I installed a visual theme for windows 7 a few weeks back and decided to go back to normal. I used uxthempatcher to revert the patched files within the sys32 folder and also reverted manually back the files that came with the theme:

- ExplorerFrame.dll
- shell32.dll
After a restart everything returned to normal except the background of some windows like control panel:

And the personalize menu:

How do I fix this?
