Just to update my own question, I'd like the group to know that I found a solution by software and what a great piece of code that is.
I discovered it by accident, installed and liked it so much that I asked the developer if he could implement the option to switch users desktops. Which he kindly did. The author is Kay Bruns and his program name is SuRun: http://kay-bruns.de/wp/software/surun/ the page is in German but there's a link to translate it to English. So, what is SuRun? It's a program to facilitate users life running as non-admins, which was a headache to some people, because software developers didn't took in consideration the LUA principles advised by Microsoft, which in turn the latter also didn't follow their own principles. Examples of this, is the date and time control panel applet doesn't run under LUA, Power Options settings not allowed, etc.. Games and other software that require admin rights, you name it. Also, when using a LUA, any modifications you want to make, you make them by running "runas.exe" which it's not practical since it runs in the admin context and not in the user own context. SuRun comes to the rescue solving all those issues, you are granted permission to run time and date, Powercfg, etc.. you can run any application with elevated privileges under your own context, you can store passwords to start an application as admin and never be asked again for it. passwords are entered in a separate desktop, defeating the purpose of keyloggers and the like to steal your credentials. There's more options that you can read in the site and check for details on how it does it's thing. SuRun is opensource, so you can deploy it in your work environment too. Works in XP/Server 2003/Vista and Kay is trying to fix compatibility issues with Win7. He's a great person, always listening to users and implementing new ideas. There's also an English forum located here: http://forum.kay-bruns.de/forum/8 Take a look at it and report back if you find it useful because it surely is for me. I'm running a LUA for some time now and I only find it comfortable with PowerPro, which I have set many commands to make things easier. Sorry for the long post. Hope it helps anyone.
