Vista - Windows can't check for updates (pls help!!!)

I have searched through many threads and I have been unable to find an answer.

My windows update is unable to check for updates, an whenever I manually check for updates, Install now shows up, once the installation process begins, a couple of minutes go by and windows returns to checking for updates, and I am right back to Check for updates for your computer.


I've checked the history, and so far KB948610 has failed 4 times, and KB953733 once in the past (windows apparently never tried again).

Has anybody have a clue how I can resolve this???

You may try the suggestions of this tutorial: http://www.vistax64.com/software-too...air-tools.html

I ll check it out. I'll post again if I have a hard time!! Thanks

yeah... you know what, its still giving me that same s*** error 0x800b0100, which I think means unregistered WU or something(i saw a chart on the website with the errors and there meaning, but cant remember exactly). How can I work around or correct that??

Hi There,
I had a similiar problem and one of the threads recommended this
Go to Network and Sharing Centre in Control Panel, once in here locate where your connected at (Linksys, Netgear...etc) to the right it should say View Status click Properties it will prompt you to confirm privilages push continue, while in Networking Tab locate Internet Protocol Ver. 4 highlight and to the right click Properties set preferred DNS to 4.2.2.2. and alternative DNS to 4.2.2.3 and it should work

Did you try this one: Description of the System Update Readiness Tool for Windows Vista and for Windows Server 2008?

Edit: If you think your system is OK, have you run any anti malware programs?

thanks gran and submarine, I've went and specified those DNS numbers (thanks again gran) we'll see if that makes a difference. As far as kb947821, i got to install that one with no fuss, so I've got no clue what the hell is up!! pls reply if you got anything to help me further -------- desperate vista user!!!

as far as malware programs go, i've run CCleaner and registrybooster2, as well as I have shawsecure(a very reliable ISP based virus/spyware detection and removal program along with firewall) I have of course disabled my windows firewall(is that a mistake?) to avoid any conflicts between firewalls

Just to be on the safe side try Malwarebytes, preferably from safe mode. In addition, try either Spybot S&D or SUPERAntiSpyware (in these two cases, make sure not to install anything memory resident, e.g. TeaTimer, as it may interfere with your ordinary AV program). Also test the Vista Malicious Software Removal Tool.

Could the use of registry booster in any way be related to your problem, and in such case, does it make any registry backups? Same question for Ccleaner and would you have a backup from a registry cleaning then?

Edit: If the antimalware programs find nothing, check in Control Panel - Programs - Programs and Features if you have an entry Microsoft .Net Framework and post here the version it is. Also let us know if other security updates installs OK from Windows Update or if these two are the only ones that fails.

Search for msconfig, right click and run as administrator. On the Services tab, make sure Windows Update is ticked. Otherwise tick it, click apply and OK, and reboot. Then search for Services. Run it as administrator and look for Windows Update. Its status should be "Started" and "Startup type" should be Automatic (Delayed start). If not double click and set the startup type to this value and start the service. Reboot and check this again. When running as it should, try windows update again.

I've got some full registry backups from each registrybooster and ccleaner, but the problems themselves originated before (basically ran those programs to correct the issue). I've seen my system performance dramatically increase (web browsing and app loading especially)since ive ran these and the removed files were usually ancient progam tracer(like VAIO startup agent and things of the sort ive already removed when i purchased the laptop).

As far as .NET framework, It's not part of my programs and I've downloaded it and tried to run it, but it will not install. I ran the install overnight and once again, it does not install with a 800b0100 error code.

I've found the graph with what that means and it would be an unsecured signature. I tried to re-register my WU, but that does not seem to fix it.
