I had a 32 bits windows 7 ultimate installed on my laptop though my processor is 64 bits. After installing windows 8 my system information is showing "System type : 32-bits Operating System, x64 based processor." I am sure I have installed windows 32 bit. Strange while installing or downloading ISO there was no options asked to select for 32bit or 64bit.
Could someone help for me to get 64bit installed instead 32bit. I think the KEY would be valid for 64 bit too.
