Changing 32bit to 64bit Windows 7 using a Win7 installer from torrents

you will need a win7 64-bit installation version and a Genuine Product Key that match the 64-bit version.

a 32-bit version product key will not work with a 64-bit OS version

32-bit version product key will not work with a 64-bit OS version < keys are not bit specific 32 bit key will work on 64 bit install

Can i use a Win7 installers that i got from torrent sites < many contain added viruses and malware

so....
*i can do use my OLD product key to reinstall win7
(even if its 32-bit.)
*using win7 installers from torrents are risky

then..
is it possible for me to obtain a free copy of an Original Win7 Installer.(without the product key of course.) and use my old p.key to activate it?

+1 to the link MyNewPCBuild provided. Just get the official MS ISO and install away!
