On another note, since I saw your other thread and I know you're using 1809 for gaming, I would suggest taking a look at 21H2 instead. There's a lot of misinformation about gaming performance on the editions of Windows. Most of it has to do with the timers (TSC, HPET, etc) and a lot of people are getting that stuff wrong, or misleading. The other hugely concerning thing is almost nobody provides any actual benchmarking, I've seen all the videos by guys like Fr33thy, and read all the articles that are copy/pasted everywhere, and after tons of boolean searching on Google with lots of different keywords I can't find good evidence that many of these people have done anything other than just testing it by how it "feels".
There's a really good article and an HPET benchmark program here:
Anandtech recently released an article that pointed out problems with their CPU reviews due to an enabled High Precision Event Timer in Windows. Some Intel processors suffered from decreased performance in games and other benchmarks. Since then a lot of misconceptions are going around. People...

And here's a 90 page thread that has been going on since 2012 to Present:

Most of it boils down to bugs, whether it's bugs in the OS, or bugs in the motherboard, etc. Any tweak that results in "tremendous improvement" is almost guaranteed to be the result of just being a workaround for a bug that the user was experiencing, even if unknowingly.
21H2 has a lot of bug fixes over 1809, and even the "game mode" has been gutted and redone between these two versions for example.
The Spectre and Meltdown fixes are a part of why people are confused about the timer stuff too, alongside changes to the timer frequency reading that people see now "10mhz" vs the old "lower" reading, but that is discussed in more detail in the article above.
Anyway, I myself am first and foremost a gamer, and I'm currently tweaking a 21H2 for gaming. Something you will need to consider as a gamer is that for whatever reason(s) a lot of companies are now forcing users to upgrade from older Windows. Battle.net for example forcibly patched out older windows like XP from playing games that are built for that OS even, and anit-cheat software is starting to force people to move on from 1809 as well. So even if you get 1809 all perfect to your liking, it's possible the game(s) you want to play won't even allow it in the near future, especially now that Microsoft publicly announced it is rolling out 21H2 to Windows Update and will eventually start forcing everyone to update, which means these other gaming companies will start following suit.
