What is the "Windows Update v8" add-on/control? RRS feed

  • Question

  • I’m using Internet Explorer 11 on 64-bit Windows 7 SP1.

    If I try to access the Microsoft Update Catalog using the following URL:

    http://catalog.update.microsoft.com/

    the blue Microsoft Update Catalog page appears with the globe in the background, the URL changes to:

    http://catalog.update.microsoft.com/v7/site/Install.aspx

    in the Internet Explorer address field, and the following pop-up appears with the message:

    This webpage wants to run the following add-on: ‘Windows Update v8’ from ‘Microsoft Corporation’.

    What is the “Windows Update v8” add-on/control?  I can’t find any reference to it on the Internet.

  • Hi,

    I thinks its a ftp downloads manager from the XP era that was used for TechNet and MSDN downloads on the MS networks. Tools>Manage Addons>Show all addons(or downloaded controls) locate an item in the list you want to inspect and double click it to show its properties sheet. As its an MS internal control, there is unlikely to be any public documentation about it. It should be signed.

    Did you upgrade from XP to Win7?

    Your question indicates that you are not accepting the default IE security zone settings. Tools>Internet Options>Security tab, click "Reset all zones to default". then Trusted sites icon, 'Sites' button, remove any public access domains like *.Microsoft.com

    Regards.

  • Hi Tiberius_Claudius,

    According to your description, do you mean this?

    If it is, it could be a plug-in to control this website. We need install this add-on to search or feedback.

    Hope it will be helpful to you

    Thank you again for the reply, but I'm not sure it helps that much.  As mentioned in the reply to my other query, I haven't upgraded from XP.

    And I do have all IE security zones at their default settings, and the Trusted sites > Sites > Websites box is empty.

    Mm... It's funny you should mention this.

    I needed to be able to use the Microsoft Update Catalog for the first time in order to download the November 2016 security only updates to Windows 7 SP1.  The information I found on the Internet indicated that I should enter the following URL to access the catalog:

    http://catalog.update.microsoft.com/

    And, when I did that for the first time, I got exactly the same pop-up as in your screen shot and I allowed the Microsoft Update Catalog add-on to install.  I then got the second screen shot as shown in your reply.

    Subsequently, I discovered that I should have used the following URL instead:

    http://www.catalog.update.microsoft.com/

    This apparently invokes a new version of the catalog that can be accessed using browsers other than IE.  And it doesn't require the Microsoft Update Catalog add-on.  So, that is when I attempted to remove the Microsoft Update Catalog add-on because it was no longer needed (see my other post yesterday).

    I removed the add-on from Downloaded add-ons, but the add-on still remained in All add-ons.  And now, when I use the URL:

    http://catalog.update.microsoft.com/

    I no longer get the pop-up shown in your reply, I get the one mentioned in my original post, namely:

    This webpage wants to run the following add-on: ‘Windows Update v8’ from ‘Microsoft Corporation’.

    I don't know whether it is significant that the pop-up in your reply uses the word "install", but the pop-up I am now getting uses the word "run".  There is no add-on called "Windows Update v8" listed in All add-ons

    I am wondering whether I should try restoring the system to a restore point earlier than yesterday.  Is that likely to tidy things up?

  • Hi Balubeto,

    Thank you for your reply.

    Based on my test, when we get into the http://www.catalog.update.microsoft.com/ first time, it could prompts a add-on installation. If we install it, the webpage would display the picture in the above post.

    Also we could find the add-on in the Manage add-on function.

    If we disable the Microsoft Update Catalog add-on, the webpage would not display the search or feedback function. We could click the option "more information".

    It could provides the function "You have approved this add-on to run on the following website" and we could know the add-on's file and folder.

    As you said, the system restore is a good choice to get a earlier state.

    Hope it will be helpful to you

    Thanks for clarifying this.  I had been thinking that the ActiveX "basket" tool had been made unnecessary in general but did not realize it only happens with this site.  That could explain a few things.  Otherwise I have been using User-Agent workarounds via either Enterprise Mode or Developer Tools.  Another URL pattern that works is the RSS one someone pointed out to us the last time this site caused users grief.

    https://social.technet.microsoft.com/Forums/en-US/c2b73b22-687d-40b2-a456-a566ae6dffe1/this-months-updates-kb3192440-for-rtm-kb3192441-for-1511-and-kb3194798-for-1607-on-the-way?forum=win10itprogeneral#db10abc8-ab67-4e93-a33c-0a2f4ea48d2a

    Hmm... In fact, this proves that something has changed since then because my example of Edge now works with the old host name.  But who knows there is also a new version of Edge so maybe that's where the fix for this symptom comes from?

    BTW I tried using the Remove button for that add-on (e.g. in Manage Add-ons) but found out that it does not get deleted, just removed from the list, so I am still wondering if there is new version of the add-on that might also help.   (The one I have is 3 years old.)

    Seems absurd to have to do a Restore just to handle this quirk.  Is there no way to safely delete it?  I suppose to be safe you would have to try finding where that add-on is still kept and how (e.g. registry settings).  ProcMon could help.  Otherwise, if you are going to do a Restore how about seeing first what effect really deleting the add-on module has?    ; )

     

    Good luck

    Sorry, Robert, I didn't want to take a chance with such cavalier tactics!  I did a system restore and everything is now back as it should be.  The Microsoft Update Catalog add-on has gone and even its module, MicrosoftUpdateCatalogWebControl.dll, has been deleted from my System32 folder.
