Opinion: Downloadus interruptus
Bzzt! Bzzzzt! We’re sorry, we have to interrupt your download of Windows XP SP3 and Windows Vista SP1 because they interfere with some silly accounting software over which Microsoft has no control. Those third party programmers, and we use the term loosely, are so inept. Bzzzzt! Bzzzt! OK, you can download again now we’ve crossed them off the list of acceptable recipients.
