It may make more sense if you know that WPKG keeps a record on the client
machine of what software it has installed. That file is at
%windir%\system32\wpkg.xml. When wpkg.js runs on the machine, it reads
hosts.xml, profiles.xml, and packages.xml (or their included directories) and
determines what packages and versions should be installed. If a package logged
in the local system32\wpkg.xml is installed but is no longer specified for that
host based on the server-side xml files, then wpkg.js runs the remove commands
for that package. There is not an explicit directive anywhere to "remove
package x", nor is it necessary in normal circumstances.
If you were to run wpkg.js on a machine, then delete system32\wpkg.xml and
change the server-side xml files so that the package no longer applies to that
machine, and then run wpkg.js again, it would not remove the software. In
effect, WPKG would be unaware that the package is something it had installed
and falls within its scope of management.
If you need WPKG to uninstall software that it never installed originally, you
can create a package for that in a sort of reverse way. Make checks that
evaluate to true if the software is NOT present on the machine, and use the
package's install commands to call your uninstaller routines.

Hi John,
thank you very much.
I understand your answer in the following way:
Eachs package that exists and is not assigned to a profile will get uninstalled
on all clients, that are assigned to this profile.
Is that right?
Greetings
Alexander Ninnig

Remove the package line from the profile in profiles.xml.
