Tools like Cheat Engine or x64dbg can attach to the running PMU Lite process, locate the conditional jump (JE/JNE) that checks for a valid license, and modify it (e.g., change JE to JMP). This temporarily unlocks features until the program restarts.
A patched version of PMU Lite will likely break after an official update. Automatic updates may revert your patches or, worse, detect the tampering and lock you out entirely.
Software-layer patch (OS drivers)
Firmware extraction and offline modification
