After the operating system reinstall, because the security settings and patches are not in time to install problems, the most likely to cause the virus to invade, so some necessary complementary measures is very critical.
First, do not rush to access the network
After the installation of Windows, do not immediately put the server into the network, because at this time the server has not hit a variety of patches, there are various vulnerabilities, very vulnerable to infection and intrusion. At this point to add shock waves and shock wave patch and restart again into the Internet.
Second, to the system to patch/install anti-virus software
Needless to say, shockwave and shock wave virus patches are sure to hit, if you install Windows XP SP2 will not have to install separately.
After installing the system, be sure to install anti-virus software and update it to the latest version.
Third, turn off System Restore
System Restore is a feature in Windows Me and Windows XP, Windows 2003, which allows us to restore the system to a certain time state so that we can avoid reinstalling the operating system. However, some people in the implementation of the System Restore, found in addition to C disk, the other D-disk, e-disk have been restored to the previous state, the results of the saved documents are not, resulting in a serious loss!
This is because System Restore defaults to all partitions on the hard disk, so that once the System Restore operation is made, the data for all partitions will be restored. Therefore, we must press the Win+break key, click the System Restore tab, cancel the Turn off System Restore on all drives option, and then select D, click the Settings button, and select the "Turn off System Restore on this drive" option in the open window.
Turn off System Restore on other disks in turn. In this way, once the system is unstable, you can use the System Restore tool to restore the system on the C disk, but the files on the other disks will be fine.
Four, password for the administrator
Some people may be using a universal Ghost version of the Web to install the system, or may be using the Windows XP unattended installation of the installation of the CD-ROM system, the use of these methods when the installation is very likely not to allow you to specify the administrator password, Or the administrator's password is the default of 123456 or simply null. Such a password is quite dangerous, therefore, after installing the system, right-click "My Computer", select "Manage", then select "Computer Management (local) → system tools → local Users and Groups → users" on the left, select the Administrator in the right window, right-click and select "Set Password".
Click the Continue button in the open window to set the password for the administrator in the open windows.
In addition, select New user, set the username and password, double-click the new user, click the Affiliate tab, select all of the groups (if any), and click the Delete button below. Click the Add button, then click the Advanced button in the Open window, click the Find Now button, locate the PowerUser or user group, and click OK two times to add the user to the PowerUser or Users group. Log off the current user, and then log on with a new user to discover that the system is much faster.
