It looks like Vista? Are you sure you have build 7000? It doesn't really look that much like Vista to me. Check out the new customisable system tray and the control panel (I couldn't find mouse properties in there even :P). It's similar but not that close.
I agree. It is similar. I never used vista for any real time. My wife has it. Ive had xp 32 for years. The desktop is similar to vista. I have had no problem finding my way around control panel, device manager...all that hasnt changed much.
so far, i still like it. The 64 bit is a nice improvement for me personally. Now i can use all 4G of RAM and 1G of video RAM.
edit: mouse? find it in control panel > ease of access.
