Our Help Desk support staff was really perplexed.  They were getting hammered by phone calls whenever a print driver was updated and the Windows 7 clients attempted to upgrade the print driver.  Windows XP clients had no problems upgrading, so obviously there was a UAC issue.

After doing some research a new setting was discovered that by default was set to require elevated permissions to install a new or upgraded print driver.  To allow users to update or install a new driver there are two new gpo settings that need to be configured for your users.

Both reside at the following location:

Computer Configuration / Policies / Administrative Templates / Printers

When installing drivers for a new Connection: “Do not show warning or elevation prompt”

When updating drivers for an existing connection: “Do not show warning or elevation prompt”

By setting both vales as defined above, users will now be able to connect and update their workstations without a Help Desk support visit.
