So I am readying my 3.06ghz C2D MSI lappy for sale and I took out my SSD and put a 7200hdd back in. Downloaded an ISO from Digital River.. 64 bit. Used the Microsoft Install Tool and put it on a thumb drive. Installed .. blah blah blah.. During the install I was asked for the key.. I turned the lappy upside down but could not distiguish if 2 digits were 0's or Q's.. so i skipped ahead. After completing the install I thought.. "Why don't I just install Magic Jellybean Keyfinder" to find out whether the digits were 0's or Q's.. I wasn't sure if I could find a magnifying glass in the house.. or even if a magnifying glass would be able to distiguish the digit correctly anyway. So that's what I did... Boom ! THE KEYS ARE COMPLETELY DIFFERENT !! I am very disheartened by this.. The MSI came with Windows 7 from the factory.. The Digital River ISO is likely a Retail image while the comp came with OEM Win 7... this used to not really be an issue. There is no advantage to a Retail ISO other than it being void of the factory Bloatware..which I would have removed from an OEM disc install anyway. What is going on here? I have no interest in getting into an incorrect key situation with Microsoft.. I need my copy of Win7 validated quickly so I can put the MSI for sale quickly.. my new lappy has already arrived. I need some help/guidance here.
