i upgraded to w10 at 32-bit instead of 64. What should I do?

I checked the wrong box. How can I correct it, and does it have to be before deadline?

Thanks so much for your help!!!

As long as you have 32-bit Windows 10 installed and fully activated you are fine. You will have to download the 64-bit ISO file, make a Windows 10 USB flash drive or DVD, boot the computer from that and do a clean re-install of Windows 10 64-bit. You can't change between 32-bit and 64-bit by "upgrading". You have to clean install the opposite architecture.

Thank you. At least now I know. But, machine is fully activated for 10....and I need a cleaned-up system anyway, so I guess I can come in off the ledge now. Appreciate the help.
