To cut down on malicious software applications and beginner computer users from changing critical computer settings, Microsoft has included a new feature called User Account Control, primarily known as UAC. UAC is a great step in the right direction. It can be used to prevent a beginner computer user from making changes to their computer by restricting them from accessing or even saving any changes to critical areas. UAC is also helpful against Spyware and other malicious software because it will require the user to consent to the action, before any system changes are made.
UAC is a good feature but sometimes it is necessary to tweak it a little so that it is less annoying for more experienced users. For example, an advanced user may be overwhelmed by the number of pop up authorization they receive. By tweaking the settings they can reduce the number of those they see as well as completely disable UAC. Although I do not recommend you completely disable UAC, you can fine tune it to be easier to get along with.
