How to set 'compatibility' mode permanently?

Vista Home Premium. I installed Winzip 9 because I own and like it. Much
easier than using vistas built in zip functions. I've had to set
compatibility mode to XP and run as Administrator to get vista to actually
write winzips output to the hard disk. So how can I permanently enable
this program to run as 'accepted' without the security dialog blocking it
and wanting permission to continue?

And for ALL the things that are going to be a constant, how can I enable the
actions to be executed without the continual double, triple and quadruple
security and UAC blocking dialogs?
Things like renaming folders, creating new folders, moving files and
folders. Common everyday things I am doing constantly.

It was quite a surprise to discover a few minutes ago that 80 gigabytes of
stuff I installed yesterday...isn't.

Thanks,
McG.
