(Nota: %System% es la carpeta del sistema de Windows, que en el caso de Windows 98 y ME suele estar en C:\Windows\System, en el caso de Windows NT y 2000 en C:\WINNT\System32 y en el caso de Windows XP y Server 2003 en C:\Windows\System32).
. %System Root% es la carpeta raíz, normalmente C:\. También es la ubicación del sistema operativo).)
Soluciones
Step 1
Los usuarios de Windows ME y XP, antes de llevar a cabo cualquier exploración, deben comprobar que tienen desactivada la opción Restaurar sistema para permitir la exploración completa del equipo.
Step 2
Reiniciar en modo seguro
Step 3
Eliminar este valor del Registro
Importante: si modifica el Registro de Windows incorrectamente, podría hacer que el sistema funcione mal de manera irreversible. Lleve a cabo este paso solo si sabe cómo hacerlo o si puede contar con ayuda de su administrador del sistema. De lo contrario, lea este artículo de Microsoft antes de modificar el Registro del equipo.
