Secure-It drop.exe Context menu

I activated the context menu for a hardening program called "Secure-It", which allows me to run a program with lesser previleges than usual for security reasons.

When I right click on an icon, I am present with 3 options/items (See attachment):
*Run as Normal user - Non Admin
*Run as Contained user
*Run as untrusted user

I am using a Limited account on Windows XP

Which of these options will run with the least previleges and which with the most?

 

I believe it goes in descending order. Normal User being the least restricted, Untrusted being the most restricted. Normal is suitable for just about anything, the others will probably break most things. For more info look here, which is where it came from.

 

I just read the Microsoft MSDN website. And I have came to the conclusion that if I am already running with a limited Windows XP account (non-admin) then I do not need the secure-it drop.exe as it does nothing further then what running with an limted account does.

Drop.exe or DropMyRights.msi > Admin, if else
Limited > Not required
