LTSC is enterprise Windows. It's not for gaming. And no one can have it legally on a home PC. It's impossible to buy it as a private person.

I think you could get it via MSDN subscription as a private person, though it would cost way more than a single traditional Windows 10 Pro or Home license this way.

From what I understand Battlefield 5 uses and has working DLSS1.0 Support under 1607 LTSC, which is supported at Windows kernel/driver level. Cyberpunk users DLSS2.0 which needs a later windows build to function.

So if you are happy to play with reduced performance and not get access to the better functionality offered by newer Windows builds there is nothing to stop you playing Cyberpunk 2077 without DLSS.

Back then may be. Though MSDN no longer exist. But 99,(9)% of LTSC users here have the warez version. Yet i can understand developing countries, where home version cost more than monthly income, but United Kingdom above ^^^

My dude, I don't mean to be rude, but just update your Windows. It's not that hard, and it's just fine. I used to be running 1505, and now am on 20H2. If you can't use Windows Update, download Windows 10 Update Assistant, it's on the Microsoft support site and it's literally free. Might take an hour, but it's 100% worth it.

Peace and love, dude. take care

for those who find the step to LTSC a bit much here is a perfect other solution.

I'll have to disagree with you.
Maybe if you use the system JUST for gaming - sure, this is the easiest solution. But if you have tons of software that changes the system in one way or another - this may be much more trouble than it's worth.
For example, I make music as a hobby, with tons of VSTs installed, and an unofficial audio driver (not ASIO, btw), and updating/reinstalling Windows completely messed up my sound quality, and I was unable to fix it. Maybe if I spent several days trying to pinpoint the issue - I cound have made it work, but instead I had to revert the Windows. First time - through simple rollback, and the second time - through the whole drive image, which I'm really glad I was paranoid enough to make, because I was really close to losing my mind when the first rollback failed.

I know that my situation is a bit specific, but you have to understand that most people that decided to stick to 1607 have their own valid reasons to do so.
So yeah. Sometimes updating is just not worth the trouble, and that's why I'll rather NOT play the game, and stick to the older Winows without any feature updates.
The only way I'm ever going to update - when I'll get another SSD, to install the new Windows as a secondary OS, and then play around with it without praying to every deity that my backup successfully reverts the system back to working state.
