cpu-parking-disabler

Shows how many cores Windows has parked right now and the four power
settings behind it, then sets Core Parking Min Cores (CPMINCORES /
CPMINCORES1) to 100 and Energy Performance Preference (PERFEPP / PERFEPP1)
to 0 on the active power scheme, for AC and DC, and shows the parked-core
count again so the effect is visible on screen.

Supports hybrid Intel CPUs with E-cores, 12th gen and newer (separate
P-core/E-core settings), and non-hybrid CPUs (AMD Ryzen, older Intel), where
Windows ignores the Class 1 (P-core) settings. X3D Ryzens with 3D V-Cache on
one of their two CCDs (7900X3D, 7950X3D, 9900X3D, 9950X3D, and the laptop
7945HX3D and 9955HX3D) get a warning and a prompt first: in
Windows Game Mode, which the Xbox Game Bar turns on when it detects a game,
AMD's chipset driver parks the other CCD so the game stays on the cache,
and this tweak defeats that. The 9950X3D2, with 3D V-Cache on both CCDs,
gets a note only.

The previous values are written to parking_undo_<stamp>.json next to the
script before anything changes; -Undo puts back the values you had set
yourself and returns the rest to Windows' default. The script relaunches
itself as Administrator when needed.
