Roma - A quanto pare l'aggiornamento silente (http://punto-informatico.it/p.aspx?i=2065674) a Windows Update di cui si è parlato la scorsa settimana non è poi così innocuo.
Scott Dunn riporta infatti in questo approfondimento (http://windowssecrets.com/2007/09/27/03-Stealth-Windows-update-prevents-XP-repair) apparso su windowssecrets.com che l'aggiornamento impedisce, almeno in una circostanza, di scaricare le patch di sicurezza da Windows Update.
In estrema sintesi, gli utenti che dopo l'update silente hanno riparato Windows XP utilizzando il CD d'installazione del sistema operativo, non sono più in grado di ricevere e applicare le ultime 80 patch presenti su Windows Update. Il motivo, secondo Dunn, è che i file DLL che l'update silente ha installato nel sistema non sono stati registrati correttamente: ciò fa inceppare Windows Update, generando l'errore generico "Un problema nel vostro computer impedisce il download e l'installazione degli aggiornamenti".
Per ripristinare la piena funzionalità del sistema di aggiornamenti automatici, è necessario provvedere a registrare manualmente le DLL incriminate (versione 7.0.6000.381). Le istruzioni sono contenute nel succitato articolo di windowssecrets.com.

Manually registering files solves the problem
If you find that Windows Update refuses to install most patches, you can register its missing DLLs yourself. This can be accomplished by manually entering seven commands (shown in Step 2, below) at a command prompt. If you need to run the fix on multiple machines, it's easiest to use a batch file, as Steps 1 through 5 explain:
Step 1. Open Notepad (or any text editor).
Step 2. Copy and paste the following command lines into the Notepad window (the /s switch runs the commands silently, freeing you from having to press Enter after each line):
regsvr32 /s wuapi.dll
regsvr32 /s wuaueng1.dll
regsvr32 /s wuaueng.dll
regsvr32 /s wucltui.dll
regsvr32 /s wups2.dll
regsvr32 /s wups.dll
regsvr32 /s wuweb.dll
Step 3. Save the file to your desktop, using a .bat or .cmd extension.
Step 4. Double-click the icon of the .bat or .cmd file.
Step 5. A command window will open, run the commands, and then close.
The next time you visit the Windows Update site, you should not have any problem installing the latest patches.
In my articles in the last two weeks on the silent installation of the Windows Update support files, I stated that the stealthy upgrade seemed harmless. Now that we know that version .381 prevents a repaired instance of XP from getting critical patches, "harmless" no longer describes the situation. The crippling of Windows Update illustrates why many computer professionals demand to review updates for software conflicts before widely installing upgrades.
"I understand the need to update the infrastructure for Windows Update," says Gordon Pegue, systems administrator for Chavez Grieves Engineers, a structural engineering firm in Albuquerque, N.M. "But I think Microsoft dropped the ball a little bit communicating how the system works. Administrators should know these sorts of things, in case problems arise."
A Microsoft spokeswoman offered to provide an official response about the situation, but I received no reply by press time.
If you ever need to run the repair option on XP, first see the detailed description provided by the Michael Stevens Tech Web site.
I'd like to thank Windows Secrets contributing editor Susan Bradley for her help in bringing reports of this problem to light.
