I appreciate you asking for a review, but I need to give you a first:

1. Anti-Cheat Hell: Some games (Valorant's Vanguard, Genshin Impact, CoD's Ricochet) may flag modified OS files as "untrustworthy system." You risk a shadowban or a full HWID ban.
2. Missing Dependencies: Many custom ISOs strip out Microsoft Visual C++ runtimes, .NET Framework, or DirectX components. You will spend hours reinstalling them manually.

Custom ISOs often include registry tweaks for high-resolution timers (HPET), MSI mode for GPU interrupts, and CPU core parking disabling. best custom windows 10 iso for gaming
