I cannot just remove the permision to install software from the local
administrator or the domain administrator accounts...

Normal users cannot install software, but local/domain administrators can and
should be able to do so at any time (except for software that can be installed
with WPKG).

Ok, let me show you what WPKG is actually doing:

Since the log files are so long I've posted them here:
http://pastebin.org/34676
(If I missed an important case just tell me what you want me to test and I''l
provide the log)

See the 6th and 7th case where Firefox is not in the profile but installed on
the machine and WPKG removes it when the /force parameter _IS_ used but not
when /force _IS NOT_ used

I want to have a way where WPKG removes any installed software which is in
packages.xml but not in the local wpkg.xml.

Yes.

Well, obviously (7th case) WPKG does remove packages from the system when using
/force.

This is where you are wrong.
I'm not talking about "any software on this planet" but about "software
specified in packages.xml" here! Firefox _IS_ in packages.xmlm WPKG _DOES_ know
how to uninstall it and /force does exactly that.

> Even your request does not change this fact.
Maybe I didn't manage to explain well enough what I want. I want a mode that
re-evaluates every package's state on the machine. A mode that does exactly the
same as /force at the beginning but that does not execute the <install...>
command but the command appropriate for the current state of the package:

- If the package is not installed on the machine and not in the profile
--> Do nothing

- If the package is not installed on the machine but in the profile
--> Install it

- If the package is installed on the machine but not in the profile
--> Remove it

- If the package is installed on the machine, in the profile and in the local
wpkg.xml
--> Compare version and either update or leave it as it is

- If the package is installed on the machine, in the profile but not in the
local wpkg.xml
--> Compare version of installed package and either update or leave it as it is


I hope I managed to make it a little clearer as to what i want. ;)
