I'm currently running Win7 and due to issues I'm having with Update and Backup I'm convinced I'm having registry issues that I don't want to/am unable to deal with--without getting into the specifics of those, suffice it to say at this point it seems much easier to simply re-install Win7 and start fresh. I have all my files already backed up on an external drive and have the original Win7 install disk.
My question is: going from Win7 to Win7, if I use the Upgrade install option (as opposed to Custom), will this really give me a clean re-install, i.e., create a fresh registry (and presumably resolve the system issues I've been having)?
Simply asking because as I understand it, Upgrade will retain all your programs and files, whereas with Custom I'd have to re-install all my programs, which I'd like to avoid if at all possible. Just want to confirm that Upgrade will give me a truly fresh system install.
