Windows Catalog Website

In a post a while back UsernameIssues referred to the Windows Catalog Website. Update issues. It is in post #6.

What I am trying to get a handle on is when a KB update is updated, how can you find out what KB number is for the updated version? For example KB3102810 appears to have been updated to a newer one. I accidently found it searching around the web. Instead of using the older KB3102810, I would prefer to use the latest update rather than the KB3102810. I could not find the answer to this question by visiting the Windows Catalog Website. https://catalog.update.microsoft.com/v7/site/Home.aspx

Actually I wanted to find out if need be if a KB has a newer one. For instance lets say a fix was introduced 6-1-15 and in 9-1-15 a newer version came out. How can I check to see if a newer version came out? An example is KB3083324 (Sept. 2015) was updated with KB3102810 (Nov. 2015). I know this only because UsernameIssues told me. I want to be able to check and see if one has been updated should I need to.

Use IE to visit the Microsoft®Update Catalog.

Search for the KB of interest.


Select the applicable version for your computer:


Select the tab named Package Details:

Thank soooo much. This will be extremely helpful in my quest to become a computer/network tech. maybe others will see this as well. Great stuff.

I'm assuming that you have to do the updates in sequence. The update may have been changed as a response to newer updates etc. You can always use Disk cleanup to remove obsolete updates.

If an new version of an update has been issued, sometimes MS uses the same KB number and sometimes MS issues a new KB number. Either way, most of the time, you can install the most recent one and it will contain all (most*) of the fixes in the previous versions.

*sometimes the revised version actually drops a particular fix because it was causing problems for some users.

Some KBs have prerequisites that must be installed first. Some KB installers will download and install those KBs for you (i.e. the KB for IE11 on a fresh install of W7),



The KB for the Windows Update Client is a good example. I installed 200+ updates for a fresh W7 install yesterday without manually installing the latest version of the Windows Update Client first. The list of updates to be applied did not contain the 8 old versions of the Windows Update Client. The list only offered me the most recent version: KB3135445
