Microsoft is planning to improve the UAC, which stands for user account control, in the next Windows operating system.

“UAC was created with the intention of putting you in control of your system, reducing cost of ownership over time and improving the software ecosystem. What we’ve learned is that we only got part of the way there in Vista and some folks think we accomplished the opposite,” according to a post from Ben Fathi who is the corporate vice president of development for Microsoft’s Windows Core Operating System Division.

According to Network World, in Vista, the UAC can prevent authorized users to access applications on a network although they should have access to it.
