hi
i sent my computer to service in turkey "koç sistem destek"
they change my mainboard two times in warranty. but they formatted my computer and erased my original Windows. they load different kind of Windows. they erased my original Windows completely i can't recover it. and i cant activate Windows. and i dont have CD.. this Windows is just demo. cant be update or something else.
how can i take my original registered Windows?
can i take original Windows from dell or can i download it?
