lol no job for you

Why didn't I get this?

@GurpreetSK95 That's because after Windows 8 comes Window 10. He was expecting number 10 after 8, not 9 :)

@extery Oh God🙈😅😂😂😂😂
I should have got that

The (uncomfirmed) reason is because of many leagacy programs. They checked the first number in the OS name then it assumes it was win95 or win98.
bool isOldWin = os.version.startsWith(9).

So for the same reason there will probably be no win20 (because of win2000)

@mattiasfestin well, I know a pack of real software that does that

He cpuld havesaved it by saying "Hasta la vista. I'll get some XP for the next Millennium."
