12 ASUS: Esc / F8 Acer: F12 If unsure, quickly tap F12 or Esc—those work on most systems.
4. In the Boot Menu, select your USB drive, select it, and press Enter.
5. Finish setup. Note: If you use iBoysoft DiskGeeker for Windows to clone a bootable copy of a Windows 8.1 OS partition, there's no need to perform a setup.
6. Follow the on\-screen guide to finish installation.
