Not for how it would be different because aliens are aliens, but because you're presumably looking at something that is the result of thousands of years of iteration and refinement. If you're the Asgard from Stargate, you presumably aren't just doing OS updates and re-skinning your UIs and throwing away your old frameworks every three to five years for the fun of it. At some point you presumably figured out how your software should work, wrote it right, iterated on it until it was essentially bug free, and only extend it as needed within the same set of frameworks, languages and UI paradigms your civilization has been using for hundreds of years.
What does that software look like?
