Windows 10 that keeps receiving security updates until January 2032.

| License term | Lifetime, one-time payment |
| Devices | 1 device (PC, kiosk or thin client) |
| Support | Security updates until Jan 13, 2032 |
| Hardware | No TPM 2.0 needed; suits older PCs |

Here you get one genuine Windows 10 IoT Enterprise LTSC 2021 product key, a permanent license for a single device. This is the long-term servicing edition of Windows 10, version 21H2, and it is the one Windows 10 edition that Microsoft still supports for years to come: security updates continue until January 13, 2032, long after regular Windows 10 Home and Pro stopped receiving them.
LTSC 2021 strips Windows 10 down to the essentials. There are no feature updates, no Microsoft Store and no consumer apps, so the system you set up today is the system you will have in five years. It does not require TPM 2.0, which makes it the practical choice for well-built PCs, industrial computers and kiosks that cannot move to Windows 11. You download the 64-bit ISO from Microsoft, install it and activate it with the key from your order email.
Yes. Windows 10 IoT Enterprise LTSC 2021 is supported until January 13, 2032, even though mainstream Windows 10 support ended on October 14, 2025 and the consumer Extended Security Updates program runs out on October 12, 2027. LTSC editions follow their own fixed lifecycle, so the general Windows 10 deadline does not apply to them.
Be careful with the name, because two LTSC 2021 editions exist. Windows 10 Enterprise LTSC 2021 (without “IoT”) has a five-year lifecycle that ends on January 12, 2027. The IoT edition sold here gets a ten-year lifecycle, which is five more years of patches from the same code base. Our guides to Windows 10 end of support and Windows 10 Extended Security Updates explain the options for other Windows 10 PCs.
It is Windows 10 delivered through the Long-Term Servicing Channel, Microsoft’s release track for devices that must not change. A new LTSC version appears only every few years, and each one is then patched for security and reliability without new features. Compared with Windows 10 Pro, LTSC 2021 contains:
No, and that is intentional. LTSC 2021 ships without the Microsoft Store and without the apps that depend on it. Desktop software that installs from a setup file, such as browsers, Office, CAD packages, PLC tools or point-of-sale suites, works normally. Microsoft does not offer a supported way to add the Store to LTSC, so if you rely on Store-only apps, choose a regular edition such as Windows 11 Pro on hardware that supports it.
| Windows 10 IoT Enterprise LTSC 2021 | Windows 10 Pro | Windows 11 IoT LTSC 2024 | |
|---|---|---|---|
| Security updates | Until Jan 13, 2032 | Ended Oct 14, 2025 | Until Oct 10, 2034 |
| TPM 2.0 needed | No | No | No, optional |
| Feature updates | None | None (final version 22H2) | None |
| Microsoft Store | — | ✔ | — |
| Interface | Windows 10 | Windows 10 | Windows 11 |
| Good fit | Older or validated hardware staying on Windows 10 | Legacy PCs that run offline | New fixed-purpose deployments |
If your fleet runs full Windows 10 Enterprise with feature updates rather than LTSC, our Windows 10 Enterprise key is the matching product, though its support has ended along with the rest of mainstream Windows 10.
Is LTSC good for gaming? It can run games from desktop launchers, but missing Store components break Game Pass and Xbox app titles, so it is not the edition to buy for a gaming PC.
| Component | Minimum | Comfortable |
|---|---|---|
| Processor | 1 GHz, 64-bit | Dual-core 2 GHz or newer |
| Memory | 2 GB | 4–8 GB |
| Storage | 32 GB | 64 GB+ SSD |
| TPM | Not required | TPM 1.2 or 2.0 if you plan to use BitLocker without a USB key |
| Firmware | Legacy BIOS or UEFI | UEFI with Secure Boot |
| Graphics | DirectX 9, WDDM 1.0 driver | Any current GPU |
These modest requirements are why LTSC 2021 is often used to keep older business PCs and industrial boxes patched. To create the installer, follow our bootable USB guide or the Rufus steps in the How to Download tab.
Microsoft normally supplies IoT Enterprise to device manufacturers, preinstalled on finished hardware, and sells non-IoT LTSC through volume licensing. Neither route suits a business or individual with a single machine, which is why we sell one key for one device at the price shown at the top of this page. Moving an existing PC to LTSC is a clean installation: Microsoft does not support an in-place switch from Windows 10 Home or Pro to the long-term servicing channel, so back up your files, install from the LTSC ISO and then reinstall your applications. IoT Enterprise is intended for dedicated, fixed-purpose devices, so for a general home or office computer a regular edition is the better match.
Both keep a Windows 10 machine patched, but they work very differently. Extended Security Updates is a paid add-on that Microsoft sells one year at a time for regular Windows 10 editions; the consumer program closes on October 12, 2027, and organizations pay again for every additional year they stay enrolled. LTSC 2021 is a one-time purchase that already includes security updates through January 2032, more than five years beyond today, with no enrollment or renewal to manage. The trade-off is the clean install and the absence of the Store, which rarely matters on a dedicated device. For a PC that will keep running Windows 10 for the rest of its service life, the LTSC route is usually simpler and cheaper overall.
You pay once, and the device stays activated through reinstalls for as long as you use it. Security updates arrive until January 13, 2032; after that date the system keeps working and stays activated, but without new patches. The key covers LTSC 2021 only. When the time comes to move a device to Windows 11, the Windows 11 IoT Enterprise LTSC 2024 key is a separate license. Replacing the motherboard is treated as a new device.
Many sites sell LTSC keys with no after-sale support, so look at what happens when something goes wrong. Makers Unity LLC, a Microsoft partner, operates Kymakers and backs every order with a 180-day refund for unredeemed keys, a free replacement if the key stops working through no fault of yours, and free help with online or phone activation. Any store can be measured against the checklist in our article is it safe to buy cheap Microsoft license keys?.

Very happy with how this went. Good price for a genuine licence. Exactly what I was after. All the features I needed are there and working fine. Would buy from kymakers again.
Received the code pretty quickly after the payment went through. Activated without a hitch. Everything validated fine. Recommended.
Solid purchase overall. Couldn’t justify the full retail price — this was a much smarter option. No issues so far after a few weeks of use. Would buy from kymakers again.
The download link and key showed up in my email really fast. Followed the instructions on the site and it activated without problems. Will definitely come back when I need another licence.
Very happy with how this went. Honestly great value compared to buying from Microsoft directly. All the features I needed are there and working fine. Already recommended it to a colleague.
