Rob Nicholson Malt,
Use the Installation Assistant Download Windows 11 to update to 24H2 directly.
Regarding shipping with an earlier version. The devices are manufactured then sit in a warehouse. Just shows when they were build. Or they have been using an older image.
This is nothing unusual. What is strange is why one would update using every version to 24H2 and not just go straight to 24H2.
That's what I did in the end. It was Windows update that went 22H2->22H3->22H4. The download utility went straight to 24H2. Annoyingly, the update program won't run until you also download and run the PC Health Check. Which passes fortunately!
