What is the User Access Control?
Quote In older versions of Windows, if a program such as a virus gained access to your computer, it gained access to everything on your computer. With Vista, your programs (including viruses, should you be so unfortunate as to catch one) run in "unprivileged" mode. This means that any virus you run will perhaps mess up your own files, but not other critical system components. Quote
What is he trying to say .
Also on the subjects of active x and java people are talking about here.There is good active x and java and bad active x and java .It just the programming code the pogrammer use to write the active x and java .They use bad programming code to write the active x and java .There are good pogrammers and there are bad pogrammers .
The OS is not advance enough to know what is good active x and java and what is bad active x and java .Has the OS would have to read the code to see if it is good or bad.
The only thing we can do is send bots to web sites to sniff out bad active x and java.Google does this has I tried to go to a web site and got message from google that the web site may harm my computer.But the technology is just not there for the bots to go to every web site or the OS to read the code and tell you if it is good or has malware.

It’s Microsoft’s attempt to copy the Unix permissions system.
Basically, even an administrator account doesn’t have permission to access the really important files. Instead, they just have permission to temporarily execute commands as a "super user", called Administrator for Windows Vista. In order to do this however, the normal users have to input their password every time something tries to access a file outside of the user’s home directory (usually C:\Users\<username>). This means that when the virus runs, it either has to explicitly ask you for your password (in which case you know something is running because it requires your permission) or the worst thing it can do is delete your Documents folder (it can’t destroy the entire computer).
For the debate between Active X and Java, they are two different things. Active X is an Internet Explorer-only add-on system that gives access to the computer from the web browser. Java is a programming language used to embed software in web pages. It sandboxes the apps so that, unless someone finds a major security hole, it can’t be used for things like installing viruses on your computer.
