Skinning Windows 10 Taskbar

[MeowPurr]

Hi, I'm trying to code a way to skin the Windows 10 taskbar (it's basically the only thing missing now). Right now the only thing I was able to do is use SetWindowCompositionAttribute on the MSTaskListWClass/Shell_TrayWnd to make the taskbar transparent and then place a borderless window under everything and painting the current theme with OpenThemeData and so on, but it's obviously far from an elegant solution.

So I'm trying to hook into explorer and add a subclass so I can add my code to the WM_PAINT event. I was able to get my DLL loaded in explorer.exe but when I add my subclass it hangs because of a new security mechanism in 64 bit Windows 8.1+. Was anyone able to do this without significantly changing security settings?
