Half my software won’t even work on Win10 anymore (older versions will), and a lot of the code i’m developing requires newer APIs and features (and services!) not in LTSC builds.

​

If you’re using the LTSC IOT version, that’s binary identical to mainline IOT. Expect things like adobe applications to stop working, and for a while the win10 versions of various games required newer releases than LTSC Was… and now some are W11 only. Staying on LTSC is a fool’s game in the end, while things might work “right now” … I can’t even install my headset or keyboard control software on LTSC. Running LTSC is like running embedded as your main system… because that’s what it’s designed/tooled for. Don’t even think of newer MS office support, etc…

​

If you’re using normal IOT Enterprise, then everything will “just work” since it’s identical to normal windows 10 enterprise.

Perhaps I’d sooner do that than reinstall W10, but I’m very, VERY much not a fan of opening myself up to that god-awful piece of spyware.

F100 government contractor here, working high up on the systems mangement/deployment side. It’s *no* different than 10 in which data is transmitted, and that’s publicly documented. Our infosec teams went and reversed/intercepted a lot too to verify this.

​

W11 is a great technical upgrade under the hood. And the “spyware” is the same as W10 and W7’s telemetry (admittingly, W7’s was added later).

​

That being said, on the personal side, from a game/stability perspective, i’ve seen some higher framerates - it even made one game (tom clancy ghost recon wildlands) playable on my system at 4K HDR while under W10 it wasn’t. I went to 11 on the first insider builds and was extremely happy with that. Sure, the start menu changes, but … especially on the latest versions, all the early 11 complaints are gone.

​

But light on resources and privilege? Even on 2GB ram machines i’ve noticed no difference from 10. Mind you - 2017+ machines.

​

Just run 11 with ‘security only’ or ‘basic’ telemetry set via local GPO.

​

Don’t run ‘debloating’ scripts - these really can and do break things, even if you don’t see it for a year or two. Right click and uninstall things you don’t want. Read the technet documentation (well, learn.microsoft.com now) to properly tweak/manage things using the already provided interfaces instead of 3rd party hacks

And will potentially give you app compatibility hell.

​

I’ve had to move so many organizations off through reimage projects because they thought that and applications dropped support for previous releases because of using newer services/APIs.

​

Nevermind games.

​

LTSC is the replacement for emebdded/Industry pro. And tooled as such.

​

At this point i’d reinstall with W11 for game and hardware support (and security), but the current ‘regular’ Win10 build is essentially LTSC … it’s the last feature update, and past few years it hasn’t had a core OS update.
