Part 1 – Microsoft full version products. xxxxx – OEM – xxxxxxx – xxxxx
First set, 5 digits. Must be a julian date. (ex. 132nd day of 1996 would be 13296) This will work with all dates in the year equal to when the product came out.
Second set, OEM nothing to do here
Third set, 7 digits. Add up all 7 digits, they must be equal to a multiple of 7.
7, 14, 21, 28……. etc… (ex. 0035141 : 0 + 0 + 3 + 5 + 1 + 4 + 1 = 14) As long at the number is divisible by 7 with no remainder, you are ok.
Fourth set, 5 digits. Anything you want,.. birthday, lucky numbers, locker combo… etc..
Thats all there is to it.
Part 2 – Microsoft upgrade products xxxx – xxxxxxx
You need the origional version on your system in order to install the upgrade, however the upgrade is cheaper to buy…….
use the complex math formula to crack your upgrade version and make it become the full version,.. take the upgrade number you have on the back of the CD case..
(ex. 8113 – 2612415) subtract 1 from the first number…
8113 – 1 = 8112
use that number with the existing second number, and the software will no longer look for a qualifying previous version and will install in full.
