Anonymous8 years ago000Since this is an OEM version, my question is: is the operating system hardware-bound, or can it be reactivated when the mainboard is changed?Show in original language (German)A_B_C_D8 years ago011Wrong ! If you change only one hardware, Microsoft will notice. I had the same problem with Office (original).Show in original language (German)CommentAnonymous8 years ago-101Hello. Whether OEM or retail - the behaviour is the same. If it has been activated once and too many hardware changes are made, the activation expires and must be reactivated. This may only be possible via telephone with Microsoft.....Show in original language (German)Comment
