You can download the official 90-day evaluation ISO for Windows 11 IoT Enterprise LTSC 2024 from Microsoft.
The LTSC edition does not include the Media Creation Tool, and you must use third-party tools such as Rufus or Ventoy to create a bootable USB drive.
A non-evaluation ISO is also available via Archive.org (community-hosted source).

Although Microsoft reserves Windows 11 Long-Term Servicing Channel (LTSC) editions for organizations, it’s possible to download the ISO file to install the operating system on virtually any hardware.

Create Windows 11 LTSC bootable USB

Long-Term Servicing Channel releases do not include the Media Creation Tool, so you’ll need a third-party tool, such as Rufus, to create a bootable USB drive. Alternatively, you can use Command Prompt or third-party solutions such as Ventoy.

To create a bootable USB with Rufus using an existing ISO file, connect a USB flash drive with 8GB of space and use these steps:

Open the Rufus website.
Click the link to download the latest version under the “Download” section.
Double-click the rufus.4.xx.exe file to launch the tool.
Select the USB flash drive to create the Windows 11 LTSC bootable media under the “Device” section.
Click the Select button.
Select the Windows 11 IoT Enterprise LTSC 2024 ISO file.
Click the Open button.
Choose the “Standard Windows 11 Installation” option under the “Image option” setting.
Select the GPT option under the “Partition scheme” section.
Select the UEFI (non-CSM) option under the “Target system” section.
Specify a descriptive name for the bootable USB drive under the “Volume label” section. For example, Windows 11 LTSC Setup.
Use the default settings for the File system and Cluster size options.
Check the Quick format option.
Check the “Create extended label and icon files” option.
Clear the customization options (as necessary).
Click the Start button.
Click the OK button to confirm the USB’s deletion and the bootable drive’s creation.

After you complete the steps, the tool will begin creating a USB media with the Windows 11 LTSC installation media.

FAQs about downloading the Windows 11 LTSC ISO file

To help you better understand Long-Term Servicing Channel (LTSC) editions, I’ve answered some of the most common questions:

What is Windows 11 LTSC, and who is it for?

Windows 11 LTSC is the Long-Term Servicing Channel edition designed for stability and minimal feature changes. It targets organizations that need consistent performance over the years, such as healthcare or industrial systems. It excludes frequent feature updates and consumer apps found in standard releases.

What is the difference between Windows 11 LTSC and regular Windows 11?

Windows 11 LTSC focuses on long-term stability and receives only security and quality updates, while regular Windows 11 gets frequent feature updates and app changes. LTSC also removes many preinstalled consumer apps, making it leaner and more predictable for enterprise environments.

Windows 11 LTSC vs Windows 11 Pro: which should I install?

Windows 11 LTSC is best for long-term stability and minimal changes, while Windows 11 Pro is better for everyday users who want ongoing feature updates. LTSC avoids major feature upgrades, whereas Pro evolves continuously with new tools, AI features, and interface improvements.

Is Windows 11 IoT Enterprise LTSC the same as Enterprise LTSC?

Windows 11 IoT Enterprise LTSC is functionally similar to Enterprise LTSC but licensed primarily for specialized and embedded devices. Both offer long-term servicing and reduced feature changes. However, licensing terms and intended deployment scenarios differ significantly.

How do I download the official Windows 11 LTSC ISO?

You can download the official 90-day evaluation ISO from Microsoft’s Windows 11 IoT Enterprise LTSC download page. Select the x64 edition and save the ISO file. The file can then be mounted for a virtual machine or used to create bootable installation media.

Why doesn’t Windows 11 LTSC have the Media Creation Tool?

Windows 11 LTSC does not include the Media Creation Tool because it is intended for controlled enterprise deployments. Microsoft expects organizations to use volume licensing portals or deployment tools. Home users must rely on third-party tools to create bootable media.

How do I create a Windows 11 LTSC bootable USB drive?

To create a Windows 11 LTSC bootable USB drive, use a third-party tool such as Rufus. Select the downloaded LTSC ISO, choose GPT and UEFI for modern systems, and start the process. An 8GB USB drive is typically required for successful installation media creation.

Can I activate Windows 11 LTSC after the 90-day evaluation ends?

Yes, but only with a valid volume license key. The 90-day evaluation edition cannot be permanently activated without proper licensing. After the trial expires, the system will require activation, and you must enter a genuine Enterprise LTSC product key obtained through Microsoft Volume Licensing.

Does Windows 11 LTSC receive feature updates?

No, Windows 11 LTSC does not receive annual feature updates like standard Windows 11 editions. Instead, it only receives security and quality updates for its lifecycle. New features are introduced only with a new LTSC release, typically every few years.

Can I upgrade from Windows 11 Pro to Windows 11 LTSC?

No, there is no direct in-place upgrade path from Windows 11 Pro to LTSC. You must perform a clean installation using the LTSC ISO. This process removes existing apps and settings, so backing up your data before installation is essential.
