Creating users easily and quickly in windows xp

IF it is windows 10:

Create administrator account for Windows 10 with command line As you've lost access to all your user accounts, you can't open a Command Prompt in Windows 10. Therefore, you need to get a Command Prompt and use command lines with the help of a Windows 10 setup/installation disc.

Step 1: Boot your PC from a Windows 10 setup/installation disc.
Tips: If you have no any Windows 10 disc, burn a Windows 10 ISO to a USB or CD/DVD drive to instantly create one.

Step 2: When you get to Windows Setup screen, press Shift + F10 to bring out a cmd.exe dialog. Then execute the following three command lines.

1. Type move d:\windows\system32\utilman.exe d:\windows\system32\utilman.exe.bak and press Enter to make a copy of utilman.exe file.

2. Type copy d:windows\system32\cmd.exe d:\windows\system32\utilman.exe and press Enter to replace utilman.exe file with cmd.exe file.

3. Type wpeutil reboot, press Enter, and disconnect the Windows 10 disc from the computer to reboot Windows 10.
Note: Replace d:\ with your system drive letter.


Step 3: When Windows 10 reboots up and comes to the sign-in screen, click the Ease of Access icon. This should open a Command Prompt dialog because you have replaced the Utilman.exe file with cmd.exe file in the second step above. Then execute the following two command lines to create a new admin account for your Windows 10.

1. Type net user /add [username] [password] and press Enter to create a new user account.

2. Type net localgroup administrators [username] /add and press Enter to add the newly created user account to your Windows 10 administrator group.

Few more Advanced uses of net user command.
To specify user full name while creating the user account

net user username userpasswd /ADD /FULLNAME:"User_Fullname"

To specify that the user is allowed to change the password

net user username userpasswd /ADD /PASSWORDCHG:Yes

To restrict user not to change the password:

net user username userpasswd /ADD /PASSWORDCHG:NO

To specify when the account expires we can use /EXPIRES switch.
To specify if the user must have a password set we can use /PASSWORDREQ switch.
How to create a new administrator account from command line?
An administrator account can't be created directly from command line. We first need to create a user account and then add the user to the administrators group.
Errors:
If you don't have privileges to add new user account to the system, you would get an error like below.C:\>net user John /add
System error 5 has occurred.
Access is denied.

Do you need to reset vista or xp users password? Ihas a little trick that dig it for you from tech-hack forums. The method is very easy to follow and doesn't require any complicated commands. The method is free to use and you don't need to pay hundreds of dollars for some utility for unlocking lost windows passwords. Just follow next simple steps:
First thing you need to do is to start command prompt or CMD. There is two ways to do that:
Press F8 when Windows XP start up (before windows xp logo - progress bar for loading) and choose "Save Mode Command prompt" option
If you are logged in: click on start -> Run, type "cmd" and press ENTER.
In command prompt window type command "net user" or "net users". You will see the list of users that are created on current running OS.
Type "net user" "user name" "*". You will see that windows will ask you to enter new password for that particular user account! No super user privileges needed. Just type new password two times and you are done.
Example of process: If the administrator username is "administrator" then command for changing its password will be: "net user administrator *".
Note: quotes (") in the post are just for highlighting the word.
