I read about how to upgrade from 32 bit to 64 bit with clean install. I have a 32bit win7 on my desktop and a 64 bit w8.1 on my laptop.
My question is can I use the w8.1 laptop do download the upgrade assistant and get win8 64 bit? I don't want to screw up my laptop especially cause it has an OEM W8 that I have no idea how to reinstall in case of OS breakdown.
2, In case this is not possible, is there any way to get a 64 bit w8 upgrade downloaded without another 64 bit os already installed?
