One of Vista’s many complaints was the UAC. Just about everytime you make any change you were prompted to enter your password, a miniture hassle. However, in Microsoft’s attempt to appease their quickly defecting customers, they’ve made UAC in Windows 7 less obtrusive as well as changing stuff under the hood. In 7, it is now possible to write a script that completely shuts UAC off. “Awesome” you shout as you jump up and down. Get a tissue because soon after you shut if off, you will begin to cry. Why?
Upon turning UAC off you turn the most secure version of Windows ever into a hacker magnet. Any one can hack into your computer and you would never know. As you can see shutting it off leaves your computer completely vulnerable. There is a solution though provided by Long Zheng of iStartedSomething below:
This is the part where one would usually demand a large sum of money but since I’m feeling generous, there is a simple fix to this problem Microsoft can implement without sacrificing any of the benefits the new UAC model provides, and that is to force a UAC prompt in Secure Desktop mode whenever UAC is changed, regardless of its current state. This is not a fool-proof solution (users can still inadvertently click “yes”) but a simple one I would encourage Microsoft to implement seeing how they’re on a tight deadline to ship this.
The sure fire way to avoid this is set UAC to prompt you “always”. That way you will be notified of changes, regardless if they’re yours or not. It’s better to be safe than sorry people.
