When a YubiKey is used with the YubiKey Minidriver for the first time, the YubiKey Minidriver checks to ensure default values are not being used for the management key and the PIN Unblock Code (PUK). If the default values are in use, the YubiKey Minidriver will upgrade the Management key to a protected value and block the PUK. A blocked PUK will prevent the PIN Unblock function from being active.
To prevent the PUK from being blocked, the local registry must be configured prior to setting up keys.
Key: HKLM\Software\Yubico\ykmd
Value: BlockPUKOnMGMUpgrade (DWORD) - 0 turns off the PUK block feature, any other value enables it
