Musicclover,

EaseUS partition software was error proof for me and I did it without reading lots of directions first. It allowed me to keep all my data on my C and D partitions. It just shrunk D drive by the amount I wanted and then added it to the C partition.

I don't know whether it allows you to transfer data from one to the other. I think not.

I do love Windows 8. It has a better way of saving power by giving me a "sleep" option instead of shutting down so often. It recommends using that and keeping the computer on all the time. It certainly is easier to navigate around different programs. I found Windows 7 to be difficult in locating programs and files. Win8 is easier with it "Search" area allowing you to add tiles to the start screen.
