Microsoft will retire Windows 10 on October 14, 2025, after which it will no longer receive technical support, feature updates, or security patches. Users can upgrade to Windows 11, but not all devices meet its requirements. Microsoft offers an Extended Security Updates (ESU) program for an additional year of security support for a fee. Another option is the Windows 10 IoT Enterprise LTSC edition, which provides a streamlined experience but is not intended for general consumer use and comes with complex licensing requirements. Windows 10 LTSC will receive official support for several years, but as mainstream Windows 10 approaches its end-of-support date, software and driver support may decline. Users with older hardware may consider acquiring a Windows 10 LTSC key to extend device functionality, but should weigh the associated challenges.
