After the operating system is reinstalled, due to problems such as security settings and failure to install patches in time, it is most likely to lead to a large-scale invasion of viruses. Therefore, some essential supplementary measures are very critical. "Northern Network" gave 10 suggestions in the article "New systems are most likely to be poisoned, and you need to do ten major things after reinstalling the system", which is worth learning from.
The first big thing: Don't rush to access the network
After installing Windows, do not connect the server to the network immediately, because the server has not been patched at this time, and there are various vulnerabilities, which are very prone to virus infection and invasion. At this time, add shock wave and shock wave patches and restart before connecting to the Internet.
The second major event: Patch the system/install antivirus software
Needless to say, the patches for shock wave and shock wave viruses must be installed. If you install Windows XP SP2, you don’t need to install them separately.
After installing the system, be sure to install anti-virus software and update it to the latest version.
The third major event: Turn off the system and restore it
System restore is a feature in Windows ME, Windows XP, and Windows 2003. It allows us to restore the system to a certain state of time, thus preventing us from reinstalling the operating system. However, after performing system restoration, some people found that except for disk C, other disk D and disk E have been restored to their previous state, and the files saved in them are gone, causing serious losses!
This is because system restore is based on default for all partitions on the hard disk, so that once the system restore operation is performed, the data of all partitions will be restored. Therefore, we have to press the Win+Break key, then click the "System Restore" tab, cancel the "Close System Restore on All Drives" option, then select the D drive, click the "Settings" button, and select the "Close System Restore on This Drive" option in the open window.
Restore and turn off the system 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 drive, but at the same time, the files on other drives will not be a problem.
The 4th big event: Password for Administrator
Some people may use the system installed by downloading the universal Ghost version online, or they may use the system installed by Windows XP unattended installation CD. When installing these methods, it is very likely that you do not specify the Administrator password, or the Administrator password is the default 123456 or is simply empty. Such a password is quite dangerous. Therefore, after installing the system, please right-click "My Computer", select "Admin", and then select "Computer Management (Local) → System Tools → Local Users and Groups → Users" on the left, select Administrator in the window on the right, right-click, and select "Set Password".
Click the "Continue" button in the open window to set a password for Administrator in the open window.
In addition, select "New User", set the user name and password, and then double-click the new user, click the "Affiliate" tab, select all groups (if any) of them, and click the "Delete" button below. Click the "Add" button again, then click the "Advanced" button in the open window, then click the "Find Now" button to find the PowerUser or User group, click "OK" twice, and add this user to the PowerUser or User group. Log out of the current user and then log in as a new user to find that the system is much faster.
The 5th big thing: Turn off the default sharing
After Windows is installed, some hidden shares will be created, which are mainly used when the administrator is remotely logged in when the system is managed, but for individual users, this is rarely used and is not very safe. Therefore, it is necessary to cut off this sharing: first create a new file under d: and write the following statement in it:
@echo off
net share C$/del
net share d$/del
netshare ipc$/del
net share admin$ /del
Next? Copy d: to C:WINDOWSSystem32GroupPolicyUserScriptsLogon folder. Then press Win+R, enter, expand the "User Configuration → Windows Settings → Scripts (Login/Login)" folder in the open window, double-click the "Login" item in the right pane, in the pop-up window, click the "Add" command, and select the file under the WINDOWSSystem32GroupPolicyUserScriptsLogon folder.
After completing the above settings, restart the system and you can automatically cut off the default shared channel of Windows XP. If you have more hard disks, please add it yourself under net share d$/del, such as net share e$/del, net share f$/del, etc.
The 6th big thing: Enable DMA transmission mode
After enabling DMA mode, the peripheral devices around the computer (mainly referring to the hard disk) can directly exchange data with the memory, which can speed up the reading and writing speed of the hard disk and improve the data transmission rate: Open "Device Manager", where "Main IDE Channel" and "Second IDE Channel" are "Second IDE Channel" and "Second IDE Channel" under "IDE ATA/ATAPI Controller". Double-click it and click "Advanced Settings". This dialog box will list the transmission mode of the current IDE interface connected to the device, and click the list button to set "Transfer Mode" to "DMA (if available). Restart the computer and take effect.
The 7th big thing: Enable advanced power management
Sometimes, before installing Windows XP, you will find that the advanced power control in the BIOS power supply is not turned on. After installing Windows XP, the power supply will not automatically disconnect when turning off Windows. At this time, many people chose to re-turn the advanced power control in the BIOS and re-install Windows XP. In fact, there is no need to be such a hassle. As long as you confirm that you have turned on the advanced power control option in the BIOS and select ACPI Pc at the same time, do not choose the wrong one. Otherwise, you may not be able to enter Windows after restarting and restart the computer. The computer may search and automatically reinstall the computer's hardware, and then it can support advanced power control.
The 8th major event: Cancel the support for compressed folders
Click Start → Run, enter "regsvr32 /u" to enter, and the prompt window "Dll UnrgisterServer in" appears to cancel the compressed folder support for Windows XP. In addition, entering regsvr32 can cancel the association of "pictures and faxes" with the image file.
9th big event: Cancel the "Insufficient Disk Space" notice
Windows XP will issue a notification that "disk space is insufficient" when the capacity of the disk drive is less than 200MB, which is very annoying. You can open the "Registration Editor", locate the HKEY_CURRENT_USERSoftwareMi crosoft WindowsCurrentVersionPolicies Explorer, right-click on "Explorer", select "New" → "DWORD Value" on the right-click menu, name this value "NoLowDiskSpaceChecks", and double-click the value to set "Numerical Data" to "1".
The 10th big thing: Enable verification code
After installing SP2, most users find that when accessing some places where verification codes need to be filled in, the verification code picture cannot be displayed (shown as a small red fork), which is a very serious bug. The solution is: run the "Regedit" command to open the registry editor, locate "[HKEY_LOCAL_MACHINESOFTWAREMicrosoft Internet Explorer Security]", and create a new REG_DWORD value named "BlockXBM" on the right side of the window, and set its value to "0" (hexadecimal value).
The first big thing: Don't rush to access the network
After installing Windows, do not connect the server to the network immediately, because the server has not been patched at this time, and there are various vulnerabilities, which are very prone to virus infection and invasion. At this time, add shock wave and shock wave patches and restart before connecting to the Internet.
