Security Windows

If you’ve tried to install recommended updates in Windows Vista, and receive error 800B0100, this tutorial offers the most common solution to that problem.

windows vista update error 800B0100

  1. The solution, in a nutshell, is to disable your firewall. If you’re using McAfee Personal Firewall Plus, F-Secure Internet Security, Norton Internet Security or another Firewall vendor, see its respective support page for assistance in disabling it (temporarily). If you’re using the built-in Vista Firewall, keep reading.

    Open the Control Panel and select Security.

    I have been reading up on this issue for a long time now. I have two Dell machines – an Inspiron Laptop and a Dimension 9150 Server.

    My laptop upgraded to Sp1 with no problems at all. The Dimension however has been a bit of a pig and I have seen this 800B0100 code for a good long time.

    I have tried pretty much every step I could find, both here on TechNet and elsewhere. Nothing worked.

    edit: Not for nothing, but I am not some noob either, I have been in the industry for 15 years and some of the KB articles offered as resolutions are a complete nightmare even for a *ahem* talented professional, so I’d hate to know how someone without any real experience would cope…

    What I did was quite simple really, a little bit of a pain to accomplish but it’s RESOLVED THE ISSUE FOR ME.

    I simply performed an “in-place upgrade” i.e. re-installed Vista and used the upgrade option.
    Then came the nightmare…

    After re-installing, I ran Windows update and let nature take it’s course…

    After about 6-10 updates and reboots, I was finally offered SP1, which I was finally able to download and install.

    Hope someone, somewhere finds this helpful because I have seen a lot of you out there still struggling with this one.

    Neither of these fixes worked in my particular case however I found another solution. If neither of the above fixes work for you try searching for the update that keeps failing manually. In my case it was KB938123. Every time I tried to update I got the above error message. I searched for ‘download KB938123′ on google and downloaded it to my desktop from the microsoft web site. I then performed a normal manual install. After that the laptop downloaded updates normally.

  7. FallOutBoy says

    He seguido esos pasos y nada, me sale el mismo error

  8. Dan says

    I had already disabled my firewall by stopping the service entirely. It actually turned out that i coulnt install update because of this..
    Enabling the firewall service again, allowed me to continue the install.. Oddness :)
