What is UAC, how close?

　　What is UAC?

UAC, a new technology introduced by Microsoft in Windows Vista to improve system security, requires users to provide permissions or an administrator password before performing actions that might affect the operation of the computer or perform changes that affect settings for other users. By validating these operations before they are started, UAC can help prevent malware and spyware from being installed on your computer or making changes to your computer without permission.

When a permission or password is required to complete a task, UAC warns the user with one of the following messages

1. Windows requires your permission to continue, and may affect the Windows features or programs of other users of this computer that require your permission to start. Check the name of the operation to make sure it is the function or program you want to run.

2, the program requires your permission to continue, not part of the Windows program requires your permission to start. It has a valid digital signature that indicates its name and publisher, which can help ensure that the program is exactly what it declares. Make sure that the program is exactly the program you want to run.

3. A procedure that is not recognized is a program that does not have a valid digital signature of a program that is provided by its issuer to ensure that the program is a program that is not digitally signed. This does not necessarily indicate a danger, as many old legal programs lack signatures. However, you should pay special attention and allow this program to run only if it obtains from a trusted source, such as an original CD or publisher Web site.
