Microsoft has the User Account Interface (UAC) as one of the most significant new security features. The UAC used by Microsoft is a security model that has been used for a long time in Linux and Unix-based Mac OS X. It requires users to operate some tasks such as installing software, but also requires administrator privileges. At other times, Give users lower privileges.
So why use it? This is to let users stay away from hackers. If an attacker takes an attack on the browser with an unrepaired bug, he will steal the user's privileges. Because users can install software, hackers can do it. So what happens? The hackers will “own” your computer and embed some Trojans or worms on it, as well as some hidden spyware.
Many Windows users have always been running Windows as an administrator, because Microsoft has never made a difference between administrators and non-admins in the past. In fact, if you have lower privileges, it will be more difficult to work.
Faced with an increasing and fascinating attack. But why wait for it? Take a look at the two methods described below, you can make your Windows XP, set to an earlier version of Windows, get a protection like UAC.
Method 1: Use restricted users
At first glance, you may think that setting up a non-administrator account in Windows is easy to be ridiculous, and you may want to know What's the fuss about Vista and its UAC.
Yes, you can easily set up a low-privileged account in the user account of the control panel with a few clicks. Here, when you click “Create a new account" and give this account a name, please set it to “restricted" before creating.
When this operation is completed, —— is like working in a restricted account in XP. When you are installing Windows XP or using a new computer, if you use the system of the first account, work for a while. Time, you will find that your previous practice is simply the beginning of a nightmare.
You won't be able to access the documents you previously stored in “My Documents> because this folder is now locked under the admin account. Some of the programs you have installed before will disappear mysteriously. At this point, the entire operating system is like a version that takes a long time to re-customize. For example, Firefox, its plugin will disappear, and Word will return to its standard configuration. You have to spend hours re-creating these settings when you run XP as an administrator.
Not to mention that there will be some applications that you will not be able to install at all unless you are under an administrator account. Or they can be installed, but it will refuse to run without administrator privileges. You should avoid this situation by simply right clicking on the installation file and choosing to run as administrator and enter the password, but this is not necessarily a valid way.
Note: There is no way to do this because this method is too much trouble.
Method 2: Use "Run Mode"
Windows XP has a command called "Run Mode" which allows you to temporarily borrow other accounts to run the application. Usually it is used when a restricted account wants to temporarily use administrator privileges, for example, when installing a program.
You can think of these things as the protection provided by UAC in Vista.
Its philosophy is to use malware attacks when you run the most vulnerable applications ——browser and email, when you are a restricted user, even if the worst happens, the malware attack Your application, it can't take its evil to the extreme.
For this method to work, you can run your browser and email client as a restricted user while other programs are running as administrators. This will reduce a lot of problems caused by installing or opening a program, and will allow you to maintain the current settings for the application, as well as the date file path and so on.
For example, right-click on the IE shortcut on the desktop and select “Run as” from the menu in Windows Explorer or Quick Launch Bar. Then enter or select a restricted user account in the user below, and enter the password and click “OK”.
You can automate this process so you don't have to right click each time to do it. Right-click on the shortcut and select “properties", click the “shortcut” tab, then click the “Advanced” button. Hook to select “Run as other user" and click “OK”. From now on, when you open the program from this shortcut, the first thing you will see is an account dialog. Once again, you can choose to run as an administrator or as another account. Here, we are talking about It is necessary to choose a limited account.
