well I actually know neither. I have very slight memories of it. I think I was using windows XP at the time. the game, as I remember, was a bit like those physical fidget games today, in that there was no story (or I didn't understand it yet) or any kind of goals (that I could understand?). there were multiple different locations in the game, one of them us a kitchen similar to this one, but I'm not sure if I could regularly walk across them, or just click on doors or something to move to another location.
given that I couldn't yet read at the time (I think), I have no memories of its title or the desktop icon, or at least I wasn't able to recall it in any degree for a long time.

I expect that back then there were much fewer games released in a given timespan than today, but I don't even know where could I see even a list of them that I could go through.

edit: just checked mobygames, now I see this is a database like I mentioned. I'll check this, thanks!

edit 2: oh well, it requires a registration and a subscription to browse the games database..
