Windows XP system Security Tips

1, restore the damaged WinXP system files

If Windows XP system files are damaged by viruses or other causes, we can recover the corrupted files from the Windows XP installation disk.

How to: Search for corrupted files in Windows XP installation disk, it should be noted that the last character of the filename is replaced with the bottom line "_", for example: If you want to search "Notepad.exe" you need to use "notepad.ex_" to search.

After the search has been made, open the command line mode (enter "cmd" in "Run") and enter: "Expand the full path to the full path destination file for the source file." For example: EXPANDD:SETUPNOTEPAD.EX_C:WindowsNOTEPAD.EXE. One thing to note is that if there are spaces in the path, you need to include the paths in double quotes (English quotes).

It's certainly the best to find, but sometimes we can't find the files we need when we search the Windows XP disk. One reason for this is that the file you are looking for is in a "CAB" file. Because Windows XP treats "Cab" as a folder, for Windows XP, just drag the "cab" file to the right and copy it to the appropriate directory.

If you are using a different Windows platform, search for a "CAB" file that contains the destination file name. Then open the command line mode and enter: "extract/l the full path of the CAB file for the destination location", for example: Extract/lc:windowsd:i386driver.cabnotepad.exe. As with previous faces, you need to include the path in double quotes, as if there were spaces in the path.

2. Reject "Group similar taskbar"

Although the Windows XP "group similar taskbar button" setting allows you to keep your taskbar open and clean, it is very inconvenient to have several windows that need to be opened. If you are often using QQ such as communication software and people chat online, if you have more than two friends talking to you at the same time, you'll immediately feel the inconvenience of the XP default. DD, each time you want to switch to a conversation, click on the group and then the pop-up menu to select the best friend to talk to, And each friend in the group display is the same icon, the conversation object, you may have to click to see exactly who has replied, waiting for you to respond, and choose the wrong one, and have to start from the group election, very troublesome. Obviously, this is less than the original open a few windows, in the taskbar in each small window click once can start chatting. How to change: Click the "start → control Panel → appearance and theme → Taskbar and ' Start ' menu", in the pop-up window, the "Group similar taskbar button" option in front of the hook to remove.

3, through the registry uninstall useless dynamic Link

In order to eliminate this phenomenon, resource managers often leave useless dynamic links in memory, and you can open Registry Editor and set key values: Hkey_local_ Machinesoftwaremicrosoftwindowscurrentversionexploreralwaysunloaddll=dword:1 it to 0, this feature will be turned off. Note: The computer needs to be restarted in order for the settings to take effect.

4, clear the Prefetch folder in the pre-read files

When WinXP is used for a period of time, the files in the Prefetch folder become large and there are dead chain files, which slows down the system time. Recommendation: Delete these files periodically. (Windowsprefetch)

5. Windows XP Weight Loss method

The following methods for my current WinXP weight loss method, after use, feel more safe, the effect is obvious, at least can reduce 300m space. Note: Beginners are not recommended for use.

To delete a driver backup: Driver.cab file (73MB) in the WindowsDrivercachei386 directory but later we must insert the Windows installation disc each time we install new hardware.

Delete system file backups (generally not used): Run the command line Sfc/purgecache

Delete the alternate DLL file: You can do this if you copy the installation files or have the CD-ROM installed. Windowssystem32dllcache the file (minus 200--300MB).

6. Understand WinXP start time

Despite the fact that Windows XP is starting to be a little more satisfying, Microsoft still provides us with a gadget for understanding the startup time that Windows XP starts with, as well as viewing CPU usage, DISKI/O, and so on, because the tool is graphically displayed, So at a glance. Tools are available to download here.

7, restore EXE file association

EXE file association error is very troublesome, because this kind of situation is caused by the virus, and anti-virus software main files are exe file, since EXE file association error, how can run get antivirus software? Luckily XP provides a command-line tool in Safe mode for us to use, You can use command-line tools to solve this problem.

Enter:assoc< spaces >.exe=exefile< Enter in Safe mode, and ". Exe=exefile" will be displayed on the screen. Now close the Command Prompt window, press Ctrl+alt+del to bring up the Windows Security window, press the "Shutdown" button, select the "Restart" option, in normal mode when you start Windows, all of the EXE files can be run properly!

8, let WinXP can automatically update

When Windows has an update, the Automatic Updates system prompts you for Windows upgrades, which, of course, will have a real effect after the Internet. One thing is for sure, if you want to implement Automatic Updates, the system will collect the user's computer information and then send it to the Microsoft site to determine whether you want to upgrade by feedback. This setting is also in the System Properties window, switch to the Automatic Updates tab to see that there are three choices, choose the last "Turn off Automatic Updates", so that the system will not appear often prompted you to automatically update, if you do not use the genuine Windows XP operating system, we recommend that you turn off this feature, Because he may let you upgrade the system to the WindowsXPSP2 version without knowing it, which will cause the system to be unstable.

9. Install IIS in the home version

As you know, the Windowsxphome version cannot install IIS or PWS. In the usual way, you can only upgrade to xpprofessional or use Windows2000, but with a little bit of means, you'll be able to install IIS on Windowsxphome.

First enter "C:windowsinfsysoc.inf" in "Run" on the Start menu, and the system automatically opens sysoc.inf this file with Notepad. Find the "[Components]" section in Sysoc.inf and continue to find a line of words like "iis=iis.dll,ocentry,iis.inf,hide,7", replacing this line with "iis= iis2.dll,ocentry,iis2.inf,,7 ". Save and close afterwards.

Insert the Windows2000professional CD into the optical drive and press SHIFT to prevent the CD drive from running automatically. Enter "CMD" in the Run and return, open command-line mode, enter the following two commands at the command line, and return at the end of each line (assuming the CD drive is D):

EXPandd:i386iis.dl_c:Windowssystem32setupiis2.dll

EXPandd:i386iis.in_c:Windowsinfiis2.inf

At this point, open your Control panel and click the "Add Removal Program" icon, then click "Add Remove Windows Component".

Look carefully, the operating system shown on the Start menu is windowsxphome, but after modification, you have the option to add IIS.

You can then add IIS to the Windowsxpprofessional or Windows2000 method, in this case we only have the WWW service installed. The system will start copying files, which will take some time. And for that, keep the windows2000professional disc in the CD-ROM.

At the end of the installation, you can open the control Panel → performance and options → administrative tools, and Internet Information Services management has already appeared there.

If you want to verify that IIS is working properly, open IE, enter "http://localhost" in the Address bar, and return to the Tu San, if you can see the interface, then all of your IIS will run correctly.

Finally, a little note: If you are in the process of installation, the system needs you to insert windowwhistlercd or need you to provide exch_adsiisex.dll this file, it is because you follow the default option to install IIS. To solve this problem, simply click "Details" when installing IIS, and then deselect SMTP (i.e. do not install an SMTP server), then the two files will not be required to copy the files.

If you have installed the location of Figure 1 and found that the Internet Information Services (IIS) installation project has been shown, but they cannot be selected at all, it is likely that the Iis.dl_ and iis.in_ you are using are removed from the windowsxpprofessional. You can continue normal installation as long as you replace it with windows2000professional.
