Upgraded from 10.0 CE to Official
 

It only took about 3mins. I wonder if it's because I had all the updates to installed on the CE. I still don't understand the difference between 10.0 Official and fully patched 10.0 CE.

Same here? Suppose the only diffrence is the Name. or.... more debugged??

This is just a guess, but I'm sure there are several little tweaks that don't make it to patches. You may never even notice them, but I bet they are there. There is simply to many things you do when prepairing software, often you don't keep track of every little change.
