For many of the new Vista users the User Access Control (UAC) is probably the most annoying piece of software bundled in the Operating system.
There are many ways to get rid of the UAC alerts but not all are geeks and not all would be able to follow the instructions properly.
NoUAC (French language site) is a utility which will make your life much easier with regards do disabling the UAC completely.
NoUAC works out of the box and does not require any installation, simply download the file and double click on it.
Make a selection to either disable or enable the UAC based on your preferences and click Ok. Your preferences will be automatically applied to the system.
Note: You will have to restart your PC once for your UAC changes to be applied to the PC.
On final thoughts thank god for such developers who make life much easier for people.
