  It's not recommended to change the default file type.

  Hi,

  Like Chilam said, if you associate other files with it, it's invalid. Why did you want that?

  There is no executable file, it's just an DLL fileto be as a shell extension. This type is for certificate file default.

  I want to open PEM (.pem extension) encoded certificates with Crypto shell extensions. Actually PEM files are opened with XCA software and I want to change it.

  Hi,

  It couldn't be opened with Crypto Shell Extension. Even through you associate with this type, it would display error like this:

  

  You could consider to convert it to valid other type file, like .cer. it would be like this:

  This is the real answer here. Works like a charm. FWIW, the icon of the PEM file may not look the same as other cert files (e.g. *.crt) until a reboot, but if you right click the file -> open with -> Confirm/Keep Crypto Shell Extension as associated program and select always open with, Windows will then refresh the icon immediately.
