Hi Tom,

I would leave UAC enabled.  Yes, it can be a pain at setup, but User
Account Control can help prevent unauthorized changes to your computer
by prompting you for permission to perform tasks.  You can read more
here to:

'Search Results'
(http://windowshelp.microsoft.com/windows/en-us/search.aspx?=&qu=UAC)

You can still do everything that you use to do in XP, but now you have
to give the program permision when it tries to run with Administrator
privileges first before it will be allowed to run.  Vista also will not
let you modify system files without taking ownership of them first.
This helps prevents a accident with them.  You can see about taking
ownership here.

The safest way to run your system would be to create a "Standard" user
account and run in it, and only use the "default" Administrator account
when you are doing a lot of installing or making system changes.  Make
sure both accounts are password protected.  As a Standard user, you
would have to enter the Administrator's password to give UAC permission
to a program.  If a program tried to take control of your computer, it
would not get far at all in a Standard account.

Hope this helps,
Shawn
