Hi! I am currently trying to run EE2 on Windows 8, 1080p but the game goes into the taskbar after I open it.
I've tried to run it as an admin, to kill explorer.exe and set compability mode to Windows XP, still no luck.

I'd like to know if there is a fix to this issue, apart from the unofficial patch I've found on the internet
Thanks!

Why not unofficial patch? :)

You can try just Windows 8 FIX:

But I still think UP1.5 is better (doesn't kill explorer.exe), and also supports your screen resolution 1920x1080:
