UAC:Lets Try That Again
Windows Xp's reputation for shaky security stemmed in part from scary possibility of hackers worming their way into your PC and launching applications or changing settings at will.
In vista,Microsoft responded with User Account Control,a safeguard that tries to protect you by asking,in effect ,"Are you sure?" before executing a wide variety of system actions.The problem is that ,in the vast majority of instances,those actions are intentionally initialted by user.Telling Vista that you know what you are doing gets old quickly.But vista's UAC essentially has only two settings:on & off.
Windows 7 still lets you opt for full-tilt UAC or no Uac at all.It adds two usefull intermediate settings, though:One notifies you to attempt to install software or change settings without making you click to continue,and the other notifies you only when a program tries to change settings.Both of those options alert you when potenially dangerous actions transpire on your PC ,but your work wont grind to a halt nearly as often as it does with vista's version of UAC.
The UAC settings reside in a new control Panel section called Windows solution Center,which replaces Vista's Security Centre.It's home to features for adjusting security settings,using Windows update,and backing updata.the Solution lets you turn off various windows notification,such as those warn about security settings.Turn off every nagging notice that windows 7 lets you disable,and you could windup with least instrusive edition of os in a long time.
Did we say that windows 7 is longer on substance than style?For the most part ,that's true.But the new features for applyings themes to windows interface are nicely done.As before,the theme controls lets you choose collection of wallpaper,color schemes,sounds,and screen savers to give windows an instant makeover.
In windows 7,however,you can see a full-screen preview of a theme's effect on the OS with one click,and its's easier to create and save your own themes than it is with Vista's antediluvian controls.
