purchased a Sony machine preinstalled with XP MCE'05 16/18 months ago and now I want to reformat. How do I acquire the needed software? Being you guys/gals are the best, this is my first place to ask. Do manufacturers usually supply a OS disc with their products? I have heard some do. Just wondering if I got left out or short changed even. Will I have to purchase this software again? I would think not, being I have already purchased it. It should remain available to me the rest of my life (or atleast 75yrs) and I should have the right to maintain it and keep it running smoothly by reformating. Help Where do I start?
