Just got this from a computer geek online,a method of updating from lowet version of window 7 to window 7 ultimate. I learnt that window 7 is designed in a way that its already packaged with functions of all versions of it,all u need is to unlock from a lower version to a higher version. And this can be done without necessarily looking for a software but just by a serial key to upgrade which also has the advantage of not making any changes to the files,documents or settings on your system. Contact me on 07067844630 if you want it.

you dont update a lower version of windows to higher one but you rather upgrade it. Update is just for a version connected to internet and receiving the latest security patches and/or service packs without necessarily changing the version name. upgrade is to move from a level to higher version like windows 7 starter to ultimate or vista to windows 7 or windows 7 to windows 8.
so you may not have to make money from this if you do not have microsoft volume license key for windows 7 ultimate version you want to give many responders. unlocking each version in the bundle entails having key for each version to install. to be able to give that key to several people means microsoft volume license key or else people will not have activated windows version after using your ultimate version key and they will blame you hereafter.
