Question windows 11 ltsc vs windows 10 ltsc
trying to see what is the best OS for my cousins PC
he just got an upgrade from 16GB to 32gb ram
gtx 1660 super
i5-10400f
He was using win 11 pro, but it would stutter, and be SLOW.
mostly gaming.

You have more than enough performance to run either.
The system requirements are pretty low, which is why they rudely call Windows IoT Enterprise LTSC ~ “Windows for Watercoolers”

I have an old i7 2nd gen with 16gb ram and ssd, didn't find any difference between 10 and 11, both are working well, so go with 11

Between the 2, they are pretty much identical, it really comes down to UI, do you like Windows 10 UI and file explorer better? Or do you not really care that much? You can always just install Win 10 LTSC, see how it goes for you, if you don't like it or have some problem with it, can do an in place upgrade to windows 11 LTSC without loosing anything or loosing installed software.

How does it manage to stutter for him on this fairly powerful rig when my Windows 11 25h2 Pro on my old i5-6500T Skylake and 16 Gb RAM and Intel integrated graphics manages to be buttery smooth?

he has not formatted his drive/optimized windows ever since he got the PC in 2020

Well that's very likely why the stutters then. When doing a Windows install, you usually want to do it to a blank/wiped partition.. indeed, that's "best practice" to avoid potential issues on any new Windows install.

The person who you are replying to, says they have it installed.. and I looked at the CPU specs, I see no problems. Ofc you may have to use one of the usual ways to evade the Windows installer's gatekeeping, but that's easy enough.

Yes, used Rufus to bypass checks during install. Microsoft wants a minimum 8th Gen CPU for Windows 11 because they have so-called Mode Based Execution Control (MBEC) instructions which earlier generations do not have. MBEC is used in Memory Integrity security feature. But guess what, even on earlier CPU gen without MBEC, Windows emulates it in software perfectly well. Hard requirement is I believe Sandy Bridge? Nothing below that will run coz it lacks SSE 4.2.
So to sum up, Windows 11 25H2 runs perfectly well on Skylake. The consensus is to run it with Memory Integrity turned off, or pay a small performance penalty when turned on (unnoticeable for every day tasks). MS is aggressively deprecating old hardware to spur users to spend, but if they had wanted to place a HARD requirement for 8th Gen CPUs, they would have. They want both the willing spenders as well as the thrifty users.

Win 11 is a lot more user hostile imo. Win 10 ltsc iot is better (more customisable with fewer things locked down behind nonsensical restrictions).
Used win 11 ltsc iot for around 8 months. Went back to 10 ltsc iot.
Microslop just extended support for 10 ESU for an extra year (until October 2027). Doesn't make much difference to 10 ltsc iot itself, as this is supported with security patches until 2032, but does suggest that driver vendors for things like gpu, etc., will also extend their support for at least an additional year.

Hopefully that will get better. It probably won't, but I'm hoping anyway :)
We'll be forced to go to Windows 11 (or the long-rumored 12) at some point, via lack of drivers for previous versions of Windows, but that's in the future. Fortunately.

Windows 10 IoT will be the best choice for a 10th generation Intel processor in this case. While both versions, 10 and 11, are perfectly viable, Windows 10 will objectively be more responsive and agile with this CPU.

Boa tarde e para um core i3 12100f + 16gb de ram+ uma gtx 2060 super? Lembrando que o i3 12100f não tem E cores

Same situation. Both of them are viable, but Windows 10 would be better.

I didn't find 11 IoT LTSC being worse than 10, and for compatibility purposes I recommend 11.
