Windows 10: storing system-tracking data in UEFI variables

As one comment above notes, make sure you know how to reset this firmware-stored data before you dispose of any such systems.

Interesting, I would have guessed that this data would be stored in UEFI SMM LockBox, but some forms of UEFI variables are also hard to access. Ah, but this is for persistent data…

I’d swear I saw some MacOSX (before change to macOS) components moved from system libraries up into Apple EFI, I wonder if Apple also implements SmmLockBox?
