A lot of programs (like Agent) can be installed to run from their own directories, without regard for the W7 Program files (x86) nonsense. Data storage directories can also be located outside of 'User' identities, or the inaccessible 'documents and settings' folder, just like on a 'real' computer.
The start menu can be ~ organized by rt/click opening start menu folders, cutting/copying and pasting the links/folders within that window into a recognizable order. Display is ordered alpha numerically, so you might have to number prefix folder names to suit.
Having to run the machine always as an administrator, however, sort of defeats the intention of the account security features.
