I downloaded the new Windows 10 preview and took a peak. The file copy and task manger are still there. The start menu feels nice. It it a little different then the windows 7 menu. There is a mini version of metro (looks more like a windows phone screen) on the start menu. I didn’t play with it too much but I didn’t mind it there. The apps behave like normal programs rather then gobbling up the whole screen. You can re-size them and and minimize them. So far I am pretty happy with what I am seeing. The install still prompts you for a Microsoft account and to download and install apps you still need to be signed in. Not my favorite thing but I guess it is true of all the app based software.
I will update after I have looked at it and installed some more software.
