- when you get that error press Shift + F10 to open a Command Prompt and run the following commands one at a time:
net user Аdministrator /active:yes
The first command activates the built-in administrator account. The second command goes to the location of the oobe directory in system32. The third command launches msoobe.exe utility to reset local settings.
After that the "just a moment" screen will appear:
Wait for a while and if the computer does not reboot itself, force it to reboot. After restart the message "Incorrect username or password" might appear on the screen, ignore it and click "OK". The login window will appear and you will be able to log in as Administrator without any password. Once logged in you can create different user accounts and set up the system as you wish.
