Microsoft stops giving updates to end of life products. Unless it’s LTSC 21H2, you might want to consider installing the regular release of Windows. The LTS version doesn’t allow you to migrate away from it, so it won’t upgrade. You have to reinstall Windows.
It is 21H2. Plus I have no reason to ever upgrade. Windows 10 is better than Windows 11 IMHO. The specific reason I use LTSC is because it doesn’t come with all the bloat that a normal install comes with.
LTS version is hardened and more secure by default. But that also makes it a pain in the ass.
If you ever do get around to upgrading and don’t want the bloat, the N version is what you want. It’s the European version and doesn’t have any extras.
