En el din\u00e1mico mundo de las TI, mantener y gestionar la seguridad de los sistemas es primordial. Un aspecto importante de esto es garantizar que las cuentas cr\u00edticas del sistema, como la cuenta de administrador en las m\u00e1quinas Windows, sean menos predecibles. Una forma principal de reforzar la seguridad de esta cuenta es cambiarle el nombre. Esto no s\u00f3lo reduce la superficie de ataques de fuerza bruta, sino que tambi\u00e9n dificulta que entidades maliciosas adivinen nombres de usuario est\u00e1ndar. Descubre un script PowerShell que te permitir\u00e1 cambiar un nombre de administrador en Windows<\/strong>.<\/p>\n
