Windows 10 Enterprise LTSC 2021 3in1 FR – February 2026 is a professional version of Windows 10 designed for enterprise environments requiring stability, performance and long-term support.
This LTSC (Long-Term Servicing Channel) edition receives only security and stability updates, without frequent additions of new features, making it ideal for critical workstations, industrial environments, or sensitive infrastructures.
The 3in1 designation generally indicates that it groups three variants into a single installation image (e.g., different architectures or Enterprise editions).
French version (FR), updated until February 2026 with the latest cumulative fixes.
These ISOs include the following versions:
– Windows 10 Enterprise LTSC 2021
– Windows 10 Enterprise LTSC 2021 Optimized
– Windows 10 Enterprise LTSC 2021 Optimized v2
Following the latest cumulative update, we are now on v21h2 build 19044.6937
The goal of this ISO is to offer a choice between these 3 more or less optimized versions…
This also saves time for those who frequently need to install Win10 LTSC.
(as up-to-date as possible)!
And in case of a bug, it is now possible to uninstall the latest monthly update!
Basically, in LTSC (by default):
– No Cortana* (some files are present…)
