I wanted to do some User Permissions testing using Dynamics AX Client with different users using Run As Option. i.e. Right-Clicking the client and then bringing up the Windows challenge dialog wherein one can put the user name and password shown below
In previous versions of Windows, when you right-click it will bring up the Run as and you can put the user name and password, but with Windows 7, When you Right-Click it just shows "Run as Administrator"
If you need to "Run as different user" then you need to hold the SHIFT button and then Right-Click AX Client.
