Windows 10 ISO Download [Guide]
Need to download a Windows 10 ISO file to reinstall Windows, create a bootable USB drive, or set up a virtual machine? You’re in the right place. A Windows 10 ISO file contains the installation files required to install or reinstall the operating system on a compatible computer.
Microsoft provides an official Windows 10 download page where you can download the Media Creation Tool or obtain an ISO image, depending on your device and browser. Using the official source helps you avoid modified installation files and potentially unsafe third-party downloads.
Before getting started, there’s one important thing to know. Windows 10 reached the end of standard support on October 14, 2025.
Microsoft no longer provides regular free security updates or technical support for standard Windows 10 Home and Pro installations.
You can still download and install Windows 10, but consider Windows 11 or the applicable Extended Security Updates program if you need continued protection.
In this guide, you’ll learn how to download the Windows 10 ISO, choose the correct architecture, create a bootable USB drive, and use the ISO to install Windows.
Windows 10 ISO Download [Guide]
A Windows 10 ISO file is a disc image containing Windows installation files. You can save it on your computer, mount it to access its contents, use it to create installation media, or load it into a virtual machine.
The safest place to start is Microsoft’s official download page:
Official download page: https://www.microsoft.com/en-us/software-download/windows10
You can use the Media Creation Tool to create an ISO file or download an ISO directly when the website offers that option.
The available download method can vary depending on your operating system and browser.
1: Check Your Computer Before Downloading
Before downloading Windows 10, check your computer’s system type and make sure you have enough storage space. This helps you choose the correct installation files and avoid problems later.
Press Windows + I to open Settings. Select System, then scroll down and click About. Under Device specifications, find System type.
You’ll typically see a description indicating whether your processor and operating system are 64-bit or 32-bit. Most modern computers use 64-bit Windows, but older systems may require a different installation option.
Next, check your available storage space. Open File Explorer, select This PC, and look at the free space on your Windows drive. Make sure you have enough room for the ISO download and any additional installation files.
If you’re planning to create a bootable USB drive, prepare a separate USB flash drive with at least 8 GB of storage. Back up anything stored on it because creating installation media will erase its contents.
2: Open the Official Windows 10 Download Page
Launch your web browser and visit Microsoft’s official Windows 10 download page:
https://www.microsoft.com/en-us/software-download/windows10
Make sure the website address belongs to microsoft.com before downloading anything. Avoid unofficial websites that offer modified Windows ISO files, preactivated copies, or suspicious download managers.
On the page, look for the section titled Create Windows 10 installation media. Microsoft provides a Media Creation Tool that can help you download Windows installation files and create installation media.
Select Download Now to download the tool if that option is available.
If Microsoft directs your browser to a page for downloading the ISO directly, you can use the available edition, language, and architecture options instead.
Both methods can help you obtain Windows installation media, but the exact screens may differ.
3: Download and Run the Media Creation Tool
Once the download finishes, open your browser’s Downloads folder and locate the Media Creation Tool executable. Its filename may look similar to MediaCreationTool_22H2.exe.
Double-click the file to launch it. If Windows displays a User Account Control prompt asking whether you want to allow the app to make changes, verify that you downloaded the tool from Microsoft and select Yes.
Wait while the tool prepares the setup files. When the license terms appear, read them and select Accept if you agree.
The tool may take a little time to load, especially on a slower computer. Keep your internet connection active and avoid closing the program while it prepares the installation process.
If the tool won’t launch, check whether your current Windows version and browser support the download method you’re using.
You can also return to Microsoft’s official download page and check whether direct ISO downloads are available.
4: Choose the ISO Download Option
After the Media Creation Tool opens, you’ll see a screen asking what you want to do.
Select Create installation media (USB flash drive, DVD, or ISO file) for another PC, then click Next.
The next screen lets you choose the language, edition, and architecture. If the option to use the recommended settings for your PC is selected, Windows may automatically fill in these details.
Uncheck that option if you need to select different settings for another computer. Choose the language you want to install and the appropriate architecture for your target device.
Click Next to continue.
When the tool asks which media you want to use, select ISO file and click Next. This tells the tool to save the Windows installation image on your computer instead of immediately creating a USB drive.
5: Select a Location and Download the Windows 10 ISO
The Media Creation Tool will ask where you want to save the ISO file. Choose a location with sufficient free storage, such as your Downloads folder or another drive with enough space.
Enter a recognizable filename if the tool allows you to change it, then click Save.
The tool will begin downloading Windows 10 and creating the ISO image. Depending on your internet speed and computer performance, the process may take several minutes or longer.
Don’t disconnect your internet connection or shut down your computer while the download is running. When the process finishes, the tool should confirm that the ISO file is ready.
Click Finish to close the tool. Open the folder you selected and verify that the ISO file is present.
Important: The Media Creation Tool generally downloads the Windows 10 release offered through Microsoft’s current installation media workflow. It isn’t a general archive for every historical Windows 10 version.
Download the ISO Directly From Microsoft
If you don’t want to use the Media Creation Tool, check whether Microsoft offers direct ISO downloads through its website.
Open the official Windows 10 ISO download page:
https://www.microsoft.com/en-us/software-download/windows10ISO
If the page offers an edition selection, choose the available Windows 10 option and confirm it. Select your preferred language if prompted, then choose the appropriate download link for your system architecture.
A 64-bit download is generally appropriate for modern computers with 64-bit processors. Choose 32-bit only when you specifically need it and the target hardware supports it.
Download links may expire after a limited period, so use them promptly.
The available choices can change, and Microsoft may direct Windows users to the Media Creation Tool instead.
Create a Bootable Windows 10 USB Drive
Once you have the ISO, you can use it to create a bootable USB drive for installing Windows on a compatible computer.
Connect a USB flash drive with at least 8 GB of storage. Back up its contents first because the creation process will erase the drive.
You can use Microsoft’s supported media creation workflow or a reputable USB creation utility that supports Windows ISO files. If you use the Media Creation Tool, select the USB flash drive option instead of ISO and follow the instructions.
If you already have the ISO, open your chosen USB creation utility, select the ISO file, and choose the correct USB drive. Follow the tool’s instructions to create the bootable media.
Be careful when selecting the target drive. Choosing the wrong drive can erase important data.
When the process finishes, safely eject the USB drive. You can then use it to start a compatible computer and begin Windows Setup.
Install Windows 10 Using the ISO File
You don’t always need a USB drive to use a Windows ISO. If you’re already running Windows, you can mount the ISO and start Setup directly.
Locate the ISO file in File Explorer, right-click it, and select Mount. Windows will make the ISO contents available as a virtual DVD drive.
Open the new drive and double-click setup.exe. Follow the on-screen instructions to begin the installation.
If you want to reinstall Windows while keeping your files and apps, review the available options carefully before proceeding. The options depend on your current Windows installation and the media you’re using.
For a clean installation, you generally need to boot from installation media and follow the Windows Setup process. A clean installation can remove existing files, applications, and settings, so back up your important data first.
You may also need a valid Windows license or digital entitlement for activation. Installing Windows does not automatically guarantee that every edition will activate on every computer.
Verify the ISO and Prepare for Installation
Before using the ISO, check that the download completed successfully and that the file is accessible. If the download was interrupted or the file appears unusually small, download it again from Microsoft.
If you need stronger verification, compare the ISO’s cryptographic hash against a trustworthy hash published by Microsoft for that exact file, if Microsoft provides one. You can calculate a local SHA-256 hash using PowerShell, but a hash is useful for authenticity only when you have a reliable reference value for comparison.
Before installing Windows, back up your documents, photos, and other important files. Make sure you have the drivers needed for your computer, particularly network drivers if your hardware requires them to connect to the internet.
Finally, remember that Windows 10’s standard support ended in October 2025.
If you’re installing it on a computer that connects to the internet, review your options for Windows 11 or Extended Security Updates before deciding to continue.
FAQs
1. Is the Windows 10 ISO download free?
Yes. Microsoft provides Windows 10 installation media for download at no charge. However, activation may require a valid product key or an eligible digital license.
2. Which Windows 10 ISO should I download, 32-bit or 64-bit?
Most modern computers use 64-bit Windows. Check your processor and system type before downloading. If you’re installing Windows on another computer, choose the architecture that its hardware supports.
3. Can I install Windows 10 without a USB drive?
Yes. If you’re already running Windows, you can mount the ISO and run setup.exe to start an installation or supported upgrade process. For a clean installation on a computer that can’t boot into Windows, bootable installation media is usually the better option.
4. Can I use the same Windows 10 ISO on multiple computers?
You can use installation media on multiple compatible computers, but each installation must comply with Microsoft’s licensing requirements. A license for one computer doesn’t automatically grant activation rights on every other computer.
5. Is Windows 10 still supported?
Standard Windows 10 support ended on October 14, 2025. Eligible consumer devices enrolled in Microsoft’s Extended Security Updates program can receive security updates for a limited additional period, currently through October 12, 2026, with the program’s availability and enrollment requirements applying. Check Microsoft’s current guidance before relying on continued updates.
