HP ENVY 17 Notebook PC: Can't Activate Windows 8 Pro after a Factory Reset (Hard Disc reformatted).

Hello:

I had to perform a drastic cleanup of the C-drive of my ENVY 17 Notebook and did a Factory Reset. I was able to reload Windows 8 Pro from my recovery USB drive.

However, Windows 8 Pro cannot be reactivated stating that the Product Key is Invalid or Blocked. I understand this is caused by having the OS drive formatted and completely cleaned.

My questions are:

1. Will the HP Recovery Disks (which is available for ordering) be able to help solve the above situation?
2. Will it allow me to reactivate my Windows 8 Pro?
3. Will the HP Recovery Disks/media contain or marked with the proper Windows Product Key?

Thanks,

Rico.
