Why not re-install 10240 again and see what happens. Something might have occurred during the upgrade process.

Did the upgrade work properly when you fist started it?? And did you change anything in the registry?? And are you running it on a SSD/HDD or VM??

I was just asking so other might have a clue as to what you did or didn't do to get that issue. Can you expand on how you installed the latest build.. that might help others if not me.

Ok.. and...

What?? Care to expand on that statement a bit. I'm using 10240 and when I started Edge I was not prompted to purchase it. What did you do to get that?? Or what occurred??

+1, I'm in 10240 and when I started Edge I wasn't prompted to purchase it.

If I recall that happened with previous builds as well.
