My neighbor's ASUS G74SX is on Windows 10 1909, works fine!

really? please, if you can, tell me if any pieces were replaced? hdd or ssd excepted. I have all original material, except the battery of course. Still use the original hdd, still perfect according to crystaldiskinfo. I use that pc for browsing mainly, fb games, nothing heavy. 1809 version is updated until may 2010, but If I want to try 1903 via windows update, it's now. I am to lazy to create a bootable iso. I am too lazy as well to use Macrium. I have nothing on that computer, it's for testing and see how far that old beast can go with windows 10 *lol* I use right now apple products. Please, don't throw me anything! I'm not a gamer anymore. But I can't throw away a perfectly working computer! And it's too old, nobody would buy it! 😉
So I struggle with, skip 1903 and take 1909 directly, or take 1903 for the next year or so.
MY GOD. Apparently, there are g74 sx to sell for 500$ on the web *kijiji, I'm from Canada* LOL. As I put some $$$ to upgrade a bit, more memory, new battery, I will keep it!
