W10 wouldn't use that code. And if the OS is deeply damaged you may have to use Toshiba's recovery discs.
As to useless I find that unless I pay they are useless.
Let's hear more about:
1. Which Windows.
2. What laptop.
3. If you can order up recovery media.
4. If you need to save files since some folk either don't need to or forgot to backup what they can't lose.
I have had my laptip for a while, i think my littlenone has ripped the windows sticker from the back for the key.
But it wont let me activate windows with error code 0x8007232B
