The hard drive is encrypted and you need a bitlocker encryption key to wipe the drive. There is a hidden partition (not so hidden )on the drive that I'm certain has the key stored in it but you need admin user name and password to be able to access. I can run an exploit to accomplish what I need but I'm trying to do it the right way. LOL
You can try to wipe the drive and if successful, you'd need to pay for a new Microsoft license which kind of defeats the purpose of them resetting it. Basically, their reset process was them sending a code to give us admin privileges and the second part is a reset whereby a fresh install of W10 is overwritten to the drive with a license key attached.
My son and I looked at a lot of the coding that was done and boy it's bad. (From a coding perspective) Spelling errors and such.
