Re: Default program to open folders and media?!
The little silver zipper icon is the windows default decompressor, it opens compressed files such as .zip, .rar etc
A System Restore may be able to get your associations repaired.
I don't know what the Microsoft .exe is called, someone else may be able to provide that info, if they can then just use the method freestyler posted and navigate to the location of the .exe
Alternatively just use WinRAR or Winzip
