Win7 32bit upgrade to 64bit on a new PC
Bought a used HP EliteDesk 800 G1 PC. It's a Quad Core i5 with 4 Gb of RAM. It presently has Win 7 32 bit. I was told it originally came from HP with Win 8. Not sure what version. It did not have a COA sticker and the seller (CS student) gave me one he had lying around since I complained. I have other Win 8/10 machines so I know they don't come with a COA.
Couple of questions since I want to upgrade to Win 7 64 bit. Using a key checker I see a Win 7 key (not the one he gave me) and the UEFI "key". Is the UEFI "key" useful for anything? Should I try to use the Win 7 key that the key checker found or the one on the COA he gave me?
I have loaded Win 7 many times to repair or upgrade a PC and have all the versions. I have not installed Win 7 on a machine with UEFI so I want to be careful before I start. I have no problem wiping the data on the disk if that eases the install.
