EN EN Windows 11 LTSC Explained: Enterprise LTSC 2024 or Windows 11 IoT Enterprise LTSC—Who Should Consider the Long-Term Support Version

Windows 11 LTSC: Ten Years Without Feature Updates—But Still Not Intended for Every PC

Windows 11 LTSC is a long-term support version of Windows 11 whose feature set is frozen at release and which, thereafter, receives only security and quality updates for years to come. It is currently available in two editions: Windows 11 Enterprise LTSC 2024, with updates through October 9, 2029, and Windows 11 IoT Enterprise LTSC 2024, with updates through October 10, 2034.

Microsoft intends
both editions for devices designed to perform a single task unchanged over a long period of time: cash registers, machine controls, medical devices, and information kiosks. For a standard office or home PC, Windows 11 Pro or Home is the better choice in most cases. The following answers explain why, and in which cases LTSC is still the right choice.

Why isn’t Windows 11 LTSC intended for standard office PCs, even though it seems more streamlined and stable?

Because LTSC’s stability stems from the fact that nothing changes over the years—and that’s precisely what becomes a problem over time on a workstation PC. Microsoft itself states that the Long-Term Servicing Channel is not intended for the majority of PCs in an organization, but rather for specialized devices that perform a critical task and rely very little on external apps. An office PC, on the other hand, constantly needs new versions of browser extensions, video conferencing software, printer drivers, and specialized applications. Manufacturers of such software primarily test their products against the regular Windows versions, and Microsoft points out that support for LTSC by apps, bundled programs, and the Microsoft Store may be limited. What seems streamlined during installation—because the Store and many consumer apps are missing—becomes a shortcoming after two or three years when a needed application no longer supports LTSC.

What exactly is Windows 11 LTSC 2024?

The current long-term support version was released on October 1, 2024, and technically corresponds to Windows 11 Version 24H2, Build 26100. While Windows 11 Home and Pro receive a feature update every year with new features and a revised user interface, LTSC remains at this version until the end of support. During this time, Microsoft provides only monthly security and quality updates. New LTSC versions are released approximately every three years; upgrading to the next version requires a new license. Older versions, up to Windows 10 Version 1607, were called LTSB (Long-Term Servicing Branch), and they still appear under this name in forums and guides.

What is the difference between Enterprise LTSC and IoT Enterprise LTSC?

Technically, both editions are the same version of Windows; Microsoft explicitly states that IoT Enterprise is binary equivalent to Windows Enterprise. The differences lie in three areas. First, the support period: Enterprise LTSC 2024 receives updates through October 9, 2029—a total of five years—while IoT Enterprise LTSC 2024 receives updates through October 10, 2034—a total of ten years. Second, the intended use: The IoT edition is licensed and distributed for single-purpose devices; the license terms include specific permissions and restrictions for this purpose. Third, the hardware: For IoT Enterprise LTSC, Microsoft specifies lower optional minimum requirements for device manufacturers, which do not exist for Enterprise LTSC.

How long will the long-term support version receive security updates?

Windows 11 Enterprise LTSC 2024 will receive updates through October 9, 2029, and Windows 11 IoT Enterprise LTSC 2024 through October 10, 2034. By comparison: For Windows 11 Home and Pro, each annual release receives updates for 24 months; version 25H2, for example, will be supported until October 12, 2027. In these editions, a PC remains supported only if it installs the next feature update every year. With LTSC, this step is completely eliminated; instead, support ends on a fixed date, and after that, the device requires a new LTSC version with a new license or a different edition.

What is missing from LTSC compared to Windows 11 Home and Pro?

The most noticeable difference in everyday use is the absence of the Microsoft Store. Programs that a manufacturer distributes exclusively through the Store cannot be installed on LTSC in the usual way. In addition, many preinstalled consumer apps are missing, and new Windows features that Microsoft introduces with the annual updates never make it to LTSC. Internet Explorer is no longer included in Enterprise LTSC 2024, though IE Mode remains in the browser for legacy web applications. WordPad has been missing from all Windows editions since version 24H2, not just LTSC. The security and management features of the Enterprise edition—such as BitLocker, Credential Guard, and AppLocker—are, however, fully available.

Which new features of the regular Windows 11 versions are intentionally omitted in LTSC—and whether you would miss them in your daily routine—is a question in itself, one that is only touched upon here.

of the Key Pros and Cons What Windows 11 improves upon compared to Windows 10, where it limits users, and for whom the switch is worth it.

Does Windows 11 IoT Enterprise LTSC also run on PCs without TPM 2.0?

For the IoT edition, Microsoft specifies not only the preferred minimum requirements but also an optional lower threshold where TPM 2.0 and Secure Boot are not mandatory, and where a BIOS is permitted instead of UEFI. This optional lower threshold is explicitly intended for device manufacturers building specialized devices with a fixed, tailored use case. At the same time, Microsoft warns that the absence of a TPM may interfere with software the user will need later, such as for encryption or logging in via Windows Hello. Microsoft does not specify any such exceptions for Enterprise LTSC 2024. Anyone who chooses IoT LTSC solely to continue operating an old office PC without a TPM is using a rule intended for device manufacturers for a purpose for which it was not written.

How exactly do Windows 11 Pro, Enterprise, and the two LTSC editions differ?

The table compares the four editions that buyers of Windows 11 for business and specialized devices can choose from in practice. Windows 11 Home is not included because it lacks domain joining and BitLocker and is therefore not an option for specialized devices. The Windows 10 predecessors are covered in a separate section below.

Criterion	Windows 11 Pro	Windows 11 Enterprise	Enterprise LTSC 2024	IoT Enterprise LTSC 2024
Annual Feature Updates	✓	✓	✕	✕
Support per version	24 months	36 months	Through October 9, 2029	Through October 10, 2034
Microsoft Store	✓	✓	✕	✕
Credential Guard, AppLocker	Limited	✓	✓	✓
TPM 2.0 required	✓	✓	✓	Optional
Intended Use	Office, Home	Managed company PCs	Specialized devices	Single-purpose devices

“Limited” in Windows 11 Pro means that Credential Guard and full AppLocker control are part of the feature set of the Enterprise editions, while Pro covers only a portion of the security policies. “Optional” for the TPM in the IoT Edition refers to the minimum requirement Microsoft sets for device manufacturers; TPM 2.0 is still recommended there as well. The 24- and 36-month periods refer to each annual release of Pro and Enterprise; users who install the annual feature update will continue to receive updates indefinitely.

Can I use LTSC on my home PC?

Technically, LTSC can be installed on a home PC, but for the typical home user, it’s rarely a good choice. Without the Microsoft Store, you’ll miss out on apps available exclusively there, and the Xbox app—which includes many PC games—is also obtained through the Store. The support period sounds tempting, but Windows 11 Home and Pro remain supported for just as long with the annual free feature updates, without requiring a new license for the successor version later on. In the case of the IoT Edition, its license terms are designed for devices with a specific purpose. Anyone who wants to use it on a standard home PC should check the terms of use themselves beforehand. For everyday use—browsing, Office, photos, and games—Windows 11 Home remains the best choice.

Can I use LTSC in the office?

For individual specialized devices in the office, yes; for standard workstations, generally no. Suitable use cases include a reception terminal, a PC connected to a measuring device, a label-printing station in the warehouse, or a computer running certified industry-specific software that would need to be revalidated after every feature update. For workstations with email, Teams, a browser, and rotating applications, the Windows 11 Professional OEM Key ⧉ is the right license. Pro includes BitLocker, Remote Desktop as a host, and domain joining, and receives new features every year. For a device intended to perform the same task unchanged for ten years, however, Pro is the less stable choice, because every feature update can change the interface and behavior.

Whether Home or Pro is sufficient for a specific office depends on the network, encryption, and remote access requirements—and is a separate consideration that goes beyond the LTSC question.

What devices is Windows 11 IoT Enterprise LTSC intended for?

Microsoft lists typical devices as ATMs, point-of-sale systems, control computers in industrial automation, thin clients, medical devices, digital signage, and kiosk systems. What they have in common is that they perform a specific task, have often undergone certification or validation, and are not permitted to receive feature updates for many years. For such devices, the Windows 11 Enterprise IoT LTSC 2024 Key ⧉ is the appropriate edition, because the ten years of updates through October 10, 2034, cover the typical lifespan of a machine or point-of-sale system. Kiosk features such as Assigned Access, which restrict a computer to a single application, are included. The IoT Edition is not suitable as a replacement for Windows 11 Pro on a workstation PC because its licensing terms are tailored to devices with a fixed purpose.

When is Enterprise LTSC 2024 the better choice than the IoT Edition?

When a company integrates specialized workstations into an existing Windows Enterprise environment and a five-year support period ending October 9, 2029, aligns with the devices’ replacement cycle. Typical examples include lab computers, control rooms, or production test stations that are managed by IT like other company devices but are not intended to undergo frequent changes. The Windows 11 Enterprise LTSC 2024 Key ⧉ is ideal for precisely this scenario. For devices planned to be in use significantly longer than until 2029, it is not sufficient; in that case, the IoT Edition or a later reinstallation with the next LTSC version should be planned.

What do I get with a Windows 11 LTSC key?

You always receive a license key for the long-term support version for a specific edition and a specific version—currently Enterprise LTSC 2024 or IoT Enterprise LTSC 2024. It does not entitle you to upgrade to the next LTSC version later; a new license is required for that. It also does not include annual feature updates; instead, it remains at the 24H2 level until the end of support for that version. If you want Enterprise features but also want the ongoing updates from Windows 11, you don’t need LTSC—you need the regular Windows 11 Enterprise key ⧉. It includes Credential Guard, AppLocker, and advanced management features, and receives an annual feature update with 36 months of support. However, it is the wrong edition for a device that must remain unchanged for years.

Why is the edition called “IoT” even though it’s a full version of Windows?

“IoT” here does not stand for a stripped-down system for small sensors, but rather for the distribution and licensing channel for devices with a fixed purpose. Windows 11 IoT Enterprise LTSC 2024 is binary-identical to Windows 11 Enterprise and offers the same programs, drivers, and management tools. A second naming pitfall concerns the word “Enterprise”: Windows 11 Enterprise without the LTSC suffix is a regular edition with annual feature updates, not a long-term support version. And in the store, you’ll also find the IoT edition listed as “Enterprise IoT LTSC”—this refers to the same product as Microsoft’s “IoT Enterprise LTSC.”

Is Windows 10 LTSC 2021 still worth it today?

Windows 10 Enterprise LTSC 2021 is no longer worth it for new installations because its support ends on January 12, 2027. The situation is different for Windows 10 IoT Enterprise LTSC 2021, which will receive updates until January 13, 2032. This is relevant for existing machines and control computers whose hardware or software is not compatible with Windows 11 and that are intended to run unchanged until the end of their service life. In this case, the Windows 10 Enterprise IoT LTSC 2021 key ⧉ is worth considering. It is the wrong choice for a new computer, however, because Windows 11 IoT Enterprise LTSC 2024 will receive support for nearly three years longer.

Does Office run on the long-term support version of Windows 11?

Yes, Microsoft explicitly lists the 2024 long-term support version of Windows 11 as a supported operating system for Office LTSC 2024. Like Windows LTSC, this version of Office is intended for environments that cannot receive feature updates and is therefore suitable for specialized workstations. Anyone wishing to use other versions of Office on LTSC should first check the official compatibility list for that specific combination, as Microsoft determines support on a per-Office-version basis.

A separate overview lists
which Office versions are approved for which Windows versions, but that would go beyond the scope of this answer.

What does the Long-Term Support (LTSC) version not cover?

LTSC ensures the long-term stability of an operating system for years, but not the environment surrounding it. Microsoft supports an LTSC version on the hardware that was current at the time of its release. Processors and chipsets released years later may no longer be supported, which is why Microsoft recommends planning for replacement parts for the entire duration of use. Third-party software may discontinue support for an older LTSC version sooner than Microsoft itself. And the support period ends abruptly: After October 9, 2029, or October 10, 2034, respectively, there will be no more security updates for the respective edition; no extension has been announced for these versions.

Which edition is right for which scenario?

The choice depends less on the size of the company than on whether the device can be modified and how long it will remain in use.

Your situation	Suitable Edition	Reason
Home PC for everyday use and gaming	Windows 11 Home	Includes the Store and new features.
Office workstation	Windows 11 Pro	Domain, BitLocker, ongoing updates.
Managed corporate PCs with high security requirements	Windows 11 Enterprise	Enterprise-level security with feature updates.
Specialized workstation, supported through 2029	Enterprise LTSC 2024	Five years without feature changes.
Point-of-sale, kiosk, machine control	IoT Enterprise LTSC 2024	Ten years of updates, licensed for a specific purpose.
Existing control systems without Windows 11 support	Windows 10 IoT Enterprise LTSC 2021	Updates through January 2032.

Windows 11 LTSC: Is the long-term version right for me?

The key question isn’t how long Windows receives updates, but whether the device is allowed to change during that time. If it must function exactly the same way for years—because a machine, a point-of-sale system, or certified software depends on it—LTSC is the right choice: IoT for ten years and Enterprise for five. If a person is using it for email, a browser, and various programs, Windows 11 Pro or Home is the better solution because they’ll continue to receive free feature updates for just as long, and the software running on them will evolve over time.
