[tex-live] "texdoc <parameter>" cannot be launched from "Start" / "Search all programs and files" dialogue box

[Philip Taylor (RHUoL)]

Over the years I have discovered that many of the commands that I used 
to think needed to be launched from a CMD box or from "Start" / "Run" 
can also be launched from the "Start" / "Search all programs and files" 
dialogue box, but today I found my first counter-example :  "TeXdoc 
<parameter>".  This results in

"Windows can't open this file:

   File: TeXOSQuery.java".

Is this something I can fix myself (by, perhaps, associating the .java 
extension with an image or DLL), or is it something that can only be 
fixed by a TeXdoc re-design ?  There does not appear to be a Java 
executable in .../bin/win32.
