Application Icons

Solidworks parts(.SLDPRT) and Drawings(.SLDDRW) have the same icons in windows explorer  while assemblies(.SLDASM) icon is unrecognized.

I don't know since when this has happened.

Is there any way to correct the icons?

I'm using Solidworks 2013 on a windows 8 x64 bit machine.

Any kind of help is much appreciated.
