Thanks, I had to call Microsoft to confirm. As you wrote, only the VDA license is needed, not Windows 7. I guess Windows 7 comes with it.

When doing VDI, you don't have to license the Windows that is installed in the virtual desktops. Instead, you license the device the user is connecting from. If users were connecting from a PC and the PC is covered under Software Assurance then there's no additional licensing needed for VDI. For non-SA devices (including thin clients), you will need a VDA license on each one. It's a yearly subscription license.

Besides the Windows 7 licenses, would I need a VECD or VDA license? What's the difference? Thanks, _______________________________ Hector Minero NSWCDD K55 Ph:(540)653-8859
