Microsoft recently reminded enterprise customers that the lifecycle of the Windows 10 Enterprise LTSC 2021 operating system is coming to an end. Although mainstream support for Windows 10 ended in October 2025, the LTSC version has continued to receive updates due to its extended lifecycle policy. Currently, the support period for this version is entering its countdown, and Microsoft is urging enterprise IT administrators to plan ahead for migration, as the system will officially end support on January 12, 2027.
