I have an icon in the notification area entitled "Blocked startup programs".
Clicking on it gives me the options:
Show or remove blocked startup programs
Run blocked program >
View help

the help is informative:

"Run or remove blocked startup programs

User Account Control prevents programs that require permission or an
administrator password from running automatically when Windows starts. If a
program is blocked, you'll see a message in the notification area that says
some startup programs need permission to run. You can run a blocked program,
remove blocked programs from startup, or ignore the notification."

Then it offers this:

"To run a blocked program
Right-click the Blocked startup programs icon in the notification area.

Click Run blocked program, and then click the name of the program you want
to run. If you are prompted for an administrator password or confirmation,
type the password or provide confirmation.

Note
You'll need to repeat these steps each time you want to run the program
after starting Windows."

It's that last bit I don't like!
