Buy Windows 11 Enterprise LTSC 2021 (used)
In 2019, Microsoft discontinued the LTSB branch and renamed it LTSC (Long Term Servicing Channel), which means it has been integrated into the Semi-Annual Channel. At Software ReUse, you can already purchase the successor to Windows 10 Enterprise LTSC used—and save a lot of money!
The LTSC version is a “fixed,” stripped-down version of Windows that does not include any new features. This naturally results in fewer entry points for malware. With LTSC, Microsoft is deliberately focusing on stripped-down releases that receive security updates for only 5 years, rather than 10, compared to the previous version.
In 2019, Microsoft consolidated the “Current Branch” (CB), the “Current Branch for Business,” and the “Long Term Servicing Branch” (LTSB) into the new “Semi-Annual Channel” (SAC). LTSC is thus the successor to LTSB, which was released in the 2015 and 2016 versions.
LTSC stands for “Long Term Servicing Channel” and is an update channel reserved exclusively for business customers that previously offered long-term support (5 years of mainstream support + 5 years of extended support); however, since Windows 10 Enterprise LTSC, this support has been limited to just 5 years. Unlike the Professional version, LTSC is rolled out without preinstalled apps (such as Cortana, the Edge browser, the Windows Store, etc.). Unlike the Windows Professional version, the version installed receives only security updates, not feature updates.
Microsoft promises to release new versions every 2 to 3 years.
Microsoft recommends this stripped-down system for specific scenarios, such as plant control systems, ATMs, or point-of-sale systems. However, there are also companies that deliberately choose to use LTSC versions on their end-user devices.
There are no driver updates, so new hardware components cannot be installed. Please be sure to test your hardware on a test system beforehand to verify that it is supported. You can also check whether the more affordable previous versions, LTSB 2015 or 2016, are suitable.
The Software ReUse team will be happy to assist you!
LTSB was renamed LTSC in 2019. Therefore, Windows 10 Enterprise is only available in the LTSC version.
Windows 10 Enterprise, on the other hand, has also been released in the LTSB and LTSC versions.
Windows 11 Enterprise LTSC can only be purchased through volume licensing agreements, such as Select and Enterprise Agreement. It is much easier and more cost-effective to purchase a used license, which includes the same usage rights as a new license and is significantly more affordable.
Windows 11 Enterprise LTSC is always licensed by device when purchased. This means you must purchase a license for each device on which it is installed.
All LTSC versions may also be installed as older versions of Windows, such as LTSB, Windows 8 Enterprise, or Windows 7 Enterprise. However, thanks to down-edition rights, they may also be installed as Windows 11 Professional.

Legal Notices – Used Software
Used Windows 11 Enterprise LTSC Licenses with Documentation
With Software ReUse, you will receive, along with the product key for the expired software, detailed documentation outlining the terms of use for its intended purpose. We provide you with all the information you need to prove exhaustion of rights, even in the event of an audit by the software manufacturer. This includes details about the previous owner and their declaration of cancellation.
We document how the software was originally placed on the market, what compensation the rights holder received for this, the scope of the right of use granted by the rights holder, and whether updates are included. Our software thus not only meets the requirements of the European Court of Justice (Judgment C-128/11), but also the conditions established by the German Federal Court of Justice (BGH).
Proof of exhaustion
Windows 10 Enterprise LTSC licenses, as offered by Software ReUse, are considered “exhausted” software in the legal sense. After verifying the software and ensuring the licenses have been transferred in compliance with the law, we are permitted to sell the software. As the buyer, you have the same rights as you would with new software. This saves you up to 75% off the list price.
We purchase the licenses we offer from other companies that either no longer need them or are switching to different software. These are often what are known as volume licenses. In this licensing model, the software is authorized for use on multiple workstations or computers. As a buyer, you receive no compromises whatsoever with used licenses compared to new software, and you are entitled to regular security updates and support. If you’re interested, learn more about used software.
We provide personal consultation.
