21h2 Best: Atlas Os

Atlas OS 21H2 delivers genuine performance improvements by stripping Windows 10 to a minimal kernel + gaming runtime. However, this comes at the cost of removing nearly all modern security mitigations. It is suitable only for advanced users who understand the risks and operate in controlled, offline, or ephemeral environments. For general use, standard Windows 10 with Game Mode and selective debloating scripts (e.g., O&O ShutUp10) provides a safer compromise.
