Ultimate Boot CD is completely free for the download, or could be obtained for a small fee. If you had somehow paid a ridiculous amount of money for it, you have most likely been fleeced. The least you could do is to make as many copies of the offical UBCD and pass it to your friends, relatives, colleagues or even complete strangers to minimize the per unit cost of your loss!

Windows 10 laptop has user's pin lock.

Windows 10 pin password lock is associated with user/owner's Microsoft LiveID (Owner's email account and password).

If the mainboard is replaced, then the original PIN will not working. Because it has encryption and need to match the key value in the original mainboard's bios. 

If you try to reset the pin, Windows will ask owner's LiveID/email password.

If you want to do a full hardware test, contact customer to see if it is ok to wipe the HDD and OS reinstall (KB & Driver Update).

Or do MRI and send back the unit with HDD's original state.
