Windows 10 32 bit to 64 bit

I had a Windows 10 Pro 32 bit OS which was activated. Now, I have installed a clean version of 64 bit Windows 10 Pro Technical Preview Evaluation copy Build 10041. But I am unable to activate it. It asks for a product key which I dont have. Please suggest.

 

Windows 10 Pro 64-Bit to 32-Bit?

Hi,


Thank you for posting your query in Microsoft Community.



I understand your concern and will assist you to resolve this issue.

  What is the name of the game?
  

If the system architect is 32 bit, then you can’t install 64 bit version of windows in it. I suggest you to run “winver” by pressing Windows + R, and check the version and bit.

There are some games that you can install it in 32 bit as well.

Windows 10 is the free upgrade for those users who has genuine key for Windows 7 and Windows 8.1 , normally it doesn't require activation, it's gets activated automatically, in case if you face an issue with activation the you can get back to
us.



For reference you can refer the link below and check if it helps (32 bit and 64 bit architect applies same to windows 10)

Windows 10 Activation If shifted from 32-bit to 64-bit

I have Upgraded from Windows 7 Pro To Windows 10 pro and Linked the Windows 10 Product key to my Microsoft account.

I wanted to use 64-bit so if i install 64-bit on erasing 32-bit, will i get windows 10 64-bit activated by signing in with my Microsoft account?
