   - **tasklist**: muestra los procesos. /M muestra las tareas con sus archivos .exe y .dll. Se puede especificar un módulo en particular. /V muestra las tareas en modo verboso
   - **wmic**: Windows Management Instrumentation Command-line (WMIC). Acceso a la poderosísima Windows Management Instrumentation API de Windows XP/2003/Vista. Es un muy complejo comando con enorme cantidad de opciones. Algunas son: **process** (muestra los procesos y toda la info de los mismos), **process list brief** (lista breve de procesos), **startup list full** (muestra los procesos a iniciar en el arranque), /every:5 (muestra la info cada 5 segundos). Para ver si un proceso aparece, se puede usar el comando **find** (similar al grep) enviándole la salida del wmic cada un segundo: **wmic process list brief /every:1 | find "cmd.exe"**. La **ayuda** se invoca con **/?**. Más info en http://technet.microsoft.com/en-us/library/bb742610.aspx

+===== Reparar con Hiren's CD un Windows con bootmgr perdido =====
+  - Once you open CMD, you have to enter **diskpart** into the window. Then, type **list disk** as well.

+  - In order to make the partition active, you have to enter active into the CMD window.
+  - I hope you know the drive letter containing Windows installation. If you don’t know, follow the commands **diskpart**, **list volume** and exit. Soon after you enter the first command, you can get the list of drives.
+  - If your disk letter is C, type C: into the window. Then use the following commands <code>
+Bootrec /fixmbr

+  - In the left-hand panel, click Server Roles to assign any server roles you want this user to have, including bulkadmin, dbcreator, public, and so on.
+  - In the left-hand panel, click Securables and then click Search.

+  - Grant will grant access to the securable, with grant will allow the user to grant access to the securable and deny will expressly deny permission to the securable no matter what roles or permissions the user may have.
+  - In the left-hand panel, click Status to grant or deny permission to the Database Engine, enable or disable the login and to unlock the account should it get locked out.
+When you have finished modifying the settings, click OK to create the user and exit the new login creation window.
+===== Error de "Corrección de oráculo de cifrado de CredSSP" al conectarse por escritorio remoto (RDP) =====
+El escenario más común es que el cliente tiene instalada la actualización CredSSP y la configuración de directiva de Corrección de oráculo de cifrado no permite una conexión RDP no segura con un servidor que no tenga instalada la actualización CredSSP.
+Para resolver este problema, siga los siguientes pasos:
+En el cliente que tiene instalada la actualización CredSSP, ejecute gpedit.msc y, a continuación, busque Configuración del equipo > Plantillas administrativas > Sistema > Delegación de credenciales en el panel de navegación.
+Cambie la directiva de Corrección de oráculo de cifrado a Habilitado y, a continuación, cambie el Nivel de protección a Vulnerable.
+Si no puede usar gpedit.msc, puede realizar el mismo cambio con el registro de la siguiente manera:
+Abra una ventana del símbolo del sistema como administrador.
+Ejecute el siguiente comando para agregar un valor de registro:
+  REG ADD HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters\ /v AllowEncryptionOracle /t REG_DWORD /d 2
