Power fluctuations apparently resulted in damage to the USB flash drive that ESXi 6.7 free was running from. Created a new flash drive and was able to use it to recover/re-register four of six VMs. My Windows XP and Windows 8.1 VMs were marked as invalid when I tried to re-register them and I am stuck. The “unregister” command is greyed out and I haven’t a clue what to try now. Is the “unregister” command, in fact, not available in the free version?
