I recently tried out the new amazon.com video thing called "Unboxed".
I found that on Vista it does a UAC on *EVERY BOOT* it's starting up a "tray app" / notification thing that asks for the admin rights.
so I sent Amazon an email asking when they would fix this as it should not have to work that way.
I got an email that is just plain wrong.... it will prompt many users to turn off UAC... due to the horribly bad wording they use.
and it makes UAC sound like some kind of evil thing... built to harm the user and make life hard....
here is the text of the email:
"Greetings from the Amazon Unbox Team!
Thank you for your continued interest in Amazon Unbox video downloads.
I am truly sorry for any frustration you have experienced using Amazon Unbox on Windows Vista.
User Account Control (UAC) is a new security mechanism introduced in Windows Vista, whose primary goal is to force users to work using restricted accounts, instead working as administrators. And because Amazon Unbox requires the user to have administrators privileges, Windows Vista users receive an UAC prompt before loading Amazon Unbox.
For further information on UAC please contact Microsoft.
I hope this information is helpful.
Thank you for shopping at Amazon.com."
