As David said, the UAC prompts can be turned off in the Control Panel. I'd
recommend against doing this for security reasons however.
People need to stop saying UAC provides "security". It doesn't really.
Source: You may be surprised: Microsoft themselves.
Microsoft has admitted that yes, UAC is liable to social engineering.

The design shold have been more along the lines what they do with
their browser where YOU the actual owner of the computer decide on the
level of secuity you want to have. This either nothing (turned off) or
endless nag screens when on and often difficulity changing permissions
has got to be the biggest marketing blunder Microsoft ever dumped on
their users.
UAC is simply far too intrusive and not ready for prime time. The beta
testers screamed bloody murder about it during beta testing and
Microsoft cut it way back in how intrusive it was, not nearly enough
obviously. Of course the point is if you cut it back too much then it
becomes worthless. Either way it far from bullet proof as I've been
saying.
