Microsoft’s announcement that regular support for Windows 10 will end in October 2025 has stirred significant discussion among users whose devices do not meet Windows 11’s stringent hardware requirements. As many PCs worldwide still rely on Windows 10, the question arises: what are the feasible options for these users, particularly those who want to avoid investing in new hardware immediately? A lesser-known but practical escape from this “end of support” predicament lies in the Windows 10 Long Term Servicing Channel (LTSC) editions, which offer extended update support and a streamlined Windows experience that can extend as far out as 2032.
Windows 10, launched in 2015, has maintained dominance as the operating system of choice for a significant portion of PCs globally. However, with Microsoft planning to end free security updates and patches on October 14, 2025, users face increasing security risks. Unsupported systems typically become easy targets for cyberattacks due to emerging vulnerabilities not being patched. Additionally, lack of ongoing software updates means eventual incompatibility with new applications and drivers, contributing to performance and stability issues.
The straightforward advice from Microsoft has been to upgrade to Windows 11, which promises enhanced security features like TPM 2.0 and Secure Boot, a modernized user interface, improved productivity tools, and better overall system performance. However, Windows 11 comes with tighter hardware restrictions, notably requiring relatively recent CPUs and TPM 2.0 modules. Approximately 400 million devices worldwide fall short of these requirements, leaving many users effectively locked out of the upgrade path without buying new computers.
Running Windows 10 after the end-of-support date without ESUs risks exposure to unpatched security holes, software incompatibilities, and missing out on critical performance enhancements. Furthermore, Microsoft is increasing push notifications and even forced updates designed to steer users toward Windows 11 or new hardware purchases. This marketing approach, aggressive as it may be, highlights how Microsoft is prioritizing a shift across its ecosystem rather than maintaining legacy platforms indefinitely .
The latest LTSC release is Windows 10 Enterprise LTSC 2021, based on the 21H2 version of Windows 10, supported until January 12, 2027. There is also the IoT Enterprise LTSC 2021 variant, boasting extended support until January 13, 2032. Unlike the standard consumer editions, these LTSC versions strip out many “modern” apps and bloatware such as the Microsoft Store, OneDrive, Weather, and Mail apps, leaving mostly traditional Windows experiences with Edge browser and Windows Defender antivirus intact. This minimalist build is preferred in contexts requiring lean, stable operation with fewer background services and distractions.
Crucially, the LTSC releases do not upgrade to new feature versions over time. You remain on the same base version — 21H2 for Windows 10 LTSC 2021 — for the duration of its support, eliminating the disruptions and compatibility concerns associated with Windows 10’s semi-annual feature updates. However, to move to a newer Windows 10 build when offering expires, a full reinstallation is required. Since Windows 10 22H2 is the final feature update to Windows 10, this limitation may be less significant compared to earlier Windows 10 versions .
The licensing process can be a hurdle for individual or small-scale users. Volume Licensing agreements typically target organizations rather than single users, although it is possible to negotiate smaller licenses, sometimes even for as few as five devices. Some unofficial download portals distribute LTSC ISOs, but caution is advised with third-party sources due to potential legality and security risks.
Activation is another consideration: LTSC editions require enterprise keys and cannot activate with consumer Windows 10 license keys, though workarounds exist (the legality of which is questionable). For users willing to invest in proper licensing, LTSC offers a cost-effective alternative compared to purchasing new hardware solely for Windows 11 compatibility.
Security-wise, LTSC editions do receive antivirus and key security updates, ensuring you’re protected without the risks introduced by frequent OS changes. Enterprises leverage this stability for mission-critical devices, medical equipment, kiosks, industrial PCs, and environments where constant change is untenable.
One notable difference between the LTSC editions is language support. The IoT Enterprise LTSC version focuses mainly on US English for system language, while the standard Enterprise LTSC supports 38 languages, offering broader international usability. Additionally, Windows 11 also has an IoT Enterprise LTSC edition, which has lower system requirements than Windows 11's mainstream editions and may be suitable for hardware-constrained scenarios .
Reinstallation to upgrade to a newer LTSC version or mainstream Windows version is labor-intensive and time-consuming. Additionally, the strict licensing restrictions make LTSC a less accessible option for the general public.
Further, for home or gaming users, the stripped-down nature and lack of consumer apps may be a disadvantage rather than an advantage. Microsoft’s roadmap does not indicate LTSC editions will see any new variants after Windows 10 21H2 LTSC, though there might be LTSC releases based on Windows 10 22H2 in the future. There are also unofficial “remix” versions of LTSC, such as Tiny11 or Windows X-Lite, but these are community or third-party projects with their own legal and security caveats .
Linux-based operating systems, especially lightweight distributions, remain an alternative for breathing new life into older hardware. Distributions like Linux Mint, Zorin OS, or lightweight Windows-like builds can transform older PCs into usable systems with full security patching. For many, this represents a cost-effective, supported route outside the Windows ecosystem.
While not targeted at mainstream consumers, LTSC provides an enterprise-grade option for preserving Windows 10 on existing hardware without the pressure of forced feature upgrades or the immediacy of costly hardware replacement. The key challenges are licensing costs, activation complexities, and the need for manual management of OS upgrades.
Ultimately, LTSC is a strategic tool for prolonging Windows 10 usage safely, especially for professionals and power users who prioritize stability and extended support over shiny features and app ecosystems. For general users, extended security updates and gradual hardware refresh remain the main options going into the post-Windows 10 era.

Approximately 400 million devices worldwide fall short of these requirements, leaving many users effectively locked out of the upgrade path without buying new computers.
What About Staying on Windows 10?
For those whose PCs cannot officially run Windows 11, continuing with Windows 10 is possible but not without challenges. Microsoft is offering an Extended Security Updates (ESU) program that provides critical security patches for one year beyond October 2025 for a fee (roughly $30 per device for home users). While this extends security coverage temporarily, it is a stopgap rather than a long-term solution. Business users can extend support further, but at increasing costs over three years, making ESUs expensive as a mass strategy.Running Windows 10 after the end-of-support date without ESUs risks exposure to unpatched security holes, software incompatibilities, and missing out on critical performance enhancements. Furthermore, Microsoft is increasing push notifications and even forced updates designed to steer users toward Windows 11 or new hardware purchases. This marketing approach, aggressive as it may be, highlights how Microsoft is prioritizing a shift across its ecosystem rather than maintaining legacy platforms indefinitely .
Enter Windows 10 LTSC: A Hidden Lifeline
Amidst these challenges, the Windows 10 Long Term Servicing Channel (LTSC) editions present a compelling alternative for users who want to stick with Windows 10 but avoid fast-paced feature updates and potential compatibility headaches. Originally designed for enterprises and specialized environments where system stability is paramount, LTSC versions do not receive regular feature updates beyond their initial release. Instead, they receive only essential security and quality updates, which extends support longevity while maintaining a stable experience.The latest LTSC release is Windows 10 Enterprise LTSC 2021, based on the 21H2 version of Windows 10, supported until January 12, 2027. There is also the IoT Enterprise LTSC 2021 variant, boasting extended support until January 13, 2032.

However, to move to a newer Windows 10 build when offering expires, a full reinstallation is required. Since Windows 10 22H2 is the final feature update to Windows 10, this limitation may be less significant compared to earlier Windows 10 versions .
How to Access and Use LTSC Editions
Windows 10 LTSC editions are not openly available on mainstream consumer download channels. They are designed primarily for enterprise deployment, requiring volume licenses or specific channel access. Evaluation ISO files are available for trial purposes, but these are time-limited. For full deployment, an enterprise product key is necessary, as standard Windows 10 Home or Pro licenses do not activate LTSC editions.The licensing process can be a hurdle for individual or small-scale users. Volume Licensing agreements typically target organizations rather than single users, although it is possible to negotiate smaller licenses, sometimes even for as few as five devices. Some unofficial download portals distribute LTSC ISOs, but caution is advised with third-party sources due to potential legality and security risks.
Activation is another consideration: LTSC editions require enterprise keys and cannot activate with consumer Windows 10 license keys, though workarounds exist (the legality of which is questionable). For users willing to invest in proper licensing, LTSC offers a cost-effective alternative compared to purchasing new hardware solely for Windows 11 compatibility.
LTSC Editions Versus Mainstream Windows 10
The LTSC variants offer a fundamentally different user experience. By omitting the Windows Store and universal Windows platform apps, they appeal to users seeking minimalism and stability over the shiny new. While this might seem like a drawback to casual consumers accustomed to the convenience of modern app ecosystems, for power users and professionals, the decreased system bloat and attack surface are distinct advantages.Security-wise, LTSC editions do receive antivirus and key security updates, ensuring you’re protected without the risks introduced by frequent OS changes. Enterprises leverage this stability for mission-critical devices, medical equipment, kiosks, industrial PCs, and environments where constant change is untenable.
One notable difference between the LTSC editions is language support.

Additionally, Windows 11 also has an IoT Enterprise LTSC edition, which has lower system requirements than Windows 11's mainstream editions and may be suitable for hardware-constrained scenarios .
Risks and Caveats in Choosing LTSC
LTSC is not a consumer product and does carry some limitations and considerations. Since LTSC does not receive feature updates, you will miss out on new Windows enhancements and improvements released to the broader Windows 10 and 11 user bases after your version's release. Also, software that relies on newer Windows APIs or features might face compatibility issues if it requires the latest OS features.Reinstallation to upgrade to a newer LTSC version or mainstream Windows version is labor-intensive and time-consuming. Additionally, the strict licensing restrictions make LTSC a less accessible option for the general public.
Further, for home or gaming users, the stripped-down nature and lack of consumer apps may be a disadvantage rather than an advantage. Microsoft’s roadmap does not indicate LTSC editions will see any new variants after Windows 10 21H2 LTSC, though there might be LTSC releases based on Windows 10 22H2 in the future. There are also unofficial “remix” versions of LTSC, such as Tiny11 or Windows X-Lite, but these are community or third-party projects with their own legal and security caveats .
Alternative Paths: Bypassing Windows 11 or Transitioning to Linux
Users whose hardware fails Windows 11’s rigorous requirements might be tempted to bypass the compatibility checks and install Windows 11 anyway. While technically feasible, this approach often leads to instability, future update failures, or permanent incompatibility with Microsoft’s patching infrastructure. Notably, some CPUs lacking certain instruction sets like SSE 4.2 saw update failures, highlighting risks inherent in this strategy.Linux-based operating systems, especially lightweight distributions, remain an alternative for breathing new life into older hardware. Distributions like Linux Mint, Zorin OS, or lightweight Windows-like builds can transform older PCs into usable systems with full security patching. For many, this represents a cost-effective, supported route outside the Windows ecosystem.
Conclusion: LTSC as a Strategic Option for End of Windows 10 Support
For users and organizations unwilling or unable to upgrade to Windows 11 or buy new hardware by 2025, Windows 10 LTSC editions offer a unique escape hatch. They combine extended security update lifecycles (up to seven years or more with IoT Enterprise LTSC 2021), a bloat-free experience, and stable software environments tailored for long-term use.While not targeted at mainstream consumers, LTSC provides an enterprise-grade option for preserving Windows 10 on existing hardware without the pressure of forced feature upgrades or the immediacy of costly hardware replacement. The key challenges are licensing costs, activation complexities, and the need for manual management of OS upgrades.
Ultimately, LTSC is a strategic tool for prolonging Windows 10 usage safely, especially for professionals and power users who prioritize stability and extended support over shiny features and app ecosystems.
