Re: [Trisquel-users] Does windows 10 put data on your mainboard?

I don't think it's anything that was added by Windows. The BIOS string is  
there because the manufacturer (OEM) added it there. All BIOS flash ROMs from  
the OEM are likely to add that string back if it was there in the first  
place. You'd need a completely free BIOS ROM (LibreBoot).

Retail Windows installations do not use the string in the BIOS. They send a  
hashed ID made from the motherboad serial numbers. They are unique to each  
machine and they are stored not on the computer but on MS activation servers.
