A few animations and shortcuts not working

[Caspid]

A few shortcuts, such as Win+Home, don't work.
In addition, a few animations aren't being displayed - a program being launched from the taskbar, the taskbar mouseover "glow" that follows the cursor, and the taskbar window preview fade-in effect. Others, such as opening/closing windows, windows being minimized, and Win+Tab still display.

* All items are checked in SystemPropertiesPerformance - Visual Effects.
* I've done some theme editing, but the problem still persists after switching to the default Windows 7 Aero theme (or any other).
* Latest graphics card drivers are installed.

I have no clue what the problem is. Any help would be greatly appreciated.

So I restored all the files I'd changed:

C:\Windows\Branding\Basebrd\basebrd.dll
C:\Windows\explorer.exe
C:\Windows\System32\taskmgr.exe
C:\Windows\SysWOW64\authui.dll
C:\Windows\SysWOW64\shellstyle.dll

// Universal Theme Patcher
C:\Windows\System32\themeservice.dll
C:\Windows\System32\themeui.dll
C:\Windows\System32\uxtheme.dll
​

but still have no luck in getting the visual effects and shortcuts to work. This makes me think that perhaps my build of Windows doesn't have them... Can anyone else verify? Any other ideas?
