Um update silencioso que Microsoft desdobrado extensamente em julho e em agosto esteja impedindo que a característica do “reparo” de Windows XP termine com sucesso.

Sempre desde que o download recente da companhia de Redmond da sustentação nova arquiva para o Update de Windows, os usuários da função do reparo de XP foram incapazes de instalar os 80 remendos os mais atrasados de Microsoft.

As instalações reparadas de XP não podem ser updated

O problema ocorre quando os usuários reinstalam limas de sistema de XP usando a potencialidade do reparo encontrada nos CD-ROMs genuínos de XP. (A característica não está atual do “em CD Restore. ”) A opção do reparo, que é empregada tipicamente quando XP para alguma razão se torna unbootable, rola muitos aspectos de XP para trás a um estado pristine. Limpa para fora muitos updates e remendos e ajusta o Internet Explorer para trás à versão que enviou originalmente com o sistema se operando. (mais…)

Eu sou indebted ao Web site excelente dos segredos de Windows para a notícia de um desenvolvimento alarming último agosto que envolve Windows XP e Vista que instala silenciosamente limas executáveis, mesmo que os usuários incapacitem updates automáticos. As limas do fare nove foram identificadas assim, pode haver mais, e whilst as limas parecem ser benignas levanta a pergunta muito séria sobre programas de carregamento de Microsoft em PCes sem conhecimento ou permissão dos usuários.

The file downloads occur when users select the ‘Let me choose when to install or notify me but don’t automatically download or install’ option in Security Centre. The revelation appears to have embarrassed Microsoft into issuing an explanation and guarded apology, which basically says that whilst deselecting Automatic Updates does indeed stop any new updates, it doesn’t stop Windows Update updating itself.

It’s important to note that there is no reason to remove or roll back the updated support files that Windows Update may have installed on a PC. There’s no evidence that these files are harmful or cause any software conflicts.

Furthermore, if you use a corporate patch management solution, such as Microsoft’s WSUS (Windows Server Update Services), you circumvent Windows Update and no files will be installed by WU.

But if you’re an individual or a small business using Windows Update (or its enhanced sibling, Microsoft Update), you may be concerned about Microsoft installing patches before you’ve had a chance to research their reliability. In that case, you can completely turn off the Automatic Updates Agent, thereby preventing updates or even notifications from occurring. (more…)

Just received the following that is related to the SVCHOST issues that I’ve written about in the past…

MS has released “Microsoft Security Advisory (927891) - Fix for Windows Installer (MSI)” that’s not really a direct security concern, but actually addresses concerns that might prevent people from getting critical security or other updates.

As previously mentioned, it involves MS KB 927891 - “You receive an access violation error and the system may appear to become unresponsive when you try to install an update from Windows Update or from Microsoft Update“, and the current revision of the article (8.0) states “This fix is one component of a two-part fix that includes a Windows Update client software update. These updates will be deployed automatically using Windows Update in May 2007 and June 2007.”

Again, this update is one of two that need to be applied to fully address the issue. The other update is version 3.0 of the Windows Update Client Software, available from MS KB 932494, “When you use Automatic Updates to scan for updates or to apply updates to applications that use Windows Installer, you experience issues that involve the Svchost.exe process“.

Previously (here and here), I’ve written about isolating shared services so that they run in their own process, with a specific focus on the Windows Update Automatic Updates Service (wuauserv) that typically runs in the NETSVCS SVCHOST.EXE instance. One thing that can be done once this is accomplished is to lower the priority of the process so that when the service winds up consuming 100% of the CPU, the system doesn’t become unresponsive.

Since we’re dealing with a service, setting the priority of such a SVCHOST.EXE process can become problematic - the service may already be running, or, because it is a service, it is not started as non-service processes are, so one is not able to use START / [LOW NORMAL HIGH REALTIME ABOVENORMAL BELOWNORMAL] to impose a priority when the process starts. One can use a utility like Task Manager or Process Explorer to set the priority of a process on an ad hoc basis, but when the service restarts or the system reboots one has to remember to set the priority again.

Though not an ideal solution the following scripts (VBS using WMI, and PowerShell) can be used to set the

In the past, I’ve written about both high CPU utilization by SVCHOST.EXE as well as the 0×8ddd0009 Windows Update / Microsoft Update error, so I thought I would mention this…

MS KB 932494 (When you use Automatic Updates to scan for updates or to apply updates to applications that use Windows Installer, you experience issues that involve the Svchost.exe process) references problems that are addressed by MS KB 916089 (FIX: When you run Windows Update to scan for updates that use Windows Installer, including Office updates, CPU utilization may reach 100 percent for prolonged periods) and MS KB 927891 (You receive an access violation when you try to install an update from Windows Update after you apply hotfix package 916089). However, even after applying the patch associated with 927891 (which replaces the patch associated with 916089), 932494 indicates that the following problems remain:

1) Certain 100 percent CPU issues are still present when you use the Svchost.exe process.
2) An access violation may occur in the Svchost.exe process.

I (as well as others) have speculated in the past that 916089 (and its succedent patches) can also help with the 0×8ddd0009 error…
