Resetting your computer to factory settings can be a convenient solution to many issues, but doing so without the administrator password can be tricky. Here are some steps you can take:

1. Restart your computer and press the appropriate key (often F8 or Del) to enter the BIOS settings.
2. Look for an option to reset to factory settings within the BIOS menu. Not all computers have this option, but it's worth checking.
3. If the above step doesn't work, you can create a bootable USB drive with a fresh operating system and use that to reset your computer.
4. Another option is to use third-party software that can help reset your computer without the administrator password.

While factory resetting without the administrator password is possible, it's important to note that you may lose all your data in the process. It's always a good idea to back up your important files before proceeding.
