Microsoft is set to officially discontinue Windows 10 on October 14, 2025, urging users to transition to Windows 11, which claims to be up to 2.3 times faster than its predecessor. Approximately 400 million users remain on Windows 10, but the upgrade may be complicated by stringent system requirements and design flaws. Alternatives like Tiny11 and Nano11 have emerged, with Tiny11 designed for older PCs and recently updated to support Windows 11 version 25H2 by removing pre-installed applications. Nano11, a more minimal version, reduces the OS footprint to less than 3 GB and supports any Windows SKU, but once installed, it cannot be modified or updated. Nano11 is primarily intended for testing, development, or embedded use in virtual machines.
