Remotely uninstall unwanted software

Question

Hello All,
I'm currently working on a way to uninstall non-IT approved software from any computer with the SCCM Client installed.  I thought this was simple at first... but am finding a few issues, using a few different methods.
Main problem is that using either Powershell, WMIC or the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall 
It doesn't show every program listed in the "Programs and Features"
For example:  I installed Vuze on my computer to test the Uninstall.  
Powershell script:  Get-WmiObject -class Win32_Product | Where-object { $_.name -match "vuze"}  - Doesn't show it
WMIC scipt:  wmic product get name - Doesn't list it, and just typing in wmic product where name="vuze" call uninstall says "No Instance(s) Available.
and am unable to find it in the proper registry key.
Now, I know what you're thinking, "Why don't you push the software with the msiexec /x {Package | ProductCode}?" 
It would mean I would have to download each and every single program I want to be uninstalled, and keep them in my distribution point (and working at a school, that means a lot of programs to download, and a lot of "junk" software as well)
I'm sure this has been done somewhere else before, and I'm going at it the wrong way.  Any help would be appreciated

Try and avoid using WMI to remove applications.

Windows installer caches a local copy of each MSI on the client machine C:\windows\installer
You do not need to download the application again to remove it from a device.
There are MSI's that don't add themselves to Programs and features.
You might be better limiting who can install software, this will not prevent them from using applications that run from source, I am sure you have come across counter strike portable edition :)
Then there are applications that install to the profile which don't require admin rights.
You will be better spending your time removing admin rights to everyone that doesn't need it then chase up the odd issue afterwards.
Thanks for the reply.  There's nothing I want to do more than to remove admin rights from all our users, but company policy dictates that they all need it... which makes my job very difficult.
