Hi, I bought an intel nuc NUC7i5BN from a local vendor, the pc was assembled by the vendor and the same for the OS(installed).
I just wanted to put my custom bios according to this guide:
https://www.intel.com/content/www/us/en/support/articles/000023875/mini-pcs.html Create a Custom Logo or Splash Screen on Intel® NUC
after following every step, and a couple of restarts later the windows activation stopped working this happened on 5 different pcs(I made the same operation on 5 NUC7i5BNs)
the bios screen was updated with my logo btw.
I contacted Microsoft support, after a couple of failed attempts the Microsoft person offered me to purchase a windows key for a symbolic price.
I did but I have 4 more PCs that don't have activation.
Is there something I can do to get the activation keys back?
-Restore point doesn't work because there isn't one
-The computers were not linked to my Microsoft account.
