The extraordinary UAC new experience under win7 (1)

        From the XP era to the Vista era and the Windows 7 era, although all of their security policies are different, they all do more or less basic security services in the system. The genuine Win7 operating system uses the "user UAC settings" security mechanism in the Vista operating system, but this function basically guarantees the system security. Let's take a look at UAC and experience the incredible magical effects.

UAC for users, is a very strange term, at first introduce what is UAC? ​​

UAC (UserAccountControl), the Chinese translation for User Account Control, and is a Microsoft WindowsVista The new technology referenced in Windows7, the main function is to automatically trigger UAC when some operations that affect the security of the system, the user can confirm before executing. Because most of the malware, Trojans, and ad plug-ins are like when you enter the computer: copy files to a directory such as Windows or ProgramFiles, install drivers, install ActiveX, etc., and these operations will trigger UAC, users can prompt at UAC It is time to prohibit the running of these programs.

can trigger UAC's operations include:

* Modify WindowsUpdate configuration;

* add or delete user accounts;

* change the user's account type;

* change UAC disposed; mounted

* ActiveX;

* install or uninstall a program;

* install the device driver;

* modify settings and parental controls;

* Add or modify registry;

* ProgramFiles be moved or copied to the Windows directory or file;

* access to other users directory



is annoying UAC, Microsoft WindowsVista start since joined the UAC, which has become one of the VISTA people dissatisfied with criticism, because unlike Vista Win7 UAC as can be Level setting (in fact, Windows 7 UAC is also very annoying), the general configuration of the computer at that time is also very low, so people pop up on this move, but also the guy who locks the screen is very disgusted.

Windows7 of UAC in perfect

because UAC is too much trouble, so Microsoft in Windows7, joined the UAC level set function, corresponding to the four levels:

the highest level:

at senior level, "always notify" (ie, fully open), at that level, the user installs the application, the software upgrade, the application of Caozuoxitong in any case Changes, changes to Windows settings, etc., will pop up a prompt window (and enable the secure desktop), requesting user confirmation. This shows that this level is the safest level, but it is also the most "troublesome" level. It is suitable for multiple users sharing a single computer, restricting other standard users, and prohibiting them from changing system settings at will.
