Windows 10: Lost activation when updating to 10041; need a new key?

The activation key from the previous build now shows as needing activation again.
I tried, and it fails.
Do I need a new key and where can I get it?

:)

 

Windows 10 32 bit to 64 bit

Build 10041 is so old it has expired. You cannot activate it. You need to use 10240 and skip the step that asks for a key

 

Stuck on build 10041

So, A long time ago back on build 10041 I installed tech preview on my laptop. today I came back to this laptop haven't used it since

and I an unable to update from 10041 I am just getting a error(0x8024044a) when updating

no dice.

it says:
That key cant be used to activate this edition of Windows. Please try a different key.

 

What version did you install?
Try the Enterprise Key: PBHCJ-Q2NYD-2PX34-T2TD6-233PK

 

thanks. That was it. Enterprise key.

I have made a new thread but just incase ill leave this here.. So, my girlfriend who went from build 9926 to 10041 is no longer activated. neither of the two product key work.. i have even tried having her attempt to use command prompt for manual activation but nothing works.. Im thinking i could try Microsoft toolkit since it should be activated anyways. Or maybe just wiping it again might work?
