Hello. In the previous topics, I said that I installed 21H2 LTSC on my new computer, but then it started to use a lot of ram, it uses 8 GB of RAM when idle, it spends 4 GB. And the CPU and disk usage is too much. Therefore, I think I should install 2019 LTSC for less ram consumption and better performance, how is the 2019 LTSC. My system specs are Asus x515EP i5 1135G7 MX330 8 GB RAM 512 GB SSD.

I still run LTSC 2019 (1809) on my X58 system but I wouldn't recommend installing that version anymore. Many newer games and some programs require newer version of Windows 10, usually 1909 or 2004.

21H2 on my main system has a weird commit issue I didnt have in 2019, basically the commit is around double of physical ram usage which is odd, I observed its GPU accelerated software that makes this worse so e.g. if I play a game that uses 10 gig of ram, it will use 20 gig of commit (virtual memory). To compensate I have set a very large page file configuration so I have high commit capacity, the good news is mapping commit to page file actually doesnt cause page file i/o, it just needs to be backed not utilised.

Deffo install 21H2, 2019 is lacking a fair few things, notably the most modern gaming features like variable rate shaders, and directstorage. Also missing things like HAGS and WPA3 support.

I've used 1809 LTSC for a long time and it was flawless. But because of gaming I had to move up, so RN at 21H2 LTSC. The 1809 was a much better overall experience.

I have to completely disable the page file to make it work properly. It's preventing me from shutdown/reboot.

So, if a person was putting it on a server, as a game server, would it matter which one a person used?

I could upgrade to 64/128 gigs but it would be just for the purpose of satisfying committed but not utilised memory. Using a page file to satisfy commit has no performance hit.

Plus I dont think this is normal behaviour, this weird behaviour only happens on my main rig. There is a pool management tool someone talked about on TPU a while back which I bookmarked, whenever I get round to it I plan to diagnose it a bit more.

Ultimately I suspect the solution will be a clean install of windows.

I should have quoted OP, was referring to his problem in my "get more RAM" post.
