I am not sure, but i think this is one of the wonderful features
Bill gave to us without that we asked for it...

This is an excerpt from a little installer i created with MC.
I think you get the picture...

   put (specialfolderpath("system") & "/" & "KPCPREF/") into dosprefs
   replace "/" with "\" in dosprefs
   ## we can do lots of win-stuff with "get shell..."
   ## but all this has to be in win-format...

   set the hideconsolewindows to true
   ## so we don't see the dos-console,

   ## use "+r" to add it to a fil...

There is an attribute to remove/add a readonly to a complete folder
including subfolders, which i do not have at hand right now. ..
