Windows Installation Disk/USB (Windows 10/8.1/8/7):

These methods might vary based on the Windows version and system configurations. If these built-in methods don’t work or if you're uncomfortable using them, consider seeking assistance from a professional technician or contacting the PC manufacturer's support for guidance on resetting the administrator password.
