Well, I tried. I promise, I honestly tried, when I re-installed Windows a few month ago.

But since a few weeks I switched my limited account to an admin account again.

It's not so much the application, which will not run on a account with restricted access (you can use "run as" or give such an application additional rights), but it is two issues that really annoyed me:

* You cannot run the explorer using "run as". Anybody managed to do that?

* You cannot use fast user switching when the welcome login screen is disabled.
