Wsus not updating itself
In some cases, the ASM may be installed in networks that do not have Internet access to Microsoft's Windows Update website, therefore the ASM requires an alternative method to download Windows Updates.
This document details how to configure a local Windows Server Update Services (WSUS) Server to permit the ASM to download any necessary updates via a local server.
A quick memory test would also be good, as memory failures are one of the most prevalent physical causes of such problems. If you are unable to enter Safe Mode, chances are the OS is pooched. You could try the rollback methods listed above in the recovery console.
It was Windows that got us into this mess in the first place, so surely now is the time to point the finger of blame at the software side? If you are lucky the updates will finish installing in safe mode, and all you have to do is reboot. If that does not work, try running from the recovery console.
However, with Microsoft's latest stealth move, updates to the WU executables seem to be installed regardless of the settings - without notifying users." As it turns out, Dunn may have been looking in the wrong place.
A brief check of the table of contents on Microsoft's Tech Net reveals a page entitled, "Automatic Updates Must Be Updated." Though there is no explicit sentence here that says, "By the way, the IIS-marshaled update channel still functions even when the option in this dialog box is set to 'Turn off Automatic Updates,"' a fairly knowledgeable person reading this page should be able to deduce that this self-update channel is separate and operative. Shouldn't there be a way for the user to say, "I don't want updates, and I mean I don't want updates! Using the Services panel in Computer Management, a user can very easily switch the active state of Automatic Updates from "Automatic" to "Stopped." A moderately skilled administrator - or certainly any administrator who legitimately received his or her certification - should also be able to disengage WSUS by stopping its service host from the command line.
These upgrades are important if we are to maintain the quality of the service." The discovery, which came as news to many, is that the Windows Update service (known internally as WSUS) updates itself through a separate channel, managed through Internet Information Services.
In Microsoft knowledge-base they say that this is caused by WSUS (Windows Server Update Services).
