XP is not the latest software, it is simply the most popular. Even if the majority of people in the world preferred the original VW Beetle from the 30s (or whenever it started production, I think it was in production for something crazy like 50 years), it doesn't mean that VW are still obliged to find and fix design flaws in it.
Sure, they are not required to. But there are a lot of third party manufacturers that would produce replacement parts, sometimes even better parts than the originals if there was a demand for it. This is simply not an option for Win XP no matter how high the demand is.
This should not be news to anyone making themselves dependent on Microsoft products, but lots of companies are doing it anyway. Guess it would be a bit different if the market was not monopolized.
If a civilization is advanced enough to travel here, they're probably advanced enough to not have any good reason to be hostile.
And we who are the equivalent of amoebas compared to them would know that how?
We can't just assume that advanced civilizations will be nice just because we want it to be like that, there is simply too many unknown factors for us to assume anything. They could just as well have the attitude that there's another little developing planet, blast them quickly before they too invent the Xyz rays and can start to compete with us
I regard Microsoft keyboards and mice as the nicest products they sell.
Then it is almost a little sad that they are rebranded products made by other manufacturers like Logitech or Dell.
For God's sake, stop researching for a while and begin to think!
