No, I really need to do a clean install. I've had a issue in my current install of Windows 8.1 Pro w/Media Center x64 since the summer, when I lost my old internet connection. After I got my current internet service in my name, the settings menu doesn't open. I figure the clean install, which I put off doing, as I knew I was getting a bigger ssd down the road, would fix that issue. I know how to use shift/restart to get into it, but I'd rather just do the clean install of everything on the new bigger sd. I already deauthorized and uninstalled my Origin & Steam games and the games folder I made in C:\Program Files (x86) pointing to my 120GB. OCZ Vertex.All, I really have left to do before the clean install, is to download the current version of Steam. Everything else, I have the updated installer's for, including my driver's.Then after I have W 8.1 Pro w/Media Center, my games, drivers, programs on the new Intel ssd, I'm gonna let Samsung Magician erase everything on my 840 Pro 256GB. ssd, before installing Windows 10 TP on it. I'm not really going to install that much in Windows 10. I'm more interested in just getting used to the changes in 10 compared to 8.1. I'm probably going to put one of my old WD Cavai Black 1.0TB's back in for 10's personal files. I'm not installing all my desktop software in 10, though. I'm only going to try a few of them in 10 for now.
