To download the Windows 11 24H2 IoT Enterprise LTSC evaluation ISO, head to the Microsoft Evaluation Center page for Windows 11 IoT Enterprise LTSC, fill out the short registration form, and pick the 64-bit ISO. The file is around 4 GB and gives you a fully functional 90-day evaluation of the LTSC build (26100) — no product key required up front.
Applies to: Windows 11 IoT Enterprise LTSC 2024 (24H2, build 26100) | Last updated: May 15, 2026
Key Takeaways
- The download is free and legitimate — the ISO comes straight from Microsoft’s Evaluation Center, the same place IT pros use to test enterprise builds.
- You get a 90-day evaluation with no product key needed at install — Windows activates as an evaluation copy automatically.
- The product on the page is “Windows 11 IoT Enterprise LTSC” (build 26100, the 24H2 servicing branch). This is the only consumer-accessible LTSC ISO for 24H2.
- LTSC strips out the Microsoft Store, Edge, Cortana, and most modern apps. It receives security updates only for 10 years — no feature drops, no AI features, no version churn.
- If you just want a clean, debloated regular Windows 11, you do not need LTSC — my own tool, Winhance, gets you most of the same benefits on Home or Pro.
Quick Steps
- Open the Microsoft Evaluation Center page for Windows 11 IoT Enterprise LTSC.

- Click Download Now, then pick 64-bit edition (for standard PCs) or ARM64 edition (for Snapdragon X / ARM laptops).
- The ~4 GB ISO downloads to your Downloads folder. Verify the file size before using it.
What Is Windows 11 24H2 IoT Enterprise LTSC?
Windows 11 IoT Enterprise LTSC 2024 is Microsoft’s long-term servicing version of the 24H2 release (build 26100). LTSC stands for Long-Term Servicing Channel, and it is built for fixed-function machines — ATMs, medical equipment, industrial control PCs, point-of-sale terminals — where you cannot have features changing under you every six months.
Compared to regular Windows 11 Pro or Home, the LTSC build is genuinely stripped down. There is no Microsoft Store, no Edge browser, no Cortana, no Copilot, no Xbox app, no News and Interests widget, no Phone Link. You get the desktop, File Explorer, the classic Windows utilities, and that is mostly it. For 10 years it only receives security updates and bug fixes — no new features, no UI redesigns.
The evaluation ISO Microsoft hosts is fully featured and activates as a 90-day eval copy on first boot. After 90 days, the system will start reminding you to activate, and eventually start restarting hourly until you enter a valid LTSC license key. Licensing LTSC for a real production machine requires a volume licensing agreement through a Microsoft partner — but for testing, learning, or running it in a VM, the eval ISO is the right starting point.
Heads-up: The product Microsoft lists on the Evaluation Center is technically Windows 11 IoT Enterprise LTSC, not “Windows 11 Enterprise LTSC”. They are the same OS — the IoT branding is just how Microsoft licenses LTSC for general fixed-function use. The ISO works on any PC that meets the regular Windows 11 hardware requirements.
How to Download the Windows 11 24H2 LTSC Evaluation ISO
Step 1: Open the Microsoft Evaluation Center page
Go to the Windows 11 IoT Enterprise LTSC evaluation page on microsoft.com. If you prefer to find it yourself, search Google for Windows 11 24H2 LTSC download and click the result with the microsoft.com/en-us/evalcenter/ URL. Avoid any third-party download site — there is no legitimate reason to grab this ISO from anywhere except Microsoft.
Step 2: Click “Download Windows 11”
On the evaluation page, scroll to the Get started for free section and click the Download Windows 11 button. This opens the registration form. Microsoft requires registration for all evaluation downloads — it is not a paywall, just a form.
Step 3: Fill out the registration form
Complete the form with your first name, last name, business email, company name, job title, country, and phone number. The two marketing checkboxes at the bottom are optional — I leave them blank to avoid the follow-up emails. Microsoft does not verify the company field, but the email should be one you actually check, in case they send the download link there.
Step 4: Choose 64-bit or ARM64 and start the download
After clicking Download Now, you will see a version selector. Pick 64-bit edition for standard Intel/AMD desktops and laptops. Pick ARM64 edition only if you are running this on a Snapdragon-based Copilot+ PC or Surface Pro X — otherwise the ARM ISO will not boot on your hardware. The download starts immediately and is roughly 4 GB. On a 100 Mbps connection that is about 5–6 minutes; on slower links, expect 30 minutes or more.
Tip: Once the ISO is downloaded, check the file size. If it is under 3.5 GB, the download was truncated — delete it and try again. A complete 24H2 LTSC ISO sits around 4.0–4.2 GB.
How to Install Windows 11 24H2 LTSC From the ISO
Once the ISO is downloaded, you have three realistic ways to use it: create a bootable USB for a clean install, mount the ISO and run setup for an in-place upgrade, or attach it to a virtual machine. For most people testing LTSC, a VM is the safest option — you can throw it away when you are done.
Bootable USB (clean install): I recommend using Rufus to create the bootable USB. Rufus also lets you remove the Microsoft account requirement, disable BitLocker auto-encryption, and pre-set the username — useful even on LTSC. If you would rather skip USB drives entirely, my UnattendedWinstall project automates the whole install with an answer file.
In-place upgrade: Double-click the ISO in File Explorer to mount it as a virtual drive, then run setup.exe. This upgrades your current Windows installation to LTSC while keeping your apps and files — useful if you want to convert an existing Windows 11 Pro install to LTSC without reinstalling everything.
Virtual machine: Point your hypervisor (Hyper-V, VirtualBox, VMware Workstation) at the ISO and create a new VM. Allocate at least 4 GB RAM and 60 GB disk. This is the cleanest way to evaluate LTSC without committing your physical machine.
Hardware Requirements and Unsupported PCs
Windows 11 24H2 LTSC has the same baseline hardware requirements as regular Windows 11 24H2: TPM 2.0, UEFI with Secure Boot, a supported 64-bit CPU (8th-gen Intel Core / AMD Ryzen 2000-series or newer), 4 GB RAM, and 64 GB storage. The 24H2 build also introduced a new requirement for the POPCNT CPU instruction — older CPUs (roughly pre-2008) that lack it will fail to boot 24H2 entirely.
If your PC does not meet these requirements, you have options. My Flyby11 guide walks through bypassing the hardware checks during install, and the unsupported hardware upgrade guide covers the broader options for getting 24H2 onto older machines.
Common Issues and How to Fix Them
The download link does not appear after submitting the form. Microsoft’s evaluation site occasionally hangs on the redirect. Refresh the page and resubmit the form — the download nearly always starts on the second attempt. If it still fails, try a different browser (Edge tends to be the most reliable on Microsoft’s own sites).
The download keeps failing or times out. The 4 GB ISO is a single HTTP transfer, so unstable connections can break it. If your browser does not support resume, use a download manager like FDM or run the download in aria2c from PowerShell. Also make sure your antivirus is not scanning the partial file mid-download — Defender is usually fine, but some third-party suites are aggressive enough to corrupt large ISOs.
The ISO will not mount or appears corrupted. Check the file size first — anything under ~3.8 GB is incomplete. If the size looks right but mounting fails, try running certutil -hashfile yourfile.iso SHA256 and compare the hash to one published in a recent LTSC discussion thread. A mismatch means the file is corrupted and needs to be re-downloaded.
“Windows cannot install required files” during setup. This is almost always a USB stick issue — either the stick is failing, or it was formatted incorrectly. Re-create the bootable USB using Rufus with GPT / UEFI partitioning, and use a known-good USB 3.0 drive of at least 8 GB.
Should You Actually Use Windows 11 LTSC?
This is the question I get most often, and the honest answer for the vast majority of home users is no. LTSC is designed for fixed-function machines, not daily-driver PCs. You lose the Microsoft Store, which means installing modern apps (Spotify, WhatsApp, anything UWP) becomes a manual hassle. You lose Edge, which means manually downloading a browser before you can do anything. You lose Windows updates that matter for new hardware support — if you buy a new GPU two years from now, drivers may not behave the same on LTSC.
If your goal is a leaner, faster, less-bloated Windows 11 — without the LTSC trade-offs — you have two better options:
- Winhance — my own free, open-source tool that removes bloat, debloats Edge, disables telemetry, and rolls back the worst of the AI features. It runs on regular Windows 11 Home or Pro and gets you ~80% of the LTSC experience without losing the Store or Edge.
- UnattendedWinstall — my answer-file project that produces a clean Windows 11 install with bloat removed at setup time. You end up with a normal Windows 11 Pro install, just without the junk.
Where LTSC genuinely shines: kiosks, point-of-sale, lab machines, dedicated recording rigs, anything that needs to sit untouched for years. For those, the evaluation ISO is the right place to start.
Frequently Asked Questions
Is the Windows 11 24H2 LTSC evaluation ISO free?
Yes. The ISO itself is a free download from Microsoft’s Evaluation Center and activates as a 90-day evaluation copy automatically. You only need to pay if you want to convert it to a permanent licensed install, which requires a volume licensing agreement through a Microsoft partner — LTSC keys are not sold to individuals on the Microsoft Store.
How long does the LTSC evaluation last?
The evaluation runs for 90 days from installation. After that, Windows starts displaying activation reminders, and eventually the system will reboot every hour until you enter a valid LTSC product key. You can reinstall the eval ISO to reset the 90-day timer, though that is not really a long-term solution.
What is the difference between Windows 11 LTSC and regular Windows 11?
Regular Windows 11 gets feature updates every year (24H2, 25H2, etc.) and includes the Microsoft Store, Edge, Cortana, Copilot, and Xbox app. Windows 11 IoT Enterprise LTSC 2024 skips all of those and only receives security updates for 10 years on the same 24H2 base. It is designed for stability and predictability, not features.
Can I use Windows 11 LTSC for gaming?
Technically yes — games install and run on LTSC. But you lose the Xbox app, Game Bar, and DirectX 12 Ultimate features that ship as Store apps. You also lose easy access to the Microsoft Store version of games like Forza. For gaming, I would stick with regular Windows 11 and use Winhance to remove the bloat.
Do I need a product key during installation?
No. The evaluation ISO does not prompt for a product key during setup — it activates as an evaluation copy automatically. You only need a key if you later want to convert the install to a fully licensed LTSC version, which is done from Settings > System > Activation.
Will LTSC run on a PC that does not meet Windows 11 hardware requirements?
Not by default. The 24H2 LTSC build enforces the same TPM 2.0, Secure Boot, and POPCNT-instruction requirements as regular 24H2. If your hardware is unsupported, you can use my Flyby11 guide to bypass the checks, but the POPCNT requirement is a hard CPU limit — older pre-2008 CPUs simply cannot run 24H2.
