I turned on "Make Start, taskbar, and action center transparent", but it does nothing. It still appears as a black bar and the wallpaper below cannot be seen.

"Also, you are using TH2 (10586), latest stable build is RS1 (14393)." How do I switch this?
I installed the theme you told me (installing the uxstyle thing before hand). It does nothing either. The theme doesn't show up in the Themes list.
Edit: I did manage to install the aero themes you suggested, but whichever I select, it looks like crap, and nothing at all like Windows 7. The taskbar is Windows 10-style intact, and according to the theme screenshots on deviantart, it should look exactly like Windows 7 itself. I did install the themes for 10586 version.
Also: Every time I load a new session a popup with Aero Glass Information (serial number etc.) appears. This is also annoying. Can this be disabled?
