After the operating system is reinstalled, due to security settings and patches not being installed in time, it is most likely to cause a virus to invade. Therefore, some necessary supplementary measures are very important. "Northern Network" in the article "The new system is the most vulnerable to poisoning, to do ten major things after reinstalling the system" gives 10 recommendations, it is worth learning. The first big thing: don't rush to access the network After installing Windows, don't immediately connect the server to the network, because the server has not been patched, there are various vulnerabilities, and it is very easy to get infected and invaded. At this point, add the shock wave and shock wave patch and restart and connect to the Internet. The second big thing: patching the system /installing anti-virus software Needless to say, the shock wave and shock wave virus patch must be marked, if you install Windows XP SP2, you do not need to install it separately. After installing the system, be sure to install anti-virus software and update it to the latest version. The third big thing: Turn off System Restore System Restore is a feature in Windows ME and Windows XP, Windows 2003 that allows us to restore the system to a certain time state, thus preventing us from reinstalling the operating system. However, some people after the system restore, found that in addition to the C drive, the other D drive, E drive are restored to the previous state, and the results of the saved files are gone, causing serious losses! This is due to System Restore defaults to all partitions on the hard disk, so once the system restore operation is performed, the data of all partitions will be restored. Therefore, we must press the Win+Break button, then click the "System Restore" tab, cancel the "Turn off System Restore on all drives" option, then select the D drive, click the "Settings" button, select it in the window that opens. "Turn off system restore on this drive" option. Restore the systems on the 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 disks will not be a problem. The fourth big thing: give the Administrator a password
Some people may use the system to download the universal Ghost version to install the system, or it may be the Windows XP unattended installation CD installation system, use these methods It is very likely that you will not be assigned the Administrator password during installation, or the Administrator password will be the default 123456 or simply empty. Such a password is quite dangerous, so after installing the system, right click on "My Computer", select "Manage", then select "Computer Management (Local) → System Tools → Local Users and Groups → User", select Administrator in the right window, right click and select "Set Password". Click the "Continue" button in the open window to set a password for the Administrator in the open window. In addition, select "New User", set the user name and password, double-click the new user, click the "Subordinate to" tab, select all the groups (if any), and click the "Delete" button below. Then click the "Add" button, 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 to add this user to PowerUser or User group. Logging out the current user and logging in as a new user can reveal that the system is much faster. The fifth big thing: Turn off the default share After Windows installation, some hidden shares will be created, which are mainly used when the administrator manages the system when logging in remotely, but for personal users, this is rarely used, and it is not very safe. Therefore, we need to cut off this share: first create a new disshare.bat file under d:, write the following statement: @echo off net share C$/del net share d$/del netshare ipc$/del net Share admin$ /del Next? Copy d:disshare.bat to the C:WINDOWSSystem32GroupPolicyUserScriptsLogon folder. Then press Win+R, enter gpedit.msc, in the open window, expand the "User Configuration → Windows Settings → Script (Login /Logout)" folder, double-click the "Login" item in the right pane, pop up In the window, click the "Add" command and select the disshare.bat file in the C:WindowsSystem32GroupPolicyUserScriptsLogon folder. After completing the above settings, restart the system, you can automatically cut off the default shared channel of Windows XP, if you have more hard drives, please add them under net share d$/del, such as net share e$/del, net share f$/del and so on. The sixth big thing: enable DMA transfer mode After enabling DMA mode, computer peripherals (mainly hard disks) can directly exchange data with the memory, which can speed up the hard disk read and write speed and increase the data transfer rate: open the "Device Manager". Among them, "IDE ATA/ATAPI Controller" has "Main IDE Channel" and "Secondary IDE Channel". Double-click it and click "Advanced Settings". This dialog box will list the transmission mode of the device connected to the current IDE interface. Click the list button to set the Transfer Mode to DMA (if available). Restart your computer to take effect. The 7th big thing: enable advanced power management Sometimes installing Windows XP will find that the advanced power control in the BIOS power is not turned on. After installing Windows XP, the power will not be automatically disconnected when Windows is turned off. At this time, many people chose to re-open the advanced power control in BiOS and reinstall Windows XP. In fact, you don't need such trouble. As long as you confirm that you have turned on the advanced power control option in BiOS and select ACPI Pc, you must not choose the wrong one. Otherwise, you may not be able to enter Windows after restarting, and restart your computer. The computer may search again. And automatically re-install the computer's hardware, then you can support advanced power control. The 8th big thing: cancel the compressed folder support Click Start → Run, type "regsvr32 /u zipfldr.dll" Enter, the prompt window "Dll UnrgisterServer in zipfldr.dll succeeded" can cancel the Windows XP compressed folder stand by. Alternatively, type regsvr32 shdocvw.dll to unlink "pictures and faxes" from the image file. The 9th big thing: cancel the "out of disk space" notification
When the disk drive capacity is less than 200MB, Windows XP will issue a "out of disk space" notification, which is very annoying. You can open the "Registry Editor", navigate to HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPolicIEs Explorer, right click on "Explorer", select "New" → "DWord Value" on the right-click menu, name this value "NoLowDiskSpaceChecks", double-click the value Set "Value data" to "1". The 10th big thing: enable verification code
After installing SP2, most users find that they can't display the verification code picture (shown as a red cross) in some places where they need to fill in the verification code. This is a very serious problem. Bug. The solution is: run the "Regedit" command to open the registry editor, then navigate to "[HKEY_LOCAL_MacHINESOFTWAREMicrosoftInternet Explorer Security]", create a new REG_DWord value named "BlockXBM" on the right side of the window, and set its value to "0". (hexadecimal value).
