error in windows txt previewer

Hi
when I click any txt based file: .txt .reg . ini .bat .....
I got a error message in the preview pane in explorer
I am using 64bit windows 7

"this file can't be previewed because of an error in the windows TXT previewer"


and I have checked my regestry, here are some relative key


HKEY_CLASSES_ROOT\CLSID\{1531d583-8375-4d3f-b5fb-d23bbd169f22}

Try opening command prompt (run as admin) and type:
sfc \scannow

This should fix it. If not, try a repair install.
