Vista - Adminstrator rights question

hi,

i upgraded to vista premium home edition a few weeks ago. i am the only
person who uses the computer, and when i click Control Panel > Users it says
"administrator" next to my name.

However, one quite a few occasions when changing settings in Vista, or
sometimes changing settings in programs like SpyBot S&D, i get an error
message that says I need Admin rights, and so i should log back on as
Adminstrator.

In the case of SpyBot, I just ignored it and I was allowed to change the
settings. I can't remember what happened when I tried to change some Vista
settings, but is there anything I can do to stop these incorrect messages
from occurring?

so thats my 1st question.

the 2nd is, whats the purpose of "system.old" folder? I imagine it would be
handy if I want to roll back to previous OS, but is there any other purpose?

thankyou

Hello,

Even a user account designated as administrator, is not the true administrator account. There will still be prompts for programs to run, etc. This is by design, the UAC (user account control). It keeps your computer safe from malicious code.

If you really want to use the built in (but hidden) administrator account, this tutorial will show you how. It also has links to related topics on the UAC and administrator accounts: Administrator Account

I hope this is helpful.
