The Windows Add/Remove Programs system allows for a great deal of information
about an application to be shown in the Add/Remove Programs dialog. Some of
this information corresponds to information provided in a JNLP descriptor, but
JavaWS does not provide this information to Windows, so Add/Remove Programs is
not as useful as it could be for JavaWS applications.

Specifically, Add/Remove Programs entries can contain:
   - Publisher name
   - Publisher email address
   - Publisher's website
   - Installation location on disk
   - Installation date

None of those attributes are present for JavaWS applications in the Add/Remove
Programs dialog, even though they could be extracted easily from the JNLP file
and/or installation process. JavaWS application entrys should also show the
application's icon if one has been specified, instead of using the generic
JavaWS icon.

 - Publisher name corresponds to the <vendor> entry in the JNLP file
 - Publisher email address may correspond to a JNLP entry but I can't
   seem to find which one
 - Publisher website corresponds to the <homepage> entry in the JNLP file
 - Installation location on disk is known by JavaWS. This location is not
   revealed to the user, but Windows uses it to calculate how much disk
   space is being used by the application. Knowing how much disk space a
   JavaWS application uses would be useful, and would make JavaWS applications
   blend in better with other applications.
 - Installation date could be recorded at install time
 - Display icon corresponds to the <icon> entry in the JNLP file

The corresponding Windows Registry values for these under the application's
Uninstall subkey are:

    Publisher
    Contact
    HelpLink
    InstallLocation
    InstallDate (format: "Thu Apr 01 17:30:53 EST 2004")
    DisplayIcon

The control panel button for any given JavaWS entry says "Change/Remove". This
button is mislabelled: clicking "Change/Remove" removes the application
without any chance to "Change" the installation. The button should be renamed
"Remove", which can be done by setting two DWORD values in the application's
Uninstall registry entry:

    NoModify = 1
    NoRepair = 1

Clicking "Change/Remove" on a JavaWS application (in the Control Panel's
"Add/Remove Programs" screen) instantly removes the given application, without
any kind of prompt, warning, or confirmation. Most other uninstallers at least
say "Are you sure you want to uninstall XXXXXXX?" The uninstaller for JavaWS
applications should ask:"Are you sure you want to uninstall <title>?" before
uninstalling.

These additions would make using Java Web Start for desktop applications even
more attractive to developers, since they would have almost the full power of
using a traditional native installer.

Additionally, most of these changes will not require much extra code,
since the information is already in the JNLP file.
