While "Micro 10" is incredibly fast, it is a third-party custom build. This means it does not have official documentation or support from Microsoft. It is perfect for dedicated gaming machines, legacy laptops, or secondary PCs where you want maximum speed. However, because it often disables Windows Update and removes Windows Defender by default to save resources, it may require manual security management.
