If anyone is exploring options, Windows 10 IoT LTSC has official support till 2032. Added benefit is that it doesnt come with preloaded bloatware from MS.
I have recently installed W11 IoT LTSC on a 3rd gen Intel, the TPM requirement in this version is optional.
The problem with LTSC is that it is very hard/impossible to get it legally as an individual. You can do it in unofficial way but that has its own problems.
It's not that hard. Give CDW a call. You'll need to setup a volume licensing agreement, which means buying at least 5 licenses, but there's some $10 licenses you won't use if you need filler. Also, this is an upgrade license, you need an underlying windows license on each PC to upgrade it.
That is a different product. LSTC != IoT LSTC, it is so confusing. To get the IoT you have to sign lots of contracts, Microsoft sends you stickers to put on each stuff, stuff like that.
When is the release date for Windows 11 Enterprise LTSC?
It will be officially released in 2nd half of 2024, more info. Download links will
be shared here. Insider build ISO for Windows 11 LTSC has been leaked but we
recommend not installing it for general use because its authenticity can not be
verified.
Update - 24-May-2024
Windows 11 IoT Enterprise LTSC 24H2 is released to OEMs. We got the official links
from OEM portal, and it's added [here].
You can probably download it if you have a Visual Studio Professional or Enterprise subscription. VS Professional costs about $1,100 for the first year, and about $750/year after that. You get access to all MS software BUT you can only use it to develop software. You cannot use it in production.
I do have the Enterprise subscription, which is how I know that this product wasn't launched yet. There is a "Windows 11 IoT Enterprise, Version 23H2" and the usual "Windows 11 business/consumer editions, version 23H2", but nothing with LTSC.
As one of the other comments mentioned W11 IoT LTSC was released quite recently, 24H2 I belive. It is a legit general availability release obtained from the same website.
