Need to download a Windows 10 ISO file in 2026? Whether you’re reinstalling Windows, creating a bootable USB drive, setting up a virtual machine, or repairing an older PC, an ISO file can help you get the installation files you need in one convenient package.
A Windows 10 ISO file is a disc image that contains the files required to install the operating system. You can save it on your computer, mount it to access its contents, or use it to create bootable installation media. The process is useful for both beginners and experienced PC users.
However, there’s one important detail to understand in 2026. Windows 10 reached the end of standard support on October 14, 2025. This means most users no longer receive regular security updates or technical support through the standard support program. Eligible devices may receive Extended Security Updates (ESU), but downloading an ISO file does not automatically enroll your PC in that program.
For security reasons, always get Windows installation files from Microsoft or another source you can verify. Avoid unofficial download sites that bundle modified installers or potentially harmful software.
In this guide, you’ll learn how to find the official Windows 10 ISO download, choose the right edition and architecture, create a bootable USB drive, and install Windows safely.
Let’s get started!
Windows 10 ISO File Download in 2026 [Complete Guide]
To download a Windows 10 ISO file in 2026, follow these steps:
- Visit Microsoft’s official Windows 10 download page.
- Check whether Microsoft offers a direct ISO download or the Media Creation Tool for your device and browser.
- If available, download the Windows 10 ISO file or use the official tool to create installation media.
- Select the appropriate language and architecture, such as 64-bit (x64), based on your PC’s requirements.
- Save the ISO file to a drive with enough free storage space.
- If you need to install Windows, use the ISO to create a bootable USB drive with a suitable tool.
- Back up your files, verify your Windows license, and check your PC’s compatibility before reinstalling the operating system.
Important: Windows 10 is no longer in standard support. Check Microsoft’s current download options and security support information before proceeding.
Step 1: Open Microsoft’s Official Windows 10 Download Page
The safest way to download Windows 10 installation files is through Microsoft’s official website. Open your preferred browser and search for the Windows 10 software download page. Make sure the page belongs to Microsoft before downloading anything.
You can use the official Windows 10 download page. Depending on your browser, location, and Microsoft’s current download options, you may see the Media Creation Tool rather than a direct ISO download button.
The navigation path is Browser > Microsoft Windows 10 Download Page > Create Windows 10 Installation Media.
If the Media Creation Tool is available, select Download Now to download the official utility. This tool can download Windows 10 files and create installation media, including a USB drive or an ISO file.
Avoid third-party websites offering modified ISO files, activation bypasses, or supposedly preactivated Windows installations. These downloads can contain unwanted software or compromise your computer’s security.
Step 2: Download the Windows 10 ISO File
Once you have opened Microsoft’s download page, check which download options are available. On supported devices and browsers, Microsoft may provide direct ISO download options. In other cases, the page may direct you to the Media Creation Tool.
If you have downloaded the tool, locate the file in your Downloads folder and double-click it. Approve the User Account Control prompt if it appears. You may need an administrator account to run the utility.
Read the license terms and select Accept if you agree. When asked what you want to do, select Create installation media (USB flash drive, DVD, or ISO file) for another PC, then select Next.
The navigation path is Downloads > Media Creation Tool > Accept > Create installation media for another PC.
If the tool offers a choice between a USB flash drive and an ISO file, select ISO file. Choose a folder where you want to save the download, enter a recognizable filename if prompted, and allow the tool to finish downloading the installation files.
Keep your computer connected to the internet throughout the process. Download times depend on your connection speed and Microsoft’s server availability.
Step 3: Select the Correct Language, Edition, and Architecture
Before creating installation media, make sure you select settings that match the computer where you intend to install Windows.
The Media Creation Tool may automatically select recommended settings based on the PC you are using. If you need installation media for another computer, you can clear the option to use the recommended settings for this PC and choose the appropriate language and architecture.
For most modern computers, 64-bit (x64) is the appropriate architecture. However, older computers may require 32-bit (x86) Windows, so check the target computer’s specifications before proceeding.
The navigation path is Media Creation Tool > Language > Edition > Architecture > Next.
Windows 10 Home and Pro installation files are generally included in the standard consumer media, with the installed edition determined by the applicable license and installation choices. Enterprise editions follow separate licensing and distribution arrangements.
Choose the language you actually need. If your existing license is for Windows 10 Home, installing Pro will not automatically give you a valid Pro license.
Step 4: Save and Verify the Downloaded ISO File
After selecting the ISO file, choose a convenient location on your computer. Your Downloads folder or a dedicated folder on another drive can work well.
Make sure the destination drive has enough free storage space. The ISO file can occupy several gigabytes, so avoid saving it to a nearly full drive.
Once the download finishes, open File Explorer and navigate to the folder where you saved it. You should see a file with the .iso extension.
The navigation path is File Explorer > Downloads or Selected Folder > Windows 10 ISO File.
If you want to check the file’s integrity, compare its SHA-256 hash with a value published by a trusted, authoritative source for that exact ISO. You can calculate a hash in Windows PowerShell using the command Get-FileHash “C:\Path\Windows10.iso” -Algorithm SHA256, replacing the example path with your actual file path.
A matching hash helps confirm that the file matches the reference copy. If you cannot find an authoritative reference hash, do not assume that a calculated hash alone proves the ISO is genuine.
Step 5: Create a Bootable USB Drive
If you plan to install Windows 10 on a physical computer, you can use your ISO file to create a bootable USB drive.
You will need a USB flash drive with at least 8 GB of storage. Back up any files on it first because the media creation process can erase its contents.
If you still have access to the Media Creation Tool, you can use it directly to create a bootable USB drive instead of saving an ISO first. Alternatively, a reputable utility such as Rufus can create installation media from an existing ISO file.
The navigation path is ISO File > USB Creation Utility > Select USB Drive > Start.
Check that you have selected the correct USB drive before proceeding. Selecting the wrong drive could erase important files. If you use a third-party utility, follow its instructions and use the settings appropriate for your computer’s firmware, such as UEFI or legacy BIOS.
Once the process finishes, safely eject the USB drive. It is now ready for use on a compatible computer.
Step 6: Install Windows 10 Using the ISO or USB Drive
Before reinstalling Windows, back up your documents, photos, passwords, and other important data. Make sure you have access to your license information and any necessary device drivers.
If you only want to access the ISO’s files from a working Windows computer, right-click the ISO file and select Mount. Windows will display its contents as a virtual drive. You can use the installation files to begin an upgrade, provided the existing system and installation method support it.
For a clean installation, restart your computer and open its boot menu. Select the bootable USB drive, then follow the Windows Setup instructions.
The navigation path is Restart PC > Boot Menu > USB Drive > Windows Setup > Install Now.
Be careful when selecting a drive or partition during setup. Formatting or deleting partitions can permanently erase data. If you are reinstalling Windows on a computer with multiple drives, identify the correct destination before making changes.
You may be asked for a product key. If your device has a valid digital license for the edition being installed, you may be able to select the option to skip entering a key and activate Windows after installation.
Step 7: Check Activation and Security After Installation
After installing Windows 10, connect to the internet and check your activation status. Open Settings > Update & Security > Activation to review whether Windows is activated.
A valid license is still required. Downloading an ISO does not provide a license or guarantee activation.
You should also consider the operating system’s support status. Windows 10 reached the end of standard support on October 14, 2025. Eligible personal devices running Windows 10 version 22H2 can enroll in Microsoft’s Extended Security Updates (ESU) program, which provides eligible critical and important security updates through October 12, 2027. ESU does not include regular feature improvements or general technical support.
The navigation path for checking ESU availability is Settings > Update & Security > Windows Update. If your device is eligible, follow the enrollment instructions displayed there.
If your computer supports Windows 11, consider upgrading to remain on a Windows version with ongoing standard support.
