Problems with imaging devices after uninstalling Logitech drivers

The problem:
After uninstalling Logitech's QuickCam software and drivers, all imaging devices (cameras, webcams, scanners) no longer work in Windows. In the device manager, a yellow exclamation mark icon is displayed, along with this message: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"


The solution:
1) Reboot into safe mode (press F8 at startup), navigate to C:\windows\system32\drivers, and rename the file lvmvdrv.sys to lvmvdrv.sys.backup

2) Open the registry editor (Start > Run > regedit > OK) and in the left pane navigate down to My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlS
et\Control\Class\{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}.

3) Right click that key (the folder icon you just navigated to) and select Export. Save this to your desktop for now. If for some reason things don't work out after all is said and done, you can double click this file and undo the rename from step 1, reboot, and you'll be back where you started.

4) With the key you just exported being selected in the left pane, on the right you should see a Multi String Value named LowerFilters, with lvmvdrv as it's data. Right click this MSV and delete it.

5) Reboot. Your imaging devices should be working now.

You can configure Windows XP to automate the logon process if your computer is not part of a domain.

1.	Click Start, click Run, and type control userpasswords2.
2.	Clear the Users must enter a username and password to use this computer check box.
3.	Click Apply.
4.	Enter the user name and password you wish to automatically log on with, and then click OK.
5.	Click OK again and you're all done.

This feature allows other users to start your computer and use the account that you establish to automatically log on. Enabling auto logon makes your computer more convenient to use, but can pose a security risk.

Impresora no se redirige en Escritorio Remoto o Servicios de Terminal Server

http://support.microsoft.com/kb/302361

Cuando usa una sesión de Escritorio remoto o la versión de cliente 4.0 o 5.0 de Servicios de Terminal Server para conectar con otro equipo basado en Windows desde un equipo que no ejecuta Windows Server 2003, no se pueden redirigir las impresoras locales. En consecuencia, las impresoras locales no están disponibles en el escritorio remoto ni en la sesión de los Servicios de Terminal Server.

Causa

El problema se produce porque el puerto de impresora no empieza con COM, LPT o USB. De manera predeterminada, los nombres de puerto de impresora que no empiezan con COM, LPT o USB sólo se redirigen en Windows Server 2003. De manera predeterminada, los dispositivos de impresión multifuncionales no se pueden redirigir a menos que esté ejecutando Windows Server 2003 en el equipo local porque utilizan puertos DOT4.

Solución

Para resolver este problema en un equipo que no ejecuta Windows Server 2003, fuerce a todos los puertos (incluido DOT4) del equipo cliente a que sean filtrados para redirección. Para ello, agregue un valor DWORD llamado FilterQueueType a HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default\AddIns\RDPDR y configure su información de valor en FFFFFFFF.

Siga estos pasos y después salga del Editor del Registro:

1.	Haga clic en Inicio, en Ejecutar, escriba regedit y, a continuación, haga clic en Aceptar.
2.	Localice y, después, haga clic en la clave siguiente del Registro: HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default\AddIns\RDPDR
3.	En el menú Edición, seleccione Nuevo y haga clic en Valor DWORD.
4.	Escriba FilterQueueType y, a continuación, presione ENTRAR.
5.	En el menú Edición, haga clic en Modificar.
6.	Escriba FFFFFFFF y, después, haga clic en Aceptar.

Esto permite que se redirijan todos los puertos del cliente.

Para evitar este problema en un equipo cliente que tenga un dispositivo de impresión multifuncional, cambie el puerto que usa ese dispositivo de DOT4 a un puerto LPT.

Por ejemplo, para configurar un dispositivo de impresión multifuncional para que use un puerto LPT en un equipo con Windows XP, siga estos pasos:

1.	En Panel de control, abra Impresoras y faxes.
2.	Haga clic con el botón secundario del mouse (ratón) en la impresora local no redirigida y, a continuación, haga clic en Propiedades.
3.	Haga clic en la ficha Puertos, en un puerto LPT y en Aplicar. La impresora debe aparecer ahora junto a ese puerto.
4.	Cierre la ventana Propiedades de impresora y vuelva a conectar utilizando Escritorio remoto.

Importante
Cuando una impresora multifuncional usa un puerto LPT estándar en lugar del puerto DOT4, pierde las capacidades multifuncionales, como escáner, fax o copiadora. Para recuperar las capacidades multifuncionales, el dispositivo de impresora debe usar el puerto DOT4.

Speed up Windows XP Shutdown

Tomado de: http://www.johntp.com/2006/02/14/speed-up-windows-xp-shutdown

Windows XP stores a couple of values in its registry which are responsible for determining how long to wait before shutting down open applications and services once the shutdown command has been given.

By editing these two settings and changing them to lower values, you can considerably decrease the amount of time that Windows XP needs to successfully shut itself down. The first part of this tweak deals with setting the amount of time Windows will take to kill open applications on shutdown.

Open REGEDIT and navigate to

‘HKEY_CURRENT_USER\Control Panel\Desktop\’

Highlight the ‘WaitToKillAppTimeout’ value.
Set it to ‘1000′.

Now highlight the ‘HungAppTimeout’ value
Set it to ‘1000′ also.

The second part of this tip changes the same settings, this time for all users on the system.

Open REGEDIT and navigate to

‘HKEY_USERS\.DEFAULT\Control Panel\Desktop’

Highlight the ‘WaitToKillAppTimeout’ value.
Set it to ‘1000′.

Now highlight the ‘HungAppTimeout’ value.
Set it to ‘1000′ also.

In the third part of this tip, we will alter a second registry setting to decrease the amount of time Windows XP will wait before shutting down active services after receiving a shut down command.

Open REGEDIT and navigate to

‘HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\’

Highlight the value ‘WaitToKillServiceTimeout’

Change this value to ‘1000.’

This should help to considerably speed up the time Windows XP takes to shut itself down.

Auto kill tasks on shutdown

By default, Windows XP will prompt the user for input if there are one or more applications which have crashed or are not responding and it receives a shut down command. This halts the shutdown process entirely until the user approves the stopping of the non-responsive app.

By altering the registry slightly, Windows XP can be set to close crashed applications automatically. While this does not technically speed up the shut down process, it does streamline it, and ensure that the user will not give the shutdown command then get up and leave, only to find the PC still powered on because Windows never received input on what to do with a hung application.

To allow Windows XP to close non-responsive applications automatically upon shutdown:

Open REGEDIT and navigate to

‘HKEY_CURRENT_USER\Control Panel\Desktop’

Highlight the value ‘AutoEndTasks.’

Change the value to ‘1′

XP will now be able to close hung applications without user input during the shutdown process.
