-endpoint y la zona `privatelink.file.<sufijo-de-Azure>` ligada a la VNet. El

-dominio a los clientes P2S para que el nombre de Azure Files resuelva a la IP
-privada. La cuenta de staging usada para transferir paquetes no se reutiliza ni

+Los clientes de un endpoint privado requieren P2S u otra ruta privada a la VNet.
+Un endpoint público exige resolución DNS, salida TCP 445 y reglas de red de

+para endpoint privado y `CloudCache` para uno público. `CCDLocations` y
+`VHDLocations` son mutuamente excluyentes.

-Los clientes deben usar el P2S de Azure o disponer de otra ruta privada a la

+## Riesgos que deben aceptarse

-## 1. Desplegar la infraestructura
+El piloto de septiembre de 2026 confirmó que esta función puede aumentar de
+forma considerable el tiempo de inicio y cierre de sesión. Antes de activarla se
+deben aceptar y probar, como mínimo, estos escenarios:

-El soporte está activado por omisión para despliegues P2S:
+- latencia o indisponibilidad de Azure Files que mantiene `Welcome` o `Sign out`
+  durante varios minutos;
+- VHDX remoto en estado abierto, pendiente de eliminación o de creación, con
+  fallos como `0x80070050`;
+- caché o proxy local obsoleto de Cloud Cache y fallos de registro como
+  `0xE000000B`;
+- recuperación que puede exigir detener por fuerza los servicios FSLogix y
+  reiniciar el equipo;
+- datos todavía no sincronizados, caché local insuficiente o divergencia si se
+  fuerza una recuperación;
+- dependencia de DNS, Kerberos, TCP 445, la red y el servicio de Storage tanto
+  para registrar como para desmontar el perfil.
+
+No se debe desplegar a todos los usuarios sin un piloto de inicio, cierre,
+desconexión, cuota, restauración y pérdida temporal del proveedor. Cloud Cache
+reduce I/O WAN síncrono, pero no elimina la dependencia al cerrar sesión.

-## 3. Instalar FSLogix en las imágenes Windows
-
-FSLogix no forma parte de Windows y su licencia debe validarse para las ediciones
-y suscripciones usadas. Descargue `FSLogixAppsSetup.exe` directamente de
-Microsoft y agréguelo a la imagen base, o páselo como quinto argumento al
-enrolamiento Azure:
-
-```bat
-Start-SguAzureClientEnrollment.cmd 10.77.0.4 C:\SGU\vpn.zip C:\SGU\client.pfx C:\SGU\root.cer C:\SGU\FSLogixAppsSetup.exe
+```powershell
+$parameters.EndpointAccess = 'Public'
+$parameters.StaffProfileStorageMode = 'Auto'
+.\payload\scripts\Enable-SguAzureUserRoaming.ps1 @parameters
 ```

-`Install-SguFsLogix.ps1` exige una firma Authenticode válida de Microsoft,
-instala silenciosamente sin reiniciar y comprueba `frxsvc` y `frx.exe`. Si la
-imagen ya contiene FSLogix, el instalador puede omitirse. Microsoft recomienda
-mantener la versión más reciente; FSLogix no se actualiza mediante Windows
-Update.
+El script crea las GPO `SGU - AL redirected folders` y `SGU - AD-DO FSLogix
+profiles`, y vuelve a habilitar el enlace de instalación de FSLogix si ya existe.
+No borra perfiles locales existentes salvo que se proporcione deliberadamente
+`-DeleteExistingStaffLocalProfiles`.

+FSLogix no forma parte de Windows. Valide su licencia y descargue
+`FSLogixAppsSetup.exe` directamente de Microsoft. Puede pasarse como quinto
+argumento al enrolamiento Azure o publicarse con:
+
+```powershell
+.\payload\scripts\Publish-SguFsLogixClientDeployment.ps1
+```
+
+El publicador valida firma y SHA-256 y crea `SGU - FSLogix client deployment`.
+El rollback descrito abajo deshabilita su enlace para que no se instale en más
+equipos.
+
+## 4. Desactivar y volver a perfiles locales
+
+Ejecute desde Windows PowerShell 5.1 elevado en el controlador de dominio:
+
+```powershell
+.\payload\scripts\Disable-SguAzureUserRoaming.ps1
+```
+
+Es idempotente y realiza lo siguiente:
+
+- fija `Profiles\Enabled=0` y `ODFC\Enabled=0`;
+- deshabilita `frxsvc` y `frxccds` mediante GPO;
+- elimina `CCDLocations`, `VHDLocations` y valores de contenedor específicos de
+  los grupos `SGU-Administrativos` y `SGU-Docentes`;
+- restaura Escritorio y Documentos de alumnos a
+  `%USERPROFILE%\Desktop` y `%USERPROFILE%\Documents`;
+- deshabilita el enlace de despliegue del cliente FSLogix;
+- limpia `profilePath`, `homeDirectory` y `homeDrive` de los usuarios de las OU
+  SGU, salvo que se use `-PreserveLegacyUserMappings`.
+
+Después aplique `gpupdate /force` y reinicie cada Windows administrado antes de
+probar un nuevo inicio de sesión. El primer ingreso vuelve a crear o reutilizar
+un perfil local. El script no borra automáticamente VHDX, shares de Azure ni
+cachés existentes: conservarlos permite recuperación y evita destrucción de
+datos. Su eliminación debe ser una decisión separada y posterior a la validación.
+
+## 5. Validar un piloto futuro
+
+Después de `gpupdate /force` y reiniciar un cliente de prueba:

 ```powershell
 Resolve-DnsName "$($azure.UserRoamingStorageAccountName).file.core.windows.net"
 Test-NetConnection "$($azure.UserRoamingStorageAccountName).file.core.windows.net" -Port 445
 Get-Service frxsvc
-Get-ItemProperty 'HKLM:\SOFTWARE\FSLogix\Profiles'
+Get-ItemProperty 'HKLM:\SOFTWARE\FSLogix\Profiles\ObjectSpecific\<SID-del-grupo>'
 & 'C:\Program Files\FSLogix\Apps\frx.exe' list-redirects
 ```

-La resolución debe devolver la IP privada del endpoint. Inicie primero con un
-`AL` nuevo y confirme las ubicaciones de Escritorio/Documentos; luego pruebe un
-`AD` o `DO` sin perfil local previo y confirme la creación de un VHDX en
-`profiles`. No active el borrado de perfiles locales ni despliegue a todos los
-usuarios hasta probar inicio, cierre, desconexión de VPN, cuota y restauración.
+Revise `%ProgramData%\FSLogix\Logs\Profile`, pruebe inicio y cierre varias veces,
+simule indisponibilidad y valide restauración. No active el borrado de perfiles
+locales ni amplíe el alcance antes de superar esas pruebas.
