A batch file is a file that injects commands directly into a computer whenever it is opened. You make a batch file by typing commands into a text editor and saving the file as a .BAT instead of saving it as a text file. Notepad, which comes with Windows, is a basic text editor commonly used to make batch files. To make a batch file in Notepad, you would type the commands you wanted in the batch file, and then you would click File, then Save As, then click Save As Type and change it to All Files. This makes it so you can make your own file ending, like .BAT, instead of the default in Notepad, .TXT, which is a text file. Then, you would save it like you normally would, but put .BAT at the end. This makes it a batch file.
    Now that you can make batch files, you need to know how to make commands. Commands for batch files are sorted into large categories, like NET and IPCONFIG. Then, those groups have subcategories, like NET has USER and LOCALGROUP, both of which we will be using to make an administrator account. Those subcategories then have objects. USER has all the usernames on the computer and LOCALGROUP has all the groups on the computer, like Administrators and normal Users. The commands in batch files are typed like this, for what we need to do to make a batch file: CATEGORY SUBCATEGORY OBJECT /PARAMETER. An example is NET USER HARRY /DELETE. This would go into the category NET, find the subcategory USER, find the object HARRY, which would be a username on the computer, and then delete it with the parameter /DELETE.
    There are two steps to making an administrator account. First, you need to make an account, and second, you need to put that account in the group Administrators. To make an account, you need to build a command starting with NET. NET is the category that has information about the computer, like its users, their passwords, and groups like Administrators and Users. Then, we have to go to USER in NET. This accesses the users. Then, we make a new object named NEWUSER and add the parameter /ADD. This adds a new user named NEWUSER. The whole command is this: NET USER NEWUSER /ADD. What I did specifically, however, was NET USER MUDKIPZ /ADD. Next, we need to make this new user an administrator.
    The command to make an administrator is similar. It starts with NET, to access the computer’s information. Then, you add LOCALGROUP to make it access the groups like Administrators and Users. You add the object ADMINISTRATORS, to access the group Administrators, and then you add a second object, NEWUSER, the user we just created. Then, add the parameter /ADD, to add the user NEWUSER to the group ADMINISTRATORS. The whole command is NET LOCALGROUP ADMINISTRATORS NEWUSER /ADD. What I did to make MUDKIPZ an administrator was NET LOCALGROUP ADMINISTRATORS MUDKIPZ /ADD.
    Now all the commands are built, you need to save the file as a batch file using the instructions in the first paragraph. Whenever you open the newly-created batch file, a new user named NEWUSER is created, and then added to the group Administrators.
