When clicking on "Advanced system settings", I need to login as the administrator and hence only edit the administrators environment variables (in addition to the machine wide ones). How do I edit the environment variables of a standard user?

Details

With the migration to Windows 7, I decided to work as a standard user instead of an unprivileged administrator. Works well so far but I encountered a tiny problem:

When I try to change per user environment variables via the control panel I have to login as an administrator. But since I run that part of the control panel as the administrator I can only edit the administrators variables.

How am I supposed to edit my own environment variables? Without resorting to extreme measures, such as editing the registry (as suggested in "Is there any command line tool that can be used to edit environment variables in Windows?" )
