Purchased a Sony VAIO from auction recently, (unknown to Sony) but will not let me register, remove or preinstall programmes. Model no. FW21L. System; Visa home premium OMEA. Microsoft serial no. on back of model will not register with Microsoft? Did have an unknown name as admin (in boruch) and no password. Needs recovery disk before use as it does not come with any CD (it is almost new also) Does anyone know what i can do as a way forward??
