There are different levels of accounts available in Windows7, but Microsoft's default recommendation is to use a standard account instead of an admin account. Microsoft's official reply has the following two points:
1. Standard accounts can help protect our computers by preventing users from making changes that affect all users of the computer, such as deleting files needed to work on a computer. It is recommended that you create a standard account for each user.
2. When we log on to windows7 with a standard account, we can perform almost all the operations under the Administrator account, but if you want to perform actions that affect other users of the computer (such as installing software or changing security settings), Windows 7 may require that we provide the password for the administrator account.
In this way, in order to enhance the security of personal computers, we will create a "qualified" Windows7 standard account.
Although the genuine WINDOWS7 system itself is very safe and stable, hackers want to control your computer through the network is very difficult one thing. However, if your Windows 7 Administrator account is not encrypted, you may be able to directly control your computer by simply logging on to the Administrator account on your computer (this may be your computer in an open environment, of course). Adding a password that only you know for the Windows7 administrator account is much more secure.
Just one more step and start creating a Windows 7 standard account now. Under the Windows 7 standard account, the user can use all the software, but if the software program to make changes to the system must be approved by the administrator to the line, so security greatly improved.
The safest way to do this is to create a password for Windows7 's standard account so that you can't view your computer without your permission.
With simple Windows 7 account settings, we can make our computer more secure, generally recommended to use the WINDOWS7 standard account, so that when our computer to lend others to use, we can rest assured that there will be no privacy leakage and security issues, security greatly improved.
